Pololu Adjustable Step-Up Voltage Regulator U1V11A

This compact U1V11A switching step-up voltage regulator efficiently boosts input voltages as low as 0.5 V to an adjustable output voltage between 2 V and 5.25 V. Unlike most boost regulators, the U1V11A offers a true shutdown option that turns off power to the load, and it automatically switches to a linear down-regulation mode when the input voltage exceeds the output. The pins have a 0.1 inch spacing, making this board compatible with standard solderless breadboards.

NeoPixel Stick – 8 x 5050 RGB LED

Make your own little LED strip arrangement with this stick of NeoPixel LEDs. We crammed 8 of the tiny 5050 (5mm x 5mm) smart RGB LEDs onto a PCB with mounting holes and a chainable design. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC.

IMU

Accelerometers, gyroscopes and magnetometer are great, but alone they don’t give you quite enough information to be able to comfortably calculate things like orientation, position, and velocity. To measure those and other variables many people combine the two sensors, to create an inertial measurement unit (IMU) which provides two to nine degrees of freedom (DOF). IMUs are widely used in devices that require knowledge of their exact position, for example robotic arms, guided missiles, and tools used in the study of body motion.

IMUs can really be broken down into two classes: simple IMU combo boards, which just mount an accelerometer, gyroscopes and magnetometer onto a single PCB, and more complex units that interface a microcontroller with the sensors to produce a serial output. If you’ve glanced over the previous sections, you should know what kind of specifications to be looking for in IMUs: the number of axes (both for the accelerometer, gyroscopes and magnetometer), the measuring range of the sensors, and the interface.

Pololu MinIMU-9 v5 Gyro, Accelerometer, and Compass

The Pololu MinIMU-9 v5 is an inertial measurement unit (9DoF IMU) that packs an LSM6DS33 3-axis gyro and 3-axis accelerometer and an LIS3MDL 3-axis magnetometer onto a tiny board. An I²C interface accesses nine independent rotation, acceleration, and magnetic measurements that can be used to calculate the sensor’s absolute orientation. The MinIMU-9 v5 board includes a voltage regulator and a level-shifting circuit that allow operation from 2.5 to 5.5 V, and the pin spacing makes it easy to use with standard solderless breadboards and perfboards.

STMicroelectronics LSM6DS33

The LSM6DS33 is a system-in-package featuring a 3D digital accelerometer and a 3D digital gyroscope performing at 1.25 mA in high-performance mode and enabling always-on low-power features for an optimal motion experience for the consumer. ST’s family of MEMS sensor modules leverages the robust and mature manufacturing processes already used for the production of micromachined accelerometers and gyroscopes.

STMicroelectronics LIS3MDL

The LIS3MDL is an ultra-low-power high-performance three-axis magnetic sensor. The LIS3MDL has user-selectable full scales of gauss. The self-test capability allows the user to check the functioning of the sensor in the final application. The device may be configured to generate interrupt signals for magnetic field detection.

Terminal Block Breakout FeatherWing

The Terminal Block Breakout FeatherWing kit is like the of prototyping FeatherWings. To start, you get a nice prototyping area underneath your Feather, with extra pads for ground, 3.3V and SDA/SCL. There’s also four mounting holes so you can attach the breakout to your enclosure or project.

This product works with all our Feathers. The terminal blocks allow you to connect to any of the external Feather pins, great for wiring temporary or permanent installations. We also give you a few extra terminal block pins for ground and 3.3V connections since those are so useful.

FeatherWing Proto

This is the FeatherWing Proto – a prototyping add-on for all Feather boards. This has a duplicate breakout for each pin on a Feather, as well as a bunch of plain grid proto holes. For GND and 3.3V, we give you a strip of connected pads. There’s plenty of room for buttons, indicator LEDs, or anything for your portable project. The FeatherWing Proto makes an ideal partner for any of our Feather boards.

SparkFun Environmental Combo Breakout – CCS811/BME280 (Qwiic)

The SparkFun CCS811/BME280 Environmental Combo Breakout takes care of all your atmospheric-quality sensing needs with the popular CCS811 and BME280 ICs. This unique breakout provides a variety of environmental data, including barometric pressure, humidity, temperature, TVOCs and equivalent eCO2 levels. To make it even easier to use this breakout, all communication is enacted exclusively via I2C, utilizing our handy Qwiic system. However, we still have broken out 0.1″ spaced pins in case you prefer to use a breadboard.

Bosch Sensortec BME280

The BME280 is as combined digital humidity, pressure and temperature sensor based on proven sensing principles. Its small dimensions and its low power consumption allow the implementation in battery driven devices such as handsets, GPS modules or watches. The BME280 achieves high performance in all applications requiring humidity and pressure measurement. These emerging applications of home automation control, indoor navigation, health care as well as GPS refinement require a high accuracy and a low TCO at the same time. The humidity sensor provides an extremely fast response time for fast context awareness applications and high overall accuracy over a wide temperature range. The pressure sensor is an absolute barometric pressure sensor with extremely high accuracy and resolution.

Typical Application

-Context awareness, e.g. skin detection, room change detection
-Health monitoring / well-being
-Warning regarding dehydration or heat stroke
-Spirometry (measurement of lung volume and air flow)
-Home automation control
-Control heating, venting, air conditioning (HVAC)
-Internet of Things
-GPS enhancement (e.g. time-to-first-fix improvement, dead reckoning, slope detection)
-Indoor navigation (change of floor detection, elevator detection)
-Outdoor navigation, leisure and sports applications
-Weather forecast
-Vertical velocity indication (rise/sink speed)

Target devices

-Handsets such as mobile phones, tablet PCs, GPS devices
-Navigation systems
-Gaming, e.g flying toys
-Camera (DSC, video)
-Portable health care devices
-Home weather stations
-Flying toys
-Watches

ams AG CCS811

The CCS811 is an exceedingly popular sensor, providing readings for equivalent eCO2 in the PPM and total volatile organic compounds in the PPB. The CCS811 is an ultra-low power digital gas sensor solution which integrates a metal oxide (MOX) gas sensor to detect a wide range of Volatile Organic Compounds (VOCs) for indoor air quality monitoring with a microcontroller unit (MCU), which includes an Analog-to-Digital converter (ADC), and an I²C interface.

Adalogger FeatherWing – RTC + SD

A Feather board without ambition is a Feather board without FeatherWings. This is the Adalogger FeatherWing: it adds both a battery-backed Real Time Clock and MicroSD card storage to any Feather main board. This FeatherWing will make it real easy to add datalogging to any of our existing Feathers. You get both an I2C Real Time Clock (PCF8523) with 32KHz crystal and battery backup, and a MicroSD socket that connects to the SPI port pins.

MicroSD Card

If you have a project with any audio, video, graphics, data logging, etc in it, you’ll find that having a removable storage option is essential. Most microcontrollers have extremely limited built-in storage. If you’re doing any sort of data logging, graphics or audio, you’ll need at least a megabyte of storage, and 64M is probably the minimum.

MicroSD cards are ‘raw’ storage. They’re just sectors in a flash chip, there’s no structure that you have to use. That means you could format an SD card to be a Linux filesystem, a FAT (DOS) filesystem or a Mac filesystem. You could also not have any filesystem at all. However, 99% of computers, cameras, MP3 players, GPS loggers, etc require FAT16 or FAT32 for the filesystem. The tradeoff here is that for smaller microcontrollers the addition of the complex file format handling can take a lot of flash storage and RAM.

Global Positioning System (GPS)

The Global Positioning System (GPS) is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. Obstacles such as mountains and buildings block the relatively weak GPS signals.

A satellite navigation device, colloquially called a GPS receiver, or simply a GPS, is a device that is capable of receiving information from GNSS satellites and then calculate the device’s geographical position. Using suitable software, the device may display the position on a map, and it may offer routing directions. The Global Positioning System (GPS) is one of a handful of global navigation satellite systems (GNSS) made up of a network of a minimum of 24, but currently 30, satellites placed into orbit by the U.S. Department of Defense.

A satellite navigation device can retrieve (from one or more satellite systems) location and time information in all weather conditions, anywhere on or near the Earth. GPS reception requires an unobstructed line of sight to four or more GPS satellites, and is subject to poor satellite signal conditions. Today, most standalone GPS receivers are used in automobiles. The GPS capability of smartphones may use assisted GPS (A-GPS) technology, which can use the base station or cell towers to provide a faster Time to First Fix (TTFF), especially when GPS signals are poor or unavailable. However, the mobile network part of the A-GPS technology would not be available when the smartphone is outside the range of the mobile reception network, while the GPS aspect would otherwise continue to be available.

GPS Receiver – GP-20U7

The GP-20U7 is a compact GPS receiver with a built-in high performances all-in-one GPS chipset. The GP-20U7 accurately provides position, velocity, and time readings as well possessing high sensitivity and tracking capabilities. Thanks to the low power consumption this receiver requires, the GP-20U7 is ideal for portable applications such as tablet PCs, smart phones, and other devices requiring positioning capability.

This 56-channel GPS module, that supports a standard NMEA-0183 and uBlox 7 protocol, has low power consumption of 40mA@3.3V (max), an antenna on board, and -162dBm tracking sensitivity. With 56 channels in search mode and 22 channels “all-in-view” tracking, the GP-20U7 is quite the work horse for its size.

This one is unused and doesnt have a conection TX pin.

NMEA V3.01 Protocol

  • Its output signal level is TTL: 9600bps (default), 8 bit data, 1 stop bit and no parity
  • It supports the following NMEA-0183
  • Messages: GGA, GLL, GSA, GSV, RMC and VTG

NMEA-0183 Output Messages

  • NMEA: Record Description
  • GGA: Global positoning system fixed data
  • GLL: Geogrphic position – latitude / longitude
  • GSA: GNSS DOP and active satellites
  • GSV: GNSS satellites in view
  • RMC: Recommended minimum specific GNSS data
  • VTG: Course over ground and ground speed

Adafruit SHARP Memory Display Breakout – 1.3 Inches – 168 Pixels x 144 Pixels Monochrome

The 1.3 inches 168 pixels x 144 pixels SHARP Memory LCD display is a cross between an eInk display and an LCD. It has the ultra-low power usage of eInk and the fast-refresh rates of an LCD. This model has a gray background, and pixels show up as black-on-gray for a nice e-reader type display. It does not have a backlight, but it is daylight readable. For dark/night reading you may need to illuminate the LCD area with external LEDs.

The display is write only which means that it only needs 3 pins to send data. However, the downside of a write-only display is that the entire 168×144 bits must be buffered by the microcontroller driver. That means you cannot use this with an ATmega328 or ATmega32u4. You must use a high-RAM chip such as ATSAMD21, Teensy 3, ESP8266, ESP32, etc. On those chips, this display works great and looks wonderful.

DS3231 Precision RTC FeatherWing

A Feather board without ambition is a Feather board without FeatherWings. This is the DS3231 Precision RTC FeatherWing: it adds an extremely accurate I2C-integrated Real Time Clock (RTC) with a Temperature Compensated Crystal Oscillator (TCXO) to any Feather main board. This RTC is the most precise you can get in a small, low power package. Most RTCs use an external 32kHz timing crystal that is used to keep time with low current draw. And that’s all well and good, but those crystals have slight drift, particularly when the temperature changes. This RTC is in a beefy package because the crystal is inside the chip. And right next to the integrated crystal is a temperature sensor. That sensor compensates for the frequency changes by adding or removing clock ticks so that the timekeeping stays on schedule.

SparkFun Micro OLED Breakout (Qwiic)

The SparkFun Qwiic Micro OLED Breakout is a Qwiic-enabled version of our popular Micro OLED display. The small monochrome, blue-on-black OLED screen presents incredibly clear images for your viewing pleasure. The OLED display is crisp, and you can fit a deceivingly large amount of graphics on there. This breakout is perfect for adding graphics to your next project and displaying diagnostic information without resorting to a serial output, all with the ease of use of our own Qwiic Connect System.
