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.

SparkFun Thing Plus – ESP32 WROOM

The SparkFun ESP32 Thing Plus is the next step to get started with Espressif IoT ideations while still enjoying all the amenities of the original ESP32 Thing. Espressif’s ESP32 WROOM is a powerful WiFi and Bluetooth MCU module that targets a wide variety of applications. At the core of this module is the ESP32-D0WDQ6 chip which is designed to be both scalable and adaptive. To make the Thing Plus even easier to use, we’ve moved a few pins around to make the board Feather compatible and it utilizes our handy Qwiic Connect System which means no soldering or shields are required to connect it to the rest of your system. A JST connector to plug in a LiPo battery.

SparkFun Qwiic MP3 Trigger

Sometimes you just need an MP3 to play. The SparkFun Qwiic MP3 Trigger takes care of all the necessary requirements, all you need to do is send a simple I2C command and listen to whatever is on your micro SD card. The contents of the microSD card appears as a jump drive. Simply plug in the Qwiic MP3 Trigger and you’ll be transferring MP3s, no need for drivers and no need for WAV or Vorbis conversion. Your supplied speaker is boosted by a Class-D mono amplifier capable of outputting up to 1.4W making it capable of being incredibly loud. Volume is software selectable between 32 levels.
