SparkFun – Polymer Lithium Ion Battery – 110mAh

SparkFun PRT-00731 Mk01

SparkFun PRT-00731 Mk02

SparkFun PRT-00731 Mk03

SparkFun: PRT-00731

Description: This is a very small, extremely light weight battery based on the new Polymer Lithium Ion chemistry. This is the highest energy density currently in production. Each cells outputs a nominal 3.7V at 110mAh! Comes terminated with a standard 2-pin JST-PH connector – 2mm spacing between pins. These batteries require special charging. Do not attempt to charge these with anything but a specialized Lithium Polymer charger.

Battery includes built-in protection against over voltage, over current, and minimum voltage. Please use caution when using this battery in wearable projects. When using conductive thread, a short in the thread can create sparks and heat. We recommend using coin cell batteries for beginners.

Note: Be careful with the JST connectors. They can stick in pretty good and tugging on them can damage the connector.

Dimensions: 5.7x12x28mm

Weight: 2.65g

Features:

  • Excellent long-term self-discharge rates (<8% per month)
  • Robust power source under extreme conditions (-25 to 60C)

Description

Oh say can you see
By the knob’s early light…

Sorry – we thought that was clever. And while it wasn’t really, this potentiometer knob definitely is. It’s a ‘soft touch’ T18 knob that works great with our Panel Mount 10K, Panel Mount 1K, and Panel Mount 100K potentiometers. The knob is designed to set directly on the potentiometer’s ridges so it’s an easy & secure fit. It has a nice feel, with a rubbery grip, tweaking it is quite fulfilling.

This is the blue version and it has a nice deep color on the inside with a striking blue line on the outside for great visibility with whatever you’re making. We also carry it in white and red if you’re looking for a variety of colors.

Technical Details

  • Diameter of the top: 11mm / 0.4″
  • Diameter of the base: 15mm / 0.6″
  • Weight: 1g
  • Colour: Blue

Adafruit – Standard LCD 20×4 + Extras – White on Blue

Adafruit 198 Mk01

Adafruit 198 Mk02

Adafruit 198 Mk03

Adafruit: 198

Description

Standard HD44780 LCDs are useful for creating standalone projects.

  • 20 characters wide, 4 rows
  • White text on blue background
  • Connection port is 0.1″ pitch, single row for easy breadboarding and wiring
  • Single LED backlight with a resistor included, you can power it directly from 5V. If it’s too bright for you, it can be dimmed easily with a resistor or PWM and uses much less power than LCD with EL (electroluminescent) backlights
  • Can be fully controlled with only 6 digital lines!
  • Built in character set supports English/Japanese text, see the HD44780 datasheet for the full character set
  • Up to 8 extra characters can be created for custom glyphs or ‘foreign’ language support (like special accents)
  • Comes with necessary contrast potentiometer and strip of header

For more information, check out our detailed step-by-step Arduino+LCD tutorial

We have a generic 20×4 datasheet that has dimensions and pin-locations (the exact model may vary but the pinout, size and protocol information is the same). We also have a HD44780 datasheet with the detailed commands for control.
