E-Paper Badge with Teensy LC designed in KiCad
E-Paper badge designed in KiCad to connect Pervasive Displays 2.15" E-Paper (E2215CS062) to Teensy LC. (Teensy 3.2 is also compatible). Based Teensy E-Paper Shield by Jarek Lupinski in EAGLE.
KiCad PCB design files:
- repo: kicad-teensy-epaper
- commit: Reworked layout for aesthetics [0a40263]
- requires KiCad library wickerlib by Jenner Hanni of Wickerbox Electronics for the 34-position FPC connector that the e-paper display plugs into:

Battery Power
- These products are used to power the badge from a battery.
- LiPo battery charger add-on for Teensy 3.1 from Pesky Products on Tindie
- WARNING: The trace between VIN and VUSB must be cut! Here is an demostration of cutting the trace on Adafruit Learning System.
- Lithium Ion Polymer Battery - 3.7v 500mAh from Adafruit
- Initial capacity chosen for a good trade off between weight and power. I have not yet measured how long it will run with different capacities.
Source Code
- uses EPD215 Arduino Library by Jarek Lupinski for his E-paper Teensy Shield
- requires pinout modification:
- EpaperQuoteDisplay.ino
EPD215 epaper( 17, 16, 14, 15, 13, 11 );
