E-Paper badge designed in KiCad to connect Pervasive Displays 2.15" E-Paper to Teensy LC. (Teensy 3.2 is also compatible). Based Teensy E-Paper Shield by Jarek Lupinski in EAGLE.
- repo: kicad-teensy-epaper
- commit: add JST connector for lipo battery [abcafec]
- requires KiCad library wickerlib by Jenner Hanni of Wickerbox Electronics for the 34-position FPC connector that the e-paper display plugs into:
- OSH Stencils: stainless steel stencil
- Teensy LC sold by OSH Park. Designed and manufactured by PJRC.
- Teensy 3.2 is also compatible but more expensive

- WARNING: The trace between VIN and VUSB must be cut!
- Demostration of cutting the trace on Adafruit Learning System.
- Lithium Ion Polymer Battery - 3.7v 500mAh from Adafruit
- capacity chosen for a good trade off between weight and power
- TODO: measure how long board will run with different capacities.
- uses EPD215 Arduino Library by Jarek Lupinski for his E-paper Teensy Shield
- requires pinout modification:
- example: bringahackmfba17-dorkbotpdx.ino
EPD215 epaper( 17, 16, 14, 15, 13, 11 );
- rotation hack in
EPD215.cpp- text and graphics wil be upside down without this
- quick hack to set rotation based on Adafruit documentation:
- Landscape mode:
_rotation = 1
- Portrait mode:
_rotation = 2
- I don't use this for the examples program that just display bitmaps as I just flip the image before generating the byte array from the bitmap file
TODO: library should be modified to accept rotation parameter
