7-Segment display daughter board for the Teensy 3.2 with an additional SD card connector for reading from. The included code adapts the SevSeg library for the pins used here.
I’ve shared the project at OSH Park so you can buy a set of three bare boards for $5.20, or $1.74 per board.
The rest of the parts are available at Digikey. If this is your first time building a board, check out our assembly howto and remember to always buy a few extra of the resistors. They’re very small, easy to lose, and often cost 30 cents for three but a dollar for 100.
