Quad 7-Segment Display Teensy Hat
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.
The KiCad schematic and layout are available at the Github repo. The project is released as open hardware under the CERN v1.2 Open Hardware license.
The project uses the Teensy template and footprint from wickerlib.
You can buy a set of bare boards at OSH Park for $5.20 here.

The best way to place the LCD 7-Segment Display and the Teensy 3.2 is to buy one 40-position header (it’s the cheapest option, about $0.50) and snap it apart into the sections you need.
The Teensy 3.2 can be bought from OSH Park at checkout, or from PJRC.
