7-Segment Display Teensy Hat

7-Segment display daughter board for the Teensy 3.2 with onboard microSD card.

I'll share the boards at OSH Park when the design is verified. You can buy a set of three for $5.20.

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.
