Its main chip is the Teensy_3.5_3.6_4.1, from the NXP family. Other key parts include the MAX3232. By type, the board carries 5 capacitors, 2 connectors, 1 IC and 1 jumper.

It belongs with the dev boards & breakouts and power & battery designs in this gallery.

From the project

Mount an MCU board on a "Model T" computer

This repo has a few different variations of adapter boards to attach some common small DIP form-factor microcontroller boards directly to "Model T" computers by the serial port.

Particularly, boards with integrated SD card readers, for use with PDDuino, but not limited to that.

You can power the microcontroller board from the computer using a BCR-USB power adapter
