Its main chip is the teensy2, from the NXP family. By type, the board carries 61 diodes, 4 resistors, 2 modules, 2 crystals, 2 connectors and 1 IC.

From the project

a replacement pcb for the Apple M0110

A prototype replacement pcb for the Apple M0110 keyboard.

This pcb uses the Adafruit Feather 32u4 Bluefruit LE or a Teensy 2.0 controller to send keycodes to the connected computer.

1. Teensy 2.0 x 1 2. Your favorite MX style switches x 60 3. 1N4148 switch diodes x 60

If you're going the bluetooth route you will need the following additional items: 1. GPIO Expander (MCP23017-E/SP-ND) x 1 2. Lithium Ion battery x 1. I chose the biggest I could find on Amazon that fit inside the original Apple M0110 case. 3. Adafruit Bluefruit 32u4 module instead of the Teensy 4. 4.7k Ohm Resistors x4
