Micro Journal - DIY Kit - 68 keys Keyboard PCB

A 68-key hot-swap keyboard PCB for Micro Journal

This is the keyboard board used in Micro Journal Rev.2.1, Rev.4, Rev.7 and Rev.8. Order a single board for a new build, a repair or an upgrade.

Why you will like it

• No soldering for the switches. The hot-swap sockets accept Cherry MX compatible switches (3-pin and 5-pin), so you can install or change switches at any time.
• Made for Micro Journal. The 68-key layout and the pinout are designed for the Micro Journal firmware and mainboards, so it connects directly.
• Order just one. Custom PCBs normally have to be ordered in bulk. I keep ready-to-ship stock with Elecrow, so one board is all you need.
• Open source. Every file is public, from the manufacturing files to the schematic.

Good to know

• Keyboard switches and keycaps are not included. Use any Cherry MX compatible switches you like.
• Compatible with Micro Journal Rev.2.1, Rev.4, Rev.7 and Rev.8.
• It also fits the keyboard in the Micro Journal DIY kits, so you can use it to replace a board.
• The board has connection holes for the microcontroller and for an EC11 rotary encoder.
