KBDevBoard

KBDevBoard is a development board for rapid prototyping of keyboard circuitry.

I use this to test new MCUs with QMK before designing custom PCBs.

How to use this with DIRECT_PINS?

• Connect DIRECT_PINS to the pin headers in the middle.
• Connect the five pin headers at the top to GND.
• Don't use any of the pin headers at the bottom.
• Soldering the diodes is not required, but it isn't harmful either.

How to use this with COL2ROW?

• Connect MATRIX_ROW_PINS to the pin headers at the top.
• Connect MATRIX_COL_PINS to the pin headers at the bottom.
• Don't use any of the pin headers in the middle.
• Make sure that you soldered the diodes.

Why are there ten pin headers for only five rows at the top?

There are two pin headers for each row. This is convenient when you want to connect all rows to GND. Use a jumper each to shortcut pin headers 1 + 2, 2 + 3, 3 + 4 and 4 + 5. Connect GND to one of the two remaning pin headers 1 or 5.
