## Design
|
||
|
|
|
||
|
|
This is a column-driven split keyboard using three custom PCBs connected with ribbon cables. The left and right PCBs are
|
||
|
|
passive: they only have the diodes and switches needed to make the matrix. The center PCB has an Adafruit Feather 32u4 and
|
||
|
|
MCP23017 expander.
|
||
|
|
|
||
|
|
The left matrix has its rows and columns directly connected to the Feather. The right matrix has its rows connect to the
|
||
|
|
Feather (using the same pins as the left matrix) and its columns connected to the expander. The expander uses the LUFA
|
||
|
|
hardware TWI driver.
|
||
|
|
|
||
|
|
Bluetooth is enabled.
