Writeup

• 4x5 macropad with 2 LED screens, pretty basic tbh

Overview of macropads

• can use as small keyboard if you connect all 3
• can use for macros like copy, paste etc.

PCB

• wires up in column and row config, with diodes in Column to row config
• backlit using some small LEDs
• Hotswap compatible
• If the PCB can be White or Black that would be cool (or any fun color that's not green or blue <3)
• I will solder all the surface mount components :)

CAD

• case has 10/11 parts
• the standoffs will be 3d printed, can print myself
• all DXF files can be made out of acrylic

Firmware

• uses I2C to output to displays - currently just text, but have a way to do images but its only coded in my head atm
• uses kmk to make the keyboard board
