Hi,
My son is an online air traffic controller for VATSIM and wanted to create a replica STARS ATC keyboard. This is essentially a USB keyboard with 90 keys. Keys will be Cherry MX browns. I'm planning on using matrix addressing with a Teensy 3.2.
I wanted to see if anyone had any comments or corrections on the schematic before I moved on to PCB layout.
This will be implemented via USB cable into the Teensy and then digital I/O to address the matrix. All column pins will be set to outputs and all rows will be set to inputs.
Thanks in advance for any advice.
Here is the current schematic.
This is what we are trying to replicate.
