Features:

  • 64 inputs
  • one common wire for all 64 inputs
  • one wire for each switch's second terminal
  • no ghosting
  • more wires, but wiring is easier to understand and track
    • no figuring out which X-matrix-wire goes with which Y-matrix-wire (as you have to do with the other Keymatrix Daughterboards)
  • connectors: pinheaders for IDC ribbon flat cables
  • board size: 80x100mm (half euro size)
