Summary

  • Switches: MX-style switch cutouts in a 6×? matrix layout; stabilizer cutouts at long-key positions (Space, Enter, Shift).
  • Diodes: Individual SMD diodes located adjacent to each switch column for matrix isolation.
  • MCU: Main microcontroller (QFP or QFN package) near the top-center with crystal/resonator and decoupling capacitors.
  • USB connector: Type-C port at top edge with ESD diodes and VBUS filtering components.
  • Indicators: RGB or dual-color status LEDs near the MCU and/or in top-right corner.
  • Reset/Program: Small tactile button labeled RESET/BOOT close to the MCU for flashing firmware.
  • Switch LEDs: Optional per-key LED pads (single or RGB) arranged around switch cutouts.
  • Test points: Labeled TP pads for VCC, GND, SDA, SCL, TX, RX along a top-row for programming/debug.
