This is the bare PCB you need to build your own 20mm FET driver!  DIY parts kit available here.

This updated version makes spring bypasses a breeze---simply run your LED+ wire directly to the spring.

Parts Required:

  • FET: LFPAK56 N-Channel Mosfet
  • D1:  SOD-323 Schottky diode
  • C1:  10uF MLC capacitor, 0805 (X7R preferred)
    • Populate CZNR instead of C1 if used zener modified
  • R1:  19.1K, 1% resistor, 0805
    • Use 36K 1% 0805 resistor for 2S or 3S zener mod LVP
  • R2:  4.7K, 1% resistor, 0805
  • UI:  ATTINY13A MCU, SSH or SSU variant
  • Z: SOD-323 4.3v or 5.1v zener diode
    • If zener diode is used:
      • populate CZNR instead of C1 with 10uF capacitor
      • replace D1 with 200 ohm resistor
  • Spring / LED leads
  • OTC:  1uF MLC capacitor, 0805 (X7R preferred)
    • Pad with side closest to MCU can also be used as electronic switch pad (no OTC installed).

The parts layout is the same for the 17mm and 20mm boards.
