This is the bare PCB you need to build your own 17mm FET driver! DIY parts kit available here.

This PCB is 1.6mm thick with heavy 2 oz. copper and red solder resist. Same parts as most previous MTN-17DD drivers.

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 4.3-5.1v 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 layout is the same for both 17mm and 20mm FET only boards.
