This is the bare PCB you need to build your own 17mm FET+7135 driver! DIY parts kit available here.
- FET: LFPAK56 N-Channel Mosfet
- 7135: AMC7135 Linear Regulator
- D1: SOD-323 / 0805 Schottky diode
- C1: 10uF MLC capacitor, 0603 (X7R preferred)
- R1: 19.1K, 1% resistor, 0805
- R2: 4.7K, 1% resistor, 0805
- UI: ATTINY13A MCU, SSH or SSU variant
- * symbol indicates MCU Pin 1 location
- 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).
