This is the bare PCB you need to build your own 30mm FET + 7135 driver!  DIY parts kit available soon.

This PCB allows for quite a few options---many of which are optional.  It can be run in normal single-cell configuration, zener mod configuration for 2S-4S cells, or with an LDO voltage regulator for 2S-4S cells and momentary use.  

This PCB also has optional provisions for an integrated temperature sensor and PWM output for powering other boards (custom firmware required).

Parts Required (1S Cell):

  • FET: LFPAK56 N-Channel Mosfet
  • 7135
  • D1:  SOD-323 or 0805 Schottky diode
  • C1:  10uF MLC capacitor, 0805 (X6S or X7R preferred)
  • R1:  19.1K, 1% resistor, 0805
  • R2:  4.7K, 1% resistor, 0805
  • UI:  ATTINY13A MCU, SSH or SSU variant
  • 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).

Parts Required (2S-4S Cells - Zener Modified):

  • FET: LFPAK56 N-Channel Mosfet
  • D1:  200 ohm 0805 resistor
  • C2:  10uF MLC capacitor, 0805 (X6S or X7R preferred)
  • R1:  36K, 1% resistor, 0805
  • R2:  4.7K, 1% resistor, 0805
  • Zener Diode:  SOD-123 4.3-5.1v
  • UI:  ATTINY13A MCU, SSH or SSU variant
  • 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). ELECTRONIC SWITCH NOT RECOMMENDED WITH ZENER MOD.  LDO PREFERRED.‚Äč

Parts Required (2S-4S Cells - LDO):

  • FET: LFPAK56 N-Channel Mosfet
  • D1:  EMPTY
  • C1:  10uF MLC capacitor (rated higher than input voltage), 0805 (X6S or X7R preferred)
  • C2: 10uF MLC capacitor, 0805 (X7R preferred)
  • LDO: SOT-23-5 such as AP2204
  • R1:  36K, 1% resistor, 0805
  • R2:  4.7K, 1% resistor, 0805
  • UI:  ATTINY13A MCU, SSH or SSU variant
  • Spring / LED leads
  • OTC:  
    • Pad with side closest to MCU can also be used as electronic switch pad (no OTC installed). Clicky switch usage not recommended with LDO option.
