This version is for a momentary / electronic switch with 2S+ cells on the input. If your light disconnects the power to the driver to turn on/off, then this is not the driver you need.
This 26mm FET driver features an ultra low resistance FET that gives you near-direct-drive performance (limited mostly by your battery, LED, and connections) with the ability to still use lower power levels, among other functions such as low voltage protection.
All of the firmware options for this driver use only the FET and not the 7135. Please reference the firmware options, below.
For the 1S (single lithium-ion cell) version, click here.
For the 2S clicky version, click here.
Because each driver is hand-built and tested, This driver may take up to 10 business days to build, test, and ship.
Wires + Spring Option
There are four different options for how you would like your driver to be configured:
Firmware Options (FET Only)
Standard Momentary Firmware (attiny13a)
moppydrv Multi-Group Electronic Switch Firmware (attiny13a)

D4 V2 UI Electronic Switch Firmware (attiny85)
A turbo timer may help reduce the chance of overheating.
moppydrv / D4 V2 firmwares do NOT use a fixed turbo timer. Instead, you program in your own turbo timer or set your temperature sensor level.

This driver was made possible and is heavily inspired by many members of the BLF flashlight community, especially comfychair (initial concept and development), Mattaus (PCB layout and development), JonnyC (firmware), DrJones (firmware), and wight (singe-sided PCB development and advice).
