This kit contains all of the parts, except for the PCB itself, that you need to assemble your own single-sided MTN-15DD 15mm FET driver.  You can get the 15mm MTN-15DD PCB here. 

Each Kit Includes:

  • Low-Resistance N-Channel LFPAK33 MOSFET
  • Pre-Programmed Attiny13a MCU 
  • 10uF X6S MLCC Ceramic Capacitor
  • 1uF X7R Ceramic Capacitor "Off-Time"
  • 4.7k Resistor
  • 19.1k Resistor
  • SOD-323 Diode
  • Gold-Plated Spring
  • Small Length of Solder Wick 
  • Pair of 22 AWG Silicone Wires

Standard Clicky Firmware Options

  • Standard FET with Memory.  This is the most popular option.  Equipped with off-time memory, mode changes are intuitive and the light always picks right back up where you left off. 
    • Mode Levels:  Moonlight (Solder #2 to ground) - 2% - 5% - 20% - 50% - 100%
  • Standard FET with No Memory.  This is the second most popular option.  Equipped with off-time no memory, the light will always start on the first mode level after being turned off.  
  • Custom Mode Levels.  Choose your own mode levels.  For this option, please enter the following information in your checkout comments:  
    • 1.  Number of light levels: 1-6 (plus moonlight if desired)
    • 2.  Approximate PWM levels of each mode:  Example: (1) 2% - (2) 15% - (3) 40% - (4) - 100%
    • 3.  Memory or No Memory

Clicky Pin Functions.  Soldering these numbered pins to ground will enable these features:

  • enables moonlight mode.
  • reverses mode order from the standard ascending (low to high) to descending (high to low).

Standard Clicky Firmware Low Voltage Protection.  At around 3V under load, the light will blink three times then step down the power level.  At around 2.6V under load the light will blink ten times then shut off.  This system gives you ample warning and attempts to extend runtime before turning the light off. 


Universal guppydrv Clicky Firmware Option (Revs. 1 & 2)

Electronic Switch Firmware Options

  • Standard FET Electronic Switch.  This is for use with an external electronic switch, where the driver is always powered, not for use with a standard clicky switch where power is cut by the switch to change modes.  This option uses STAR momentary firmware, which allows you to start on either the lowest or highest mode from off with either a short tap or long press of the switch.  
    • One side of the switch is soldered to ground, the other to the pre-tinned switch pad on the driver (connected to pin 2).
  • Custom Mode Levels.  Choose your own mode levels.  For this option, please enter the following information in your checkout comments:  
    • 1.  Number of light levels: 1-6 (plus moonlight if desired)
    • 2.  Approximate PWM levels of each mode:  Example: (1) 2% - (2) 15% - (3) 40% - (4) - 100%
  • Not recommended for use with the Zener Mod option (see below).

‚ÄčStandard Electronic Switch Firmware Low Voltage Protection.  At around 3V under load, the light will step down the power level.  At around 2.6V under load the light will shut off.  You can override any low voltage shut down by holding down the electronic switch button.  This system gives you ample warning and attempts to extend runtime before turning the light off.  


Turbo Timer (N/A for guppydrv FW)

A turbo timer may help reduce the chance of overheating.  Available Options:

  • No Timer
  • 30 Seconds
  • 60 Seconds
  • 90 Seconds
  • 120 Seconds
  • 180 Seconds

These PCBs and firmware are the result of the efforts of many of the members of the BLF community.  For more information, check out this thread.
