This 30mm FET+7135 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.

Some of the firmware options use only the FET and not the 7135.  See the listing below.

  1. Driver Only - No Spring or Wires - Generally ships within 3 business days
  2. Driver + Wires Installed - No Spring - Generally ships within 3 business days
  3. Driver + Spring - No Wires - Generally ships within 3 business days
  4. Driver + Wires + Bypassed Spring​ Generally ships within 3 business days

FIRMWARE OPTIONS (FET+7135)


Bistro Clicky Firmware (attiny25)

ToyKeeper hit this one out of the ballpark!  This is similar to the BLF A6 firmware, but with a lot more options: 

  • User configurable mode groups (1-7 modes)
    • Additional mode group for less experienced users, with 3 modes and reduced power
  • User configurable temperature sensor stepdown
  • User configurable memory and mode order (ascending vs. descending)
  • Hidden strobe, battery check, and notification flasher
    • Battery check indicates by a number of flashes between 1 and 8 how full the battery is, with 8 being full and 1 being empty
  • Mode reversing and quick access to turbo from the lowest level
    • A "medium press" reverses modes and gives access to the hidden strobe, battery check, and notification flasher functions

Bistro Configuration Mode

To enter configuration mode, quickly turn off the light 15+ times until it starts to flash.  Once it starts to flash, you are in configuration mode.  

Once in configuration mode, the light will give a solid flash between 1 and 8 times.  The number of solid flashes indicates the option number to be changed.  To select/change the option turn the light off turning the strobing flashes that immediately follow the solid flashes.  

Here are the configuration options:

  1. Simple mode.  3 modes only, with high at about half power.  No moonlight mode, no memory, no medium-press reversing, and high is only about 50% power.
  2. Mode memory.  Enable or disable.
  3. Moonlight mode.  Enable or disable.
  4. Mode order.  L-->H or H-->L (ascending or descending).
  5. Mode group.  The number of flashes indicates the number of modes (excluding moonlight mode).  Groups 1-6 are normal modes, with fairly even spacing between the modes; e.g., Group 1: 100% only; Group 2: 2 evenly spaced modes; Group 6: 6 evenly spaced modes.
  6. Medium-press.  Enable or disable.  This function enables or disables the ability to reverse modes and also to access the hidden modes.
  7. Thermal calibration.  Once you enter this mode, the light will be dim for about 1 second, then go to full brightness.  Once the light reaches the desired maximum temperature, turn the light off and the temperature level will be saved.  To disable the thermal protection, turn the light off during the first ~1 second when the light is dim.
  8. Factory reset.  Resets all options to their original states.

Firmware Options (FET Only)


Standard Clicky Firmware (attiny13a)

  • 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 - 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:

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

Standard Clicky Firmware Low Voltage Protection.  With 2S cells, at around 6V under load (3S: ~9V; 4S ~12V) the light will blink three times then step down the power level.  At around 5V under load (3S: ~7.5V; 4S: ~10V) 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

This firmware allows the ultimate in user customizability, with up to 24 built-in mode groups, that the user can select via a series of button presses and a user programmable turbo timer that will automatically step the power down to 50% after the set time is hit (see below for instructions).  

 

Low voltage protection:  With 2S cells the light will begin to step down output at around 6V under load; 3S ~9V; 4S ~12V.  The light will not shut completely off, but will continue to run at a moonlight level.

Guppydrv ​Instructions

To switch mode groups: rapidly tap the switch 8 times, the light will then enter the programming mode and begin to flash.  With the light in programming mode, tap the switch the same number of times as your desired mode group.  The light will blink and your mode group will be memorized. 

 

Example: To select mode group 3, tap the switch 8 times quickly to enter programming mode.  As soon as the light enters programming mode and beings flashing, tap the switch three times.  The light will blink to recognize the mode group change.

 

To set the turbo timer: rapidly tap the switch 8 times, the light will then enter the programming mode and begin to flash.  With the light in programming mode, tap the switch 30 times to enter the turbo timer set mode.  The light will then switch to 100% power.  When the light is at the desired temperature for the turbo step down, turn the light off.  The turbo timer will then be set.  The turbo timer steps the light down to 50% regardless of the mode group set.  

 

To lock the mode groups: Solder Pin 5 to ground.  

 


Turbo Timer

A turbo timer may help reduce the chance of overheating.

Bistro / guppydrv / 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.

 Available Options:

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

FREQUENTLY ASKED QUESTIONS:

1. What Is The Input Voltage Range?

  • 6V-18V (2S-4S)
  • This is a "direct drive" driver, meaning it doesn't step up or down voltage that the LED sees.  
    • Examples of workable LED + battery combinations:
      • 2S Input (two cells in series):
        • 6V XHP50/XHP70
        • 6V MT-G2
        • Two 3V LEDs in Series
      • 3S Input (three cells in series):
        • Three 3V LEDs in series
      • 4S Input (four cells in series):
        • 12V XHP50/XHP70
        • Four 3V LEDs in series

2. What Kind Of Output Can I Expect?

  • Output is generally limited by cell selection, LED type, and other connections (such as springs and emitter wires).  

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).  If you'd like to learn more about these drivers, and participate in further development, come visit our community at budgetlightforum.com
