This is probably the most popular flashlight driver controller in the world! It is what powers the Nanjg 105C/qlite, Nanjg AK47A, FET drivers, and almost all other drivers out there.
These units are made available for those who want to reflow these chips onto your own drivers.
Available as both bare unflashed and pre-programmed. For the STAR FW options there may be a 1-3 business day handling time for the custom programming.
PROGRAMMING FIRMWARE OPTIONS. Different options are available for 7135 and FET based drivers, both clicky and momentary. Please choose the appropriate firmware type for the type of driver you would like to build.
7135 Based Clicky Firmware:
guppydrv Universal Firmware
***REQUIRES 1uF CAPACITOR ON PIN 2/STAR 4***
Optional guppydrv Universal Firmware
This firmware allows the ultimate in user customizability, with 22 built-in mode groups, that the user can select via a series of button presses and a user programmable turbo timer (see below for instructions).
User Selectable Groups:
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 starts flashing, tap the switch three times (for group 3). 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. Turbo timer drops down to 50% output.
To lock the mode groups: Solder Star 2 to ground. The other stars have no function with this firmware.
STAR Off-Time Firmware
***REQUIRES 1uF CAPACITOR ON PIN 2/STAR 4***
This firmware will allow you to fully customize your light! Moonlight and mode order are all selectable via solderable stars (see below).
When selecting this option, please define the following in your checkout comments:
star | open | closed (soldered) |
1 | DUMMY STAR | NOT CONNECTED IN ANY WAY |
2 | No Moonlight Level | Moonlight |
3 | ascending mode order (moon)-L/M/H | descending mode order H/M/L/(moon) |
4 | CAPACITOR | CAPACITOR |
Off-time changes the way that the memory function works, making it much more intuitive to use. If "memory" is chosen, one tap will always change modes and switching the light off will always save the last mode used. If "no memory" is chosen, the light will always switch modes with a single tap, but will return to the first mode after the light has been switched off.
Because Star 4 is occupied by the capacitor with this firmware, you must choose whether or not you want memory when placing your order.
NLITE firmware:
NLITE Turbo Timer: Same features as normal NLITE firmware but with an automatic step down to medium power after either 90 or 120 seconds. The user can immediately kick the light back up to high mode if needed. This is GREAT for the MT-G2 mods and any smaller light pushing a lot of power! Helps prevent accidental overheating.
3 Modes: Low (5%) - Medium (33%) - High (100%)
4 Modes: Moonlight - Low (5%) - Medium (33%) - High (100%)
star | open | closed (soldered) |
1 | DUMMY STAR | NOT CONNECTED IN ANY WAY |
2 | 3 modes L/M/H | 4 modes, additional moon level |
3 | ascending mode order (moon)/L/M/H | descending mode order H/M/L/(moon) |
4 | mode memory | no memory |
The NLITE firmware is written by BLF forum member DrJones, and is available freely for both personal and commercial use. You can see the rest of his awesome drivers at his website.
FET Based Firmware:
Standard FET Clicky Firmware Options
***REQUIRES 1uF CAPACITOR ON PIN 2/STAR 4***
Clicky Pin Functions. Soldering these numbered pins to ground will enable these features:
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.
FET guppydrv Clicky Firmware Option
***REQUIRES 1uF CAPACITOR ON PIN 2/STAR 4***

FET Electronic Switch Firmware Options
Standard 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.
FET + 7135 Clicky Firmware Options
***REQUIRES 1uF CAPACITOR ON PIN 2/STAR 4***
***DESIGNED FOR A 350mA 7135 ON PIN 5 AND AN FET ON PIN 6***
