This is a great driver when you need a single sided low profile 17mm driver for your project.  It can be used with the default firmware or flashed with one of the alternate firmwares (see below).

You can increase or decrease the output current by adding or removing 7135 chips, each chip adds or subtracts around .350mA.  I sell these chips as an add on for DIY or offer them pre-installed, ready-to-run, for an additional cost.  See pull down option for cost for this services.   The addition of these services may extend handling time 1-10 days.

 

Features:

*Input voltage: 2.8V - 4.5V

*Current: 1.05A

*Constant current

*PCB diameter: 17mm

*PCB thickness: 1.2mm

*Components height: 1.5mm

*Memory function (sets in after 2 seconds)

*No LED Leads Included

*Reverse polarity protection

*Gold plated contacts

*Low voltage warning: At 2.9-3V the light will blink once per second.

 

Mode groups (default AK-47A firmware):

  1. 3 Mode.  Low-Medium-High
  2. 5 Mode. Low-Medium-High-Strobe

With the default AK-47A firmware, you select mode groups by waiting for the light to blink on the low mode, then turning off the light or pressing the switch directly after the blink.  


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:

  1. 2% - 25% - 100% | Memory
  2. 100% - 25% - 2% | No Memory

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. 


Optional STAR Firmware

This firmware will allow you to fully customise your light!  Moonlight, memory, and mode order are all selectable via solderable stars (see below).

When selecting this option, please define the following in your checkout comments:

  1. Number of light levels:  up to 6 (plus moonlight).
  2. Approximate output levels of each mode.  Example:  (1) 2% - (2) 15% - (3) -  50%  (4) - 100%
  3. Approximate Turbo Timer stepdown time:  15 to 120 seconds.
  4. Mode lock time (on time until mode is memorized):  between 0.5 and 5 seconds.
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 mode memory no memory

 

 

Optional NLITE firmware: 

  • With both mode groups, you can choose whether you would like the mode order to ascend or descend, i.e. L-->M-->H (ascending) or H-->M-->L (descending)
  • You can also choose whether or not your would like mode memory.  If you choose "no memory", the light will always start on either low or high (depending on ascending or descending configuration) after being turned off. 

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.  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
