LED driver board 950mA NJG-15 (19 modes)  $5.00 

Description

NANJG-15 LED driver board for flashlights with 3 selectable groups of light output modes and memory. This is a very efficient board using three 7135 LED Power driver current regulating IC's driving up to 1 amp to the emitter.  The board has low voltage cut off and remembers which mode it was in each time it is powered on. Very low profile. We use this board with a single Rechargeable Lithium-Ion battery to drive CREE, and SSC emitters.

The NANJG-15 LED driver boards have a microprocessor onboard which is programmed at the factory to control the modes. This board has been programmed for three groups of selectable output modes.

The board has low voltage cut off and remembers which mode it was in each time it is powered on. Very low profile. We use this board with a single Rechargeable Lithium-Ion battery to drive CREE, and SSC emitters.

This is a very versatile driver board with three groups of modes. See below for instructions on selecting mode groups. This board features the simple (Low/Medium/High) 3 level group without any strobe or blink. You can also change the mode group to include strobe and blink if desired.

Changing output modes: Modes are switched such as (Low --> Medium --> High --> REPEAT) by momentarily interrupting the power with in 2 seconds of powering on the light. Immediately after turning the light on, tap the power switch to quickly interrupt the power, this will signal the microprocessor on the driver board to change output modes. Modes are remembered if the power is left off for more than two seconds. If the light has been powered ON for more than two seconds, modes can be changed by either turning off the light first or by double tapping the power switch.

Changing Mode Groups: Mode Groups are changed by turning the light on, selecting the Low Mode and after about 4 seconds the light will blink, at this time, turn the flashlight off and wait 5 seconds. When you turn the light back on it will be in the next group of modes.

Features:

  • Regulated current output levels: (High: 950mA/MED: 300mA/Low: 120mA)
  • Three groups of output modes
  • Selectable (Low/Med/High) group without flash or strobe
  • Accepts 2.9 - 6 volts input (operates best over 3.5v)
  • Diameter: 17mm
  • Thickness of board: 1.2mm
  • Total thickness: 3mm
  • Gold Plated for low resistance
  • Low voltage cut-off at 2.6V with 0.08mA

Notes:

This board does not have reverse input diode protection to protect against batteries being installed backward. 

It is very important to have good electrically conductive paths for the driver board to avoid flicker and poor performance. Ensure your pill (A.K.A. sandwich, module....) has a solid path from the negative input of the board to the body of the light; ensure that the threads of the flashlight body also provide a good conducting path. Ground problems are a common issue and a poor installation will result in poor performance!

The board comes with leads which are not pre-attached, if you would like them pre-attached please select this option below.
