Unicorn Flashlight Driver Board, Constant Current Board 700mA 3.8V, Dimensions 17mm, 7135*2, 7135 IC Circuit Board

Unicorn Flashlight Driver Board: Constant-current board, 700mA, 3.8V, 17mm, 7135×2, 7135 IC circuit board. Nichia NCSU033B, NCSU276A, NCSU033C, Seoul 3W, LG 3W – any 0.7A model will work. Please specify which lamp you are using before purchasing.

LED constant-current circuit; the high current makes it particularly suitable for 3W LEDs

Input voltage: 3–6 V

A configuration using two 7135 ICs, each rated at 350 mA, is employed. The output current of the two 7135 ICs is approximately 700 mA.

The PCB has a diameter of approximately 17 mm and is a double-sided gold-plated version of excellent quality.

Suitable for powering with a single lithium battery or 3 AA/4 AA standard batteries

Suitable for use in torches, lighting modifications and similar applications

(Solder the red and black output wires to the driver board; connect the red end of the wire to the positive terminal of the LED and the black end to the negative terminal; connect the inner metal ring on the reverse side to the positive terminal of the battery and the outer metal ring on the reverse side to the negative terminal of the battery.)

This driver board contains a small spring on the positive terminal!
