1AA 3W LED MCU Circuit Board (0.8V-7V)

Ref:SL191

Item includes:
1 x circuit
2 x wiring

Dimensions:
17mm in diameter, 3mm total thickness, 1.2mm circuit board thickness, input spring and output needle is gold plated

Factory output voltage is selected as 3.5V-3.7V, select output voltage using a small "cross" screw driver by turning the voltage selection screw at the bottom of the circuit board

Output explained:
1) 1AA: Maximum output (3W) can be obtained by setting the output voltage at 3.5-4V. Maximum current output can reach 700mA with 3A of input from a fully charged NiMH Sanyo 2700mAh AA cell
2) 2AA: Output voltage select to 3.5v-3.7v
3) For Luxenon 5W, set selected output voltage to 6V-7V (no load) using one Li-ion cell
4) For Luxenon new K2, set selected output voltage to 4V-4.5V using one Li-ion cell, output current will be > 2A

1) Low, Med, High, Strobe, SOS
2) Low, Med, High, Police Strobe, SOS
3) Low, Med, High, Police Strobe, Slow strobe (3HZ), Extreme slow strobe (1HZ), SOS
 
Two seconds light memory.
At any low light mode, LED will flash at about 4-5 second interval, switch off the flashlight to switch to the next main-light-modes.

MCU light mode selection:

(Notes: Two AA is workable with this 3W step-up voltage circuit board. Select the output selector to 3.5v-3.7v when using two AA setup.)

Input voltage: 0.8-7v <= output selected voltage, maximum input/ouput current at 3A, output voltage selectable from 2V-7V

We supply most of flashlights accessories such as circuit, reflector, LED, lens and can customized them according to your need
