• PACKAGE: 1 PCS NUBM08 0A 0E 0F forty four 05 07 0C 0G NUGM03 04 06 φ22mm Laser Module Universal Driver Specification (circular plate φ 22mm): Drive board operate description: the round hand plate is in two gears (one instruments highlights, one instruments explodes). Circuit control: adaptive laser voltage high functionality constant current enhance circuit. Boost efficiency: when the voltage is able 4V, the efficiency is greater than 95%, and the 3V voltage is also 86%. All increase circuits at the market. Chip brand: Texas Instruments. Size specification: diameter 22mm. Reverse connection protection: unique opposite connection defense design, using excessive recent MOS to do opposite connection. Quick birth protection: either enter and output have clear out capacitance. Definition of polarity: the circular plate is the tremendous electrode of the spring-connected battery, and the outer ring is the unfavourable electrode of the battery. Power recommendation: 3 rechargeable lithium battery (16340, 18650, 14500 and 18500)
