5V
Average current
≤120mA
Peak current
800mA
Average power
≤0.6W
Communication level
LVTTL（3.3V）
This product has no overvoltage nor polarity protection, so please make sure that connection and power
supply are normal. The fluctuation of the power supply voltage in a range of ±0.1V is allowable.
Average current varies along with the operating modes of the product in two patterns, more specifically, its
current is around 70mA under short distance mode and it is around 120mA under long distance mode.
Please make sure that the power supply current meets the peak current of 800mA. In case of insufficient
power supply current, the product maybe can’t work normally.
