4 Electrical Characteristics
Table 3: Major Electrical Parameters of TFmini Plus
Description Parameter value
Supply voltage 5V±0.5V
Average current ≤110mA
Peak current 500mA
Average power 500mW
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 ±0.5V is allowable.
Average current varies along with the operating modes of the product in two patterns, more specifically, its
current is around 50mA under short distance mode and it is around 180mA under long distance mode.
Please make sure that the power supply current meets the peak current of 500mA. In case of insufficient
power supply current, the product maybe can’t work properly.
