L9110S 4 Channel Drive DC Motor Drive Board Motor Drive Module Smart Car 4-Way Driver
Description
1 The motor drive module itself comes with four L9110S chips.
2 Module power supply voltage: 2.5-12V
3 Suitable motor range: the motor working voltage is between 2.5v-12V and the working current is 0.8A. The voltage and current of the current smart cars on the market are within this range
4 It can drive 4 DC motors at the same time, or 2 4-wire 2-phase stepping motors.
