1 The motor drive module itself comes with four L9110S chips.
2 module supply voltage: 2.5-12V
3 Suitable motor range: motor working voltage is between 2.5v-12V, maximum working current is 0.8A, the current smart car voltage and current in 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.
