HW-249 L9110S four way dc motor drive module

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.
