This Motor drive module itself comes with our-way L9110S chip module which gives supply voltage of 2.5-12V
Features:
- Suitable motor range: motor working voltage is between 2.5v-12V
- the maximum working current is 0.8A
- the current smart car voltage and current in the market are within this range.4 can drive 4 DC motors at the same time or 2 4-wire 2-phase stepping motors.
