Description: This is an open-collector driver board designed to small load such as relay, lamp and small unipolar stepping motors. It can drive up to 8 loads. The board uses ULN2803 for a driver. It has 8 open-collector outputs with free wheeling diodes. Outputs are activated by low logic of input signals .This board can drive 2 unipolar stepping motors at the same time.
Features:
- 8 channels open-collector outputs
- 500mA/Channel
- Active low logic
- 2 unipolar stepping motor drivers
Dimensions: 66.7x36.0mm
