This is a "standard" 2 channel relayboard that should be powerd with 5V (4-6V will do).
- Low cost way to control larger voltages and currents.
- Supplied assembled
- On-board switching transistors.
- On-board back EMF protections.
- On-board LED-indicator for power
- On-board LED-indicator for the relay
- 10 amp 250v rated relay. The board is not tested to be used with mains voltages!
