- Onboard LEDs for indicating relays status
- Relay control jumper, allows to control the relays by custom pins other than the default pins
- Comes with development resources, including examples in wiringPi, WebioPi, shell, python, and bcm2835

### Schematic

1. Raspberry Pi GPIO interface: for connecting Raspberry Pi
2. Relay screw terminal: for connecting target devices
3. Relays
4. Photocoupler: PC817
5. Relay indicator

- LED on: relay NC is opened, NO is closed
- LED off: relay NC is closed, NO is opened

7. Power indicator
8. Relay control jumper
- short the jumper: control the relays by default I/Os used in the example code
- open the jumper: control the relays by custom I/Os through jumper wires
