Description
The second version of our popular USB 4 Relay Board with several improvements. It comes with MCP2200 chipset, 4 SPDT Relays each rated with up to 10A, relays states saving in internal EEPROM and improved USB interference resistance. Suitable for home automation applications, hobby projects, industrial automation. The free DRM software allows to control relays manually, create timers (weekly and calendar) and multi-vibrators, use date and time for alarms or control from command line. We provide various software examples.

Chipset
The relay board chipset is MCP2200. We decided to develop such relay board because as per our tests MCP2200 has some more advantages with other USB-UART chips and one of them is that it is more reliable against USB interference and this is critical on every USB relay board.
The four relays are mapped in the following way with MCP2200 i/o lines:
- Relay1 -> GP0
- Relay2 -> GP1
- Relay3 -> GP2
- Relay4 -> GP3
The four I/O lines are mapped in the following way:
- In1 -> GP4
- In2 -> GP5
- In3 -> GP6
- In4 -> GP7
