More info


8-channel module with relays designed to work with the Raspberry Pi Pico. It has built-in power isolation as well
optocouplers that prevent interference from the external high voltage circuit. The module uses high-quality relays with a contact load of up to 10 A at 250 V AC or 30 V DC. The board is closed in a protective casing made of ABS with a bracket for mounting on a rail. The USB port and BOOT pin make it easy to debug without disassembling the case, and the PWR indicator, RGB LED and a passive buzzer on the outside of the case allow you to add a simple indication of the operating status of the device. Full documentation with examples is available on the product wiki page.

The kit does not include the Raspberry Pi Pico. They must be purchased separately.
