The Raspberry Pi Pico 1591B Relay Board is an all-in-one two channel relay module and DC power converter for the Raspberry Pi Pico and Pico W. This board allows the Pico to operate within a 12V system and switch higher voltage / higher current devices from a compact, easy to mount, package.

The Pico 1591B Relay Board is compatible with both the Raspberry Pi Pico W and the standard Raspberry Pi Pico making it ideal for IoT applications or automation projects. The board uses GPIO pins 2 and 3 to control the two relays, but breaks out all additional pins in easy to access 0.100” / 2.54mm breadboard pitch through holes. To further extend functionality, we have also included a Qwiic / STEMMA QT connector, allowing any compatible breakout board or sensor to connect to the board.

The Pico 1591B Relay Board is designed to fit in a standard Hammond 1591B enclosure. Power is supplied through the two pin screw terminal, while Common, Normally Open, and Normally Closed relay contacts are brought out for each of the relays in the 6 pin screw terminal. The Raspberry Pi Pico is connected using the castellated edges along the Pico, these are easily soldered with a conventional soldering iron.
