Monk Makes Pico Controller Relay Board for Raspberry Pi Pico

The Monk Makes Pico Controller is a dedicated four-channel solid-state relay controller board designed for the Raspberry Pi Pico. This powerful and compact accessory unlocks the ability for your Pico to directly control power to a variety of low-voltage DC and AC loads, making it an essential component for automation, robotics, and IoT projects.

Each of the four independent relay outputs is capable of switching loads of up to 2A (peak) at 16V and is safeguarded by a self-resetting polyfuse for enhanced protection against overcurrent conditions. This feature provides peace of mind when controlling lights, small motors, solenoids, or heaters, ensuring your Pico and connected devices remain safe.

A key integrated feature is the crisp monochrome OLED display with a resolution of 128x64 pixels. This display provides a clear interface for monitoring relay status, viewing sensor data, or creating custom user interfaces directly on the board. For intuitive control, the board includes four physical navigation buttons and a dedicated reset button, allowing for manual operation and configuration without needing a separate computer.

Additional onboard amenities include a built-in buzzer for generating audible alerts, tones, or simple sound effects in your projects. The design thoughtfully provides easy access to all the remaining GPIO pins on the Raspberry Pi Pico, ensuring you can connect additional sensors and peripherals without compromise. For secure mounting in enclosures or projects, the board features four M2.5 mounting holes.

Important Safety Note: This controller is only suitable for switching low-voltage DC and AC circuits. It must NOT be connected to domestic mains electricity (110V or 220V AC). The Raspberry Pi Pico is shown for illustration purposes and is not included with the board.
