The 3V Relay HAT is a compact two-channel relay board designed specifically for the Raspberry Pi Pico. The board can switch up to 2A/120VAC and 2A/24VDC (maximum) with an operating voltage of 3.3V. Indication LEDs are included on the board to indicate relay on/off status. Assembly is simple - connect your external components to the pre-soldered terminal blocks and slot your Raspberry Pi Pico into the pre-soldered female headers. A Raspberry Pi Pico is not included - click here if you'd like to buy one. Your Pico will need to have male headers soldered to it with the pins pointing downwards (or grab one of our pre-soldered Picos).
