This Relay add-on module connects to XIAO and QT Py boards, providing them with switching ability for loads of up to 10A/250VAC. It lets your XIAO control other devices by acting as a switch for devices connected to the terminal blocks. You can also connect and install this with ESPHome in Home Assistant for smart control. Due to the small terminal blocks and open nature of the module, we don't recommend this for mains-powered applications, and suggest you stay well within the max ratings, use ferrules with stranded core wires, and enclose the module in a suitable and safe enclosure.
