KAmodRPI Pico Safe Relay
By: Adam KitaKamodRPI Pico Safe Relay is a module in the form of a shield for Raspberry Pi Pico equipped with four electromagnetic relays with an additional galvanic barrier based on optocouplers and an isolated DC/DC converter powering the relay coils. The board also includes four digital inputs with optocouplers, a set of LEDs signaling the states of inputs and outputs, a RESET button, and a supply voltage indicator. The module will find applications in building automation (including smart home applications), robotics, industrial automation, measurement systems, laboratory installations, and teaching.
