Utilise the Raspberry Pi Pico in industrial or home automation environments with this robust Industrial 8-Channel Relay Module!

This module provides 8 relay channels which can each switch up to 10A 250VAC or 10A 30V DC max. The module offers safety in the form of onboard unibody power supply isolation combined with photocoupler isolation to prevent interference. The custom ABS enclosure protects both user and hardware, and provides DIN and screw mounting options.

Your Raspberry Pi Pico slots into the dedicated female headers and is programmed via the micro-USB port on the side of the board (connected to the Pico via Pogo pins) which is accessible once the enclosure is assembled. A handy boot and rest button are also found here, alongside a programmable buzzer, RGB LED and power LED.

Each relay also has its own LED indicator, showing the status of the relay.

Note: Raspberry Pi Pico not included. You'll need a Pico with male headers soldered to it. You can grab a Pico here and Pico male headers here, or buy a Pico with pre-soldered headers.

Industrial 8-Channel Relay Module for Raspberry Pi Pico
Satisfyingly clicks into action once you interface with the pins. I've got this working with a Pi 3b+ even though it's designed to work with a Pico

Industrial 8-Channel Relay Module for Raspberry Pi Pico
Well made product. but documentation is sketchy and example code is for the brave: requires some careful reading and modification. I wanted to control the relays over USB from another system (rPi 4) and it turns out that the C code on https://www.waveshare.com/pico-relay-b.htm lets you do that, writing from the host over the serial port. I can "echo -nr "\x04" > /dev/serialetcetcetcetc and lo and behold relay 4 switches on!

8 Channels are likely overkill for many people, but if you have the need, the form factor of this relay is really convenient.

This is a great product, coming from a Pico. If you are looking for home automation, this is perfect. You can control up to 8 channels from a single Pico.
