The WAVESHARE 20218 is an industrial-grade relay module for the raspberry pi pico. This module has 8 channels and carries measures to protect the Raspberry Pi inside and avoid malfunction.
Notes: Raspberry Pi Pico is NOT included.
Features
- Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
- Onboard photocoupler isolation, prevent interference from external high-voltage circuit connected to the relay
- High-quality relay, contact rating: 10A 250V AC or ≤10A 30V DC
- ABS protection enclosure with rail-mount support, easy to install, safe to use
- Breakout USB port and BOOT pin, make it easy to debug without disassembling the enclosure
- PWR indicator, RGB LED, and passive buzzer outside the enclosure
- Comes with development resources and manual (Raspberry Pi Pico C/C++ and MicroPython examples)
Specifications
- Operating voltage: 5V
- Communication Protocol: USB
- Communication interface: Micro USB
