KinCony Pi5R8 – Raspberry Pi CM5 DIN Rail Relay Controller for Smart Home & Industrial Automation

Product Overview

KinCony Pi5R8 is a powerful Raspberry Pi-based IoT gateway designed for smart home automation and industrial control applications. Powered by the Raspberry Pi Compute Module 5 (CM5), it integrates relay outputs, optocoupler-isolated digital inputs, analog inputs, RS232/RS485 communication interfaces, PWM outputs, and expansion interfaces into a compact DIN rail aluminum enclosure.

The Raspberry Pi CM5 directly manages relay outputs, digital inputs, analog inputs, PWM outputs, and communication interfaces, making it easy to deploy automation solutions using Home Assistant, Node-RED, MQTT, Modbus, Docker, Python, and other Linux-based software.

Pi5R8 is an ideal platform for smart homes, industrial automation, energy management systems, and IoT edge computing applications.

Important Notes

microSD Card Support

If you are using a CM5 module with onboard eMMC storage, the microSD card slot cannot be used.

The microSD card slot is only available when using a CM5 Lite module.

Programming the CM5

To access the CM5 eMMC or microSD storage through USB-C:

1. Connect the Pi5R8 to your computer using a USB-C cable.
2. Run the Raspberry Pi rpiboot utility.
3. The eMMC or microSD storage will appear as a removable drive.
4. Flash Raspberry Pi OS or other Linux distributions directly.
