Raspberry Pi CM5 IoT Gateway for Smart Home & Industrial Automation – KinCony Pi5R16

Product Overview

KinCony Pi5R16 is a powerful Raspberry Pi–based IoT gateway designed for smart home automation and industrial control applications. Built around the Raspberry Pi Compute Module 5 (CM5), it integrates relay outputs, opto-isolated digital inputs, analog inputs, RS232/RS485 communication, PWM outputs, and multiple expansion interfaces into a compact DIN rail aluminum enclosure.

Pi5R16 is ideal for users who want to build local automation systems using platforms such as Home Assistant, Node-RED, MQTT, Modbus, or custom Linux applications.

The CM5 module directly manages all relays, digital inputs, analog inputs, PWM outputs, and serial communication ports, making development and deployment simple and flexible.

Available GPIOs:

GPIO21, GPIO20, GPIO16, GPIO01, GPIO07, GPIO08, GPIO25, GPIO24, GPIO23, GPIO18,
GPIO26, GPIO19, GPIO06, GPIO00, GPIO11, GPIO09, GPIO10, GPIO22, GPIO27, GPIO17

Default CM5 Version

• CM5004000
• RAM: 4GB
• Lite Version
• Without WiFi
• Without Bluetooth

Important Notes

microSD Card Support

If you are using the CM5 eMMC version, the microSD card slot and SSD disk cannot be used.

The microSD card slot and SSD disk only works with CM5 Lite versions.

Flashing Firmware via USB-C

1. Connect the Pi5R16 to your PC using a USB-C cable
2. Run the rpiboot executable on your Windows PC
3. The eMMC or SD card or SSD disk will appear as a removable drive in Windows

This allows you to flash Raspberry Pi OS or other Linux systems directly.
