KinCony Pi5R32 – Automation IoT Server | Raspberry Pi CM5 32-Channel Relay
Build your own powerful local automation server with the Pi5R32. This compact DIN‑rail controller combines a full Linux computer (Raspberry Pi CM5) with 32 high‑power relays, 32 optocoupler‑isolated digital inputs, 4 analog inputs, 2 PWM outputs, and both RS232 & RS485 serial ports. Perfect for large‑scale smart home automation, building automation, industrial control, and IoT projects that require high‑density I/O control while maintaining the flexibility of a Raspberry Pi platform. As a powerful IoT gateway, the Pi5R32 enables you to run Home Assistant, Node‑RED, or custom Linux applications locally, without relying on cloud services.
-
High‑Density I/O Integration
32× relays (250VAC/7A), 32× isolated digital inputs, 4× analog inputs (0‑5V & 4‑20mA), 2× PWM outputs – ideal for large‑scale automation projects. -
Local Automation Hub
Run Home Assistant, Node‑RED, or Linux software locally without monthly fees or cloud dependency. Your data stays in your home. -
Flexible Storage & Expansion
microSD card slot for Lite modules, plus M.2 PCIe socket for high‑speed NVMe SSDs. -
Serial Connectivity
Built‑in RS232 and RS485 ports for direct communication with legacy industrial equipment, sensors, and actuators.
Among other outstanding features are the following:
- High‑Performance Processing: The Raspberry Pi Compute Module 5 (CM5004000) delivers significantly improved CPU performance compared to previous generations, perfect for demanding automation tasks[reference:10].
- Rich Display & GPIO Options: Includes a full‑size HDMI 2.0 port for monitors, optional GPIO extender provides 20 free pins for custom hardware.
- Industrial Enclosure: Robust aluminum shell with active cooling (heatsink + fan) ensures reliable 24/7 operation.
- 32‑Channel Relay Output: With 32 SPDT relays supporting up to 250VAC/7A or DC30V/7A, the Pi5R32 is ideal for controlling lighting, HVAC, pumps, contactors, motors, and industrial equipment simultaneously.
- Complete Automation Server: Unlike traditional PLCs or relay controllers, Pi5R32 can run Home Assistant, Node-RED, Docker containers, MQTT brokers, and custom Linux applications directly on the device, making it a complete automation server and high-density I/O controller.

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 slot is only available when using a CM5 Lite module.[reference:54]
-
Programming the CM5 via USB‑C: To access the CM5 eMMC or microSD storage through USB‑C:
- Connect the Pi5R32 to your computer using a USB‑C cable.
- Run the Raspberry Pi
rpibootutility. - The eMMC or microSD storage will appear as a removable drive.
- Flash Raspberry Pi OS or other Linux distributions directly.[reference:55]
