KinCony Pi5M32 – Automation IoT Server | Raspberry Pi CM5 32-Channel MOSFET
Build your own powerful local automation server with the Pi5M32. This compact DIN‑rail controller combines a full Linux computer (Raspberry Pi CM5) with 32 high‑current MOSFET outputs, 32 optocoupler‑isolated digital inputs, 4 analog inputs, 2 PWM outputs, and both RS232 & RS485 serial ports. Unlike traditional relay controllers, the Pi5M32 uses solid‑state MOSFET outputs rated at 2A per channel, making it ideal for PWM dimming, DC motor control, solenoid valves, LED lighting, and industrial actuators. As a powerful IoT gateway, the Pi5M32 enables you to run Home Assistant, Node‑RED, or custom Linux applications locally, without relying on cloud services.
-
Solid‑State MOSFET Outputs
32× MOSFET channels, 2A per channel (continuous) – ideal for DC loads: LED strips, solenoid valves, DC motors, relays, and industrial actuators. -
All‑in‑One I/O Integration
32× isolated digital inputs, 4× analog inputs (0‑5V & 4‑20mA), 2× PWM outputs – no extra modules needed. -
Local Automation Hub
Run Home Assistant, Node‑RED, or Linux software locally without monthly fees or cloud dependency. Your data stays in your home. -
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.
- 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.
- MOSFET vs. Relay: Unlike mechanical relays, MOSFET outputs provide silent, fast switching with no moving parts – ideal for PWM dimming, high‑frequency switching, and applications requiring long service life.
- Complete Automation Server: Pi5M32 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 DC output 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.
-
Programming the CM5 via USB‑C: To access the CM5 eMMC or microSD storage through USB‑C:
- Connect the Pi5M32 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.
