Fanless Raspberry Pi CM4 panel PC features 15.6-inch touchscreen display, supports 9V-36V wide input voltage

EDATEC ED-HMI2320-156C is a fanless panel PC powered by a Raspberry Pi CM4 module with 15.6-inch capacitive touchscreen display and a metal enclosure ensuring cooling that’s built upon the previous Compute Module 4 smart displays from the company such as the 10.1-inch EDATEC ED-HMI2020-101C industrial panel PC and the ED-HMI2120-101C adding features such as 4G LTE, RS232 and RS485, M.2 NVMe SSD.

The company’s latest HMI solution comes with two mSATA sockets, a 4K-capable HDMI 2.1 output port, two Gigabit Ethernet ports, optional WiFi 5, Bluetooth 5, and 4G LTE connectivity, as well as a few USB ports and DB9 serial ports. It can operate in the -25°C to +60°C temperature range and takes 9V to 36V DC input.

As usual, EDATEC supports Raspberry Pi OS Desktop/Lite 32-bit/64-bit with drivers required to support the features of the panel PC. They either provide complete images or a script to configure the stock Raspberry Pi OS image after installation. It’s not the first fanless panel PC based on a Raspberry Pi CM4 module that we covered as the ComfilePi CPi-C070WR4 7-inch panel PC that also looks to be fanless, and we had also written about higher-end Intel-based fanless panel PCs.

EDATEC says the ED-HMI2320-156C model is still undergoing sampling, and they sell one – and exactly one! – sample on Aliexpress for $399 plus shipping. If it’s out of stock you’d have to contact them to find out about availability. Additional information may also be found on the product page.
