The PPC-CM4-236 (PN: CS19108RA4236) is a high-quality industrial PC powered by the Raspberry Pi Compute Module 4 (Quad Cortex®-A72 processor at 1.5GHz clock). It comes with a Raspberry Pi Compute Module 4 of your choice.

Its form factor and metal enclosure with IP65 protection on the front panel make it ideal for intensive industrial applications that require a human-machine interface.

The PPC-CM4-236 features a 23.6” screen with a ten-point capacitive touch panel and offers extensive connectivity options such as USB, RS232, and RS485 ports, Ethernet, and multiple optoisolated I/O.

The WiFi/BT module depends on the CM4 version, while the 4G and ZigBee modules are optional and can be added to the product in the optional modules section. HDMI and SATA II are not supported.


Hardware description

The PPC-CM4-236 is designed for industrial usage, ready to deploy applications based on the Raspberry Pi Compute Module 4 (Quad Cortex®-A72 processor at 1.5GHz clock).

The 23.6” screen with a ten-point capacitive touch and 1920 x 1080 pixel resolution at 400 NIT brightness make this interaction stable with excellent image clarity. It is durable and resistant to environmental contaminants like dust and water.

Wireless connectivity is a must nowadays. The Ethernet connector supporting up to 1000Mbps is integrated, while the availability of the WiFi + BLE module depends on the CM4 selected. The 4G/LTE and ZigBee modules are optional and can be added while ordering.

Wired connectivity also includes two USB 3.0, a USB-C connector OTG port, a Giga-Ethernet, and an extension connector (featuring RS232, RS485, CAN, GPIO). The audio section also has a front panel microphone, a 3.5mm audio connector, two 2W internal stereo speakers, and one internal Buzzer.

Raspberry Pi OS

All Raspberry Pi-based products come with the latest version of Raspberry Pi OS already installed. For specific models, such as the AIO-CM4-101 and the AIO-CM4-156, it is also possible to choose Android 13 or Ubuntu 20.04 as preinstalled OS.

We’ve taken care of all the necessary drivers, so you can easily access every hardware feature using any standard development tool. In the event that your project requires an OS that is not on the list, feel free to reach out to us, and we’ll create a customized version that meets your specific needs.

Raspberry Pi Compute Module 4

This IPC core is the Raspberry Pi CM4, powered by a high-performance Broadcom BCM2711 (RPi 4) application processor.

The BCM2711 has the quad-core CPU design of the BCM2837 but uses the more powerful ARM A72 core. It has a greatly improved GPU feature set with much faster input/output. It is also capable of addressing more memory.

The BCM2711 chip continues to use the heat-spreading technology that started with the BCM2837B0, which provides better thermal management.
