The PPC-CM4-156 is full-featured, rugged, designed, and certified for industrial usage, ready to deploy industrial applications based around the Raspberry Pi® Compute Module 4.

The PPC-CM4-156 (PN: CS19108RA4156) 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-CM4-156 features a 15.6” screen with a ten-point capacitive touch panel and offers extensive connectivity such as RS232 and RS485 ports and multiple opto-isolated I/O, Ethernet, USB, WiFi, Bluetooth, and much more.

4G/LTE and ZigBee modules can be added to the product in the optional modules section.

Hardware Features

The PPC-CM4-156 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).

It supports panel, front mount, and VESA mount for different integration applications.

The 15.0” screen with a ten-point capacitive touch and 1920×1080 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, and the PPC-CM4-156 shines on this front. Besides the integrated Ethernet connector supporting up to 1000Mbps and WiFi + BLE wireless module, an optional 4G/LTE and ZigBee modules are available.

Wired connectivity includes also two USB 2.0 Host ports, one mini USB OTG port, and a GPIO connector featuring RS232, RS485, CAN, and Relay. The audio section is also complete with a front panel microphone, a 3.5mm audio connector, two 2W internal stereo speakers, and one internal Buzzer.

The PPC-CM4-156 supports a wide range of input voltages from 12V to 36V DC with a typical power consumption of 17W, featuring a wide range of protection features, allowing it to meet stringent industrial safety regulations.

For a detailed description of the available features refer to the Technical Features table below.

Performances and reliability

The PPC-CM4-156 is powered by the Raspberry Pi CPU, a high-performance Broadcom BCM2711, Quad-core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz application processor.

The Raspberry Pi has been extensively upgraded every time a new model was launched. With the Raspberry Pi 4, the most important upgrades are its faster processor and more RAM. It now also has USB 3 ports, dual HDMI ports with support for 4K output, and faster onboard ethernet.

You can choose the version of CM4 you like as well as include optional modules during the ordering process.

The Raspberry Pi Compute Module 4 is also backed by numerous open-source repositories and examples on GitHub, which makes creating your new industrial solution accessible and straightforward.

Operating system

The Industrial Pi, like other Raspberry Pi® based products, supports the Debian operating system. 

We have developed all the needed drivers, so every hardware feature is readily available for any standard development tool. If your project requires an OS that is not on the list, please contact us, and we’ll make a customized version that suits your needs.

If you need a different OS installed, get in touch with us and we will do it for you.
