We’re covered DIN-Rail industrial computers powered by Raspberry Pi CM4 module, but Kristech’s Pigeon RB700 automation controller may be the one with the most features so far thanks to two RS-485 ports, two Ethernet ports, CAN FD, 1-WIRE, RS-232, 12 digital inputs (8 optoisolated, 4 dry contacts), and 8 digital outputs.

That’s for the common features present in all variants including RB700 Essense. The RB700 Standard model adds UPS, HDMI, analog I/Os, and TPM, while the RB700 Advance is further equipped with two M.2 sockets (for SSD and/or cellular modem) and two additional RS-232 ports.

The company provides a lightweight Linux distribution based on the official Raspberry Pi OS (Lite?) plus the code/drivers to handle the extra interfaces. Kristech also says the system supports “open-source and commercial software for automation and control systems” such as the company’s PigeonTool, as well as openHAB, Domoticz, PiDome, CODESYS, and REX Control System.

You’ll find what appears decent hardware and software documentation on the company’s website, as well as code samples in C, Python, and Bash on Github, some of which are several years old and designed for their earlier Raspberry Pi CM3 models.

Poland-based Kristech did not provide pricing for their industrial controllers. More details may be found in the announcement and products pages.
