Pigeon RB700 is a computer designed for use in industrial control and automation systems. Pigeon RB700 is powered by Raspberry Pi Compute Module 4 and Linux system. RB700 model is available in three versions: ESSENCE, STANDARD and ADVANCE. The ADVANCE version, compared to the STANDARD version, has two M.2 connectors and two additional RS-232 ports. M.2 connectors allow mounting a modem with support for dual SIM and SSD disk or any other module that supports PCIe 2.0. Built-in UPS based on supercapacitors ensures elimination of short power interruptions and safe system shutdown. The UPS is controlled by the microcontroller, which ensures the restart of the system in the event of the return of the power supply. All versions have the following interfaces: two RS-485, two Ethernet, CAN, 1-WIRE, RS-232, 12 digital inputs (8 opto-isolated, 4 dry contact) and 8 digital outputs.
