Janz Tec’s emPC-A/RPI4 is a device based on a Raspberry Pi Compute Module 4 which is integrated on a self-developed baseboard. Extensive connectivity is guaranteed by USB 2.0 ports, Gigabit Ethernet, a real-time clock, digital inputs and outputs, dual-band wifi, Bluetooth 5.0 and serial interfaces such as CAN or RS232/RS485. A Trusted Platform Module is integrated as standard to increase security. An expansion slot makes it possible to add your missing interfaces with little development effort. For independent wireless communication, the emPC-A/RPI4 is available with an optional LTE module which also includes GNSS.
