CAN FD LIN Gateway

The CAN-FD LIN Gateway is a user-programmable converter/router/data-logger that features two CAN(/FD) channels, a LIN channel, and a RS-232 port. The converter offers a USB port, microSD card slot and multiple digital/analogue inputs and outputs, and its firmware can be developed in C or C++. The device is suitable for a broad range of applications such as protocol conversion, network bridging, data logging, rest-bus simulation, and external peripheral control and monitoring.

Firmware can be developed in C/C++ and transferred into the device over USB, CAN, RS-232, or a standard ICSP SWD interface, which also offers code debugging. The device is based on a STM32G4 Arm Cortex-M4 MCU and comes with a free-of-charge IDE, GNU C/C++ compiler, and programming examples.

The on-board EEPROM memory can store user’s application parameters, and the microSD card slot enables the user to load or save large data sets for simulations and data-logging purposes.

The four digital outputs (PWM capable) and the two analogue/digital inputs allow for both input and output triggering. The inputs can read 0-5 V analogue signals, and the outputs offer various output stages (push-pull, HSD, LSD) with currents up to 1.5 A enabling to easily control relays, valves, and other peripherals.
