CAN-BUS Module with integrated Optically Isolated Relay

This device is meant to be connected via CAN-BUS to the LoRa-Can module, for use as a remote control and input node. I tried to keep the board as small and compact as possible, and as the intended use requires only one relay, I have only added that. It is however perfectly possible to integrate additional relays and or inputs via the GPIO Pins broken out already. The device uses the ATMEGA328P as its main MCU, but it is also possible to use the ATMEGA8a in its place for a device with lower cost, but also less memory and ram. PCBWay did an excellent job with the manufacturing, as everything is exactly as per the design. Thank you
