Description Standard shield for raspberry pi, 2*20 pin header connector, 4 matched installation holes On board SPI to CAN bus output converter Tested working with our CAN BUS module, or CAN USB module here (version TJA1050). RS-485 data direction default control by transistor automatically on board, but can also control by GPIO IO4 / pin7. On board MCP2551 SPI-CAN converter clocking on 12mhz, and SN65HVD230 CAN BUS transceiver. Output on pinheader and terminal H / L On board Serial UART to RS-485 bus converter Tested and recommanded our RS-485 debug module here. Output on pinheader and terminal A / B Lead out SPI interface and UART interface On board power indicator LED. Use guide for raspberry pi and python please see here. Demo code for customers please see our this git folder.
