Wave RS485 HAT For Pi
The RS485 CAN HAT will enables your Pi to communicate with other devices stably in long-distance via RS485/CAN functions. The HAT is compatible with all the Raspberry Pi's (Zero, Zero W, Zero WH, 2B, 3B, 3B+), the onboard CAN controller MCP2515 via SPI interface, with transceiver SN65HVD230. The RS485 function, controlled via UART, half-duplex communication, with transceiver SP3485 and has reserved control pins, which allows it to work with other control boards.
