وصف
The RS485 HAT from WisdPi is a fully galvanic isolated Serial communication HAT designed for use with the Raspberry Pi. RS485 can be used across large distances, so isolation of the RS485 bus ensures that your Raspberry Pi is fully protected! RS485 is in use in many applications like industrial and home automation (for example MODBUS), lighting control (DMX), video surveillance (for example Pelco D) and many more!
