16 This sample has been tested with the nRF52840-DK and FRDM-K64F boards,
26 Using RS-485 transceiver
30 In addition to the evaluation board, an USB to RS-485 bus adapter and
31 a RS-485 shield are required. The shield converts UART TX, RX signals to RS-485.
32 An Arduino header compatible shield like `joy-it RS-485 shield for Arduino`_
34 on the JOY-IT shield. For other shields, ``de-gpios`` property must be adapted
38 The USB to RS-485 adapter connects to the USB port of a computer.
39 The two A+, B- lines should be connected to the RS-485 shield.
