DREADME.rst1 .. zephyr:code-sample:: modbus-rtu-client
3 :relevant-api: modbus
16 This sample has been tested with the nRF52840-DK and FRDM-K64F boards,
20 with another board running the :zephyr:code-sample:`modbus-rtu-server` sample.
22 In addition to the evaluation board a RS-485 shield may be used.
23 The shield converts UART TX, RX signals to RS-485.
24 An Arduino header compatible shield like `joy-it RS-485 shield for Arduino`_
26 on the JOY-IT shield. For other shields, ``de-gpios`` property must be adapted
30 The A+, B- lines of the RS-485 shields should be connected together.
