Arduino UNO SPE Shield adds Single Pair Ethernet (SPE) and RS485 to Arduino UNO and compatible boards, notably the Arduino UNO R4, via a Microchip LAN8651 SPE controller. Single Pair Ethernet relies ...

Arduino/ESP32 UART TTL to RS485 converter. I'm using the MAX485 JXCT 5 pronged NPK sensor The SoftwareSerial library by Peter Lerup and Dirk O. Kaar ...

From my experience it is absolutely needed to have an Arduino Mega or equivalent (needs to have at least 2 serial ports), you won't be able to read the Modbus if Serial is also used by USB Serial ...

Arduino announced a single-pair Ethernet adapter board for its Uno R4 single-board microcontroller at Electronica this morning. Microchip participated in the development – its LAN8651B1T-E/LMX single ...

What doesn’t this Arduino Mega shield have? Ponder that as you realize that it doesn’t just attach itself to the pin headers, but uses every single one of the mega’s connections. This isn’t a bunch of ...
