WebFeb 25, 2024 · 1 Answer. It doesn't matter as even if you're using a USART (which provides an additional CLK pin for synchronous operation) you'll only be using the UART part … The signal level used during the RS485 communication method typically ranges from -7V to +12V. The microcontroller pins are generally not designed to handle these levels. This is why these signals needs to be converted to low voltages, for eg ±3V.
