The Industrial Raspberry Pi Forum

Dear Kunbus,

What is the maximum baud rate that we can run the RS485 port on the Revolution Pi Connect+? Use-case is querying a load cell at the highest possible data rate we can achieve.

How is the RS485 port connected inside the Revolution Pi? Custom hardware, or one of the Raspberry Pi UARTs? I seem to recall that the Raspberry Pi 3 has two UARTs; a hardware one and a software one. The hardware one can supposedly run at much higher data rates than the other.

Any suggestions?

Hello Kees Jan,
Thank you for your Inquiry.
You can find the Circuit Diagramm of the revpi connect + to know how the RS-485 is connected inside it.
The standard value of the Baud rate is 19200. No threshold is defined for the RS485. You must proceed randomly to define the maximum Baud rate threshold that suits you.
