mdot and modbus 485 support

[sabrine]

Hello,

Can I connect the mdot directly to a modbus Sensor?
or do I need an extra module like Max485 like for arduino Uno in this link

Thanks!
Best regards,
Sabrina

Sabrine,

I don’t see any reference to RS485 or modbus in the STM32F411RE reference guide or datasheet, so I don’t think the UARTS on the processor natively support it. You might be able to implement it in software if you really really wanted to.

Your best bet is probably to use an external RS485 transceiver.

Cheers,

Mike
