Yes, this was a custom board I designed for the NWS ASOS program. We are using it for a translator to connect a Vaisala HMP-155E to the ASOS. The original ASOS is RS-232 over fiber and we aren’t able to change the source code any longer. So adding a new sensor required me to make the HMP-155E talk to our system like it was a different sensor. Taking in the RS-485 data stream from the sensor and reformatting that data to report as an older TSL 1088 unit.
The Rpi Pico only has 2 uarts but it also has serialPIO ports than can be configured to run many different peripherals
