    We have an environmental monitoring system which uses an ESP32 controller. It uses i2c protocol to talk to sensors, which is not working reliably enough in a noisy environment, so we'd like to change to RS485/MODBUS. We already have the RS485 sensors. This project is to update our main board schematic and PCB for RS485, as well as updating the firmware to use the new sensors.
