MAX485 to lora radio node

LoRa Basics™
#1

I want to connect a sensor to this lora board (RoLa Lora Radio Node containing Atmega328P as microcontroller) through MAX485 to transfer a RS485 data from a soil sensor. The sensor seems remains unconnected if i use pins D5-D8 or D3-D4. The D2 pin already used by the Lora 1278. When I use an Esp32 or Arduino Nano the sensor and MAX485 works

Hi @ahmedriazku,
Please contact your RS485 sensor vendor to get support on it, but did you checked that you are using the correct RS485 address and RS485 protocol (ASCII vs RTU) ?
