Hello,
I've looked at the A6 schematic and it doesn't seem the DE/RE pins of the RS485 chip ( MAX13487E) are connected to the ESP32.
Does this mean the A6 can only transmit RS485, or am I missing something obvious?
Thanks in advance,
alex

DE/RE not need to use, MAX13487 will auto control the signal direction. for ESP32 just use RXD,TXD pins is ok.

DE/RE pin just connect together with 10k resistance to Vcc is ok.

ok, only serial port and IIC bus SDA and SCL pins need set by arduino config file firstly.
