(1) PinA (S0) hardware selects the working mode, Pin2 (CT) and Pin3 (DR) is the GY-39 module communication interface
S0=1 (default) Serial UART mode, Pin2 is TX, Pin3 is RX, TTL level S0=0 (when connected to GND) MCU_IIC mode, Pin2 is SCL, Pin3 is SDA
(2) PinB (S1) uses only the sensor chip ME280+MAX44009 mode to select whether the MCU participates in data processing
S1=1 (default) MCU+ chip mode, Pin7, Pin8, please do not have any connection S1=0 (when connected to GND) Chip mode only, Pin7 is the chip SCL bus, Pin8 is the chip SDA bus
