GPIO Pinout

The SW inputs are connected via AiP4052 multiplexers (compatible with other 4052 chips). The multiplexer select lines S0 and S1 are connected to GPIO0 and GPIO2 respectively. There are two multiplexers present on the board, it’s possible the other one might be used for the ADC to scan current sensors.

Pin	Condition	Function
GPIO0	-	Mux Select S0
GPIO2	-	Mux Select S1
GPIO12	-	PWM2
GPIO13	-	PWM1
GPIO14	-	PWM3
GPIO16	-	PWM4
GPIO17	-	PWM5
?	?	NTC Temp Sensor
?	?	Voltage Monitor
?	?	Wi-Fi LED
GPIO35	-	Reset Button
GPIO36	GPIO0=1, GPIO2=0	SW4
GPIO36	GPIO0=0, GPIO2=1	SW1
GPIO37	GPIO0=0, GPIO2=1	SW2
GPIO38	GPIO0=0, GPIO2=1	SW3
GPIO39	GPIO0=0, GPIO2=1	SW5

Pro addon interface

Use it for flashing. Connect GPIO0 to GND during reset. Do not connect +12V pin (neither +12V power to other connectors).

Ethernet Interface

The Shelly Pro RGBWW PM has an 8720 ethernet module.
