Pinout

Pin Descriptions

Pin Number	BCM Pin	Pin Name	Description
13	GPIO27	USER LED	Active HIGH, to switch on the USER LED, the pin's state should be HIGH.
15	GPIO22	USER BUTTON	This pin normally pulled-down to ground. When the button is pressed, pin switches to LOW.
31	GPIO6	RI	This pin is Ring indicator functions as the indication for receiving call or SMS, can be calibrated to HIGH or LOW using the AT commands.
33	GPIO13	DTR	When the module is in sleep mode, DTR pin allows to wake the module up by pulling it to LOW.
35	GPIO19	W_DISABLE	This pin is used to turn Airplane Mode on the module, by pulling it HIGH.
37	GPIO26	HAT_PWR_OFF	Power regulator control. Normally pulled-down, when this pin drove to HIGH, Hat's power will cut off.

LEDs

PWR LED: When the module is powered up, this RED led turns on
USER LED: It is a programmable user-led can be controlled from the GPIO27 of Raspberry Pi for debugging or just fun.
SGNL LED: This BLUE led indicates the status of the connection. When the connection is established and data is being transmitted/received, this led will blink at special intervals. Otherwise, if there is no connection, the led will remain off.

📖 Note

With Telit Module attached to the Base HAT, the Status LED is off by default, It needs to be activated using the following AT commands.
AT#GPIO=1,0,2
AT#SLED=2
AT#SLEDSAV

The Status LED indicates the following states:

Not registered: Always on

Registered in idle: Blinking 1s on and 2s off

Registered in idle with power-saving: Blinking time depends on network condition in order to minimize power consumption

Buttons

User Button: It is a programmable user button that is connected to GPIO22. Reads HIGH by default.
