Pinout

Pin Descriptions

Pin NumberBCM PinPin NameDescription
13GPIO27USER LEDActive HIGH, to switch on the USER LED, the pin's state should be HIGH.
15GPIO22USER BUTTONThis pin normally pulled-down to ground. When the button is pressed, pin switches to LOW.
31GPIO6RIThis pin is Ring indicator functions as the indication for receiving call or SMS, can be calibrated to HIGH or LOW using the AT commands.
33GPIO13DTRWhen the module is in sleep mode, DTR pin allows to wake the module up by pulling it to LOW.
35GPIO19W_DISABLEThis pin is used to turn Airplane Mode on the module, by pulling it HIGH.
37GPIO26HAT_PWR_OFFPower 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.
