Pinout

Pin Descriptions

Pin Number	BCM Pin	Pin Name	Description
1,2	GP0, GP1	UART	It is connected to the UART pins of the BG95 module and is used for UART communication.
26	GP20	Status	It indicates the on/off status of the BG95 module. The pin is in the LOW position when the module is turned on.
22	GP17	PowerKey	When this pin toggles from LOW to HIGH for a second the module will turn on if it was off and vice versa.
31	GP26	Power	By default, it is in the LOW position, supplying power to the module. If set to HIGH, the module's power is cut off.
16,17	GP12, GP13	Qwiic I2C	The two parallel-connected Qwiic sockets on the Pico LTE are connected to these pins for I2C communication.
7, 21, 24, 25	GP5,GP16, GP18,GP19	SPI	External access is provided to the SPI pins on the Pico LTE.
20	GP15	NeoPixel LED	The NeoPixel LED is controlled using this pin.
27	GP21	User Button	This pin is pulled to the default HIGH state. When the button is pressed, the pin is pulled to the LOW.
29	GP22	User LED	When the pin is pulled HIGH, the LED lights up.
30	RUN	Pico W Reset	This pin is connected to the RESET button. When the button is pressed, it resets the Raspberry Pi Pico W.

Dimension

Power

Rated input voltage(V): 5V DC
Rated input current(A): Max. 1.5A (When no sensor is connected)

The main power input for the Pico LTE board is the Micro USB connector located on the Pico W. It is designed to receive power only through these USB sockets and does not have any other power input ports.

LEDs

USER LED: It is a programmable user-LED that can be controlled from the GP22 of Raspberry Pi for debugging or just fun.
POWER LED: When power is supplied to the Pico LTE board through the micro USB input, the Power LED lights up.
STATUS LED: It indicates the status of the LTE module. The following statuses are indicated based on the blinking pattern:

Logic Level Changes	Network Status
Flicker slowly (200 ms High/1800 ms Low)	Network searching
Flicker slowly (1800 ms High/200 ms Low)	Idle
Flicker quickly (125 ms High/125 ms Low)	Data transfer is ongoing

Buttons

User Button: It is a programmable user button that is connected to GP21. It reads HIGH by default.
PWRKEY Button: To power on/off the LTE module, press and release the button for 1 second.
MBOOT Button: Force the module into emergency download mode.
RESET Button: Reset Raspberry Pi Pico W when pressed.

GNSS

Pico LTE includes a fully integrated global navigation satellite system solution that supports GPS, GLONASS, BDS, Galileo and QZSS.

By default, LTE Module GNSS engine is switched off. It has to be switched on via AT command. The module does not support concurrent operation of WWAN and GNSS. For more details about GNSS engine technology and configurations, see this document.

The Pico LTE board is designed to work only with a passive GNSS antenna. Please use only a passive GNSS antenna and note that the kit does not include a GNSS antenna.
