Introduction to Raspberry Pi Pico W

pico_w_side

Raspberry Pi Pico W brings wireless connectivity to the best-selling Raspberry Pi Pico product line. Built around our RP2040 silicon platform, Pico products bring our signature values of high performance, low cost, and ease of use to the microcontroller space.

Raspberry Pi Pico W offers 2.4GHz 802.11 b/g/n wireless LAN support, with an on-board antenna, and modular compliance certification. It is able to operate in both station and access-point modes. Full access to network functionality is available to both C and MicroPython developers. Raspberry Pi Pico W pairs RP2040 with 2MB of flash memory, and a power supply chip supporting input voltages from 1.8–5.5V. It provides 26 GPIO pins, three of which can function as analogue inputs, on 0.1”-pitch through-hole pads with castellated edges. Raspberry Pi Pico W is available as an individual unit, or in 480-unit reels for automated assembly

Pico’s Pins

pico_pin

Name

Description

Function

GP0-GP28

General-purpose input/output pins

Act as either input or output and have no fixed purpose of their own

GND

0 volts ground

Several GND pins around Pico W to make wiring easier.

RUN

Enables or diables your Pico

Start and stop your Pico W from another microcontroller.

GPxx_ADCx

General-purpose input/output or analog input

Used as an analog input as well as a digital input or output – but not both at the same time.

ADC_VREF

Analog-to-digital converter (ADC) voltage reference

A special input pin which sets a reference voltage for any analog inputs.

AGND

Analog-to-digital converter (ADC) 0 volts ground

A special ground connection for use with the ADC_VREF pin.

3V3(O)

3.3 volts power

A source of 3.3V power, the same voltage your Pico W runs at internally, generated from the VSYS input.

3v3(E)

Enables or disables the power

Switch on or off the 3V3(O) power, can also switches your Pico W off.

VSYS

2-5 volts power

A pin directly connected to your Pico’s internal power supply, which cannot be switched off without also switching Pico W off.

VBUS

5 volts power

A source of 5 V power taken from your Pico’s micro USB port, and used to power hardware which needs more than 3.3 V.
