Figure 2. The pinout of
the Pico W Rev3 board
Raspberry Pi Pico W uses an on-board buck-boost SMPS which is able to generate the required 3.3V (to power RP2040
and external circuitry) from a wide range of input voltages (~1.8 to 5.5V). This allows significant flexibility in powering
the unit from various sources, such as a single lithium-ion cell, or three AA cells in series. Battery chargers can also be
very easily integrated with the Pico W powerchain.
Reprogramming the Pico W flash can be done using USB (simply drag and drop a file onto the Pico W, which appears as
a mass storage device), or the standard serial wire debug (SWD) port can reset the system and load and run code
without any button presses. The SWD port can also be used to interactively debug code running on the RP2040.
Getting started with Pico W
The Getting started with Raspberry Pi Pico book walks through loading programs onto the board, and
shows how to install the C/C++ SDK and build the example C programs. See the Raspberry Pi Pico
Python SDK book to get started with MicroPython, which is the fastest way to get code running on Pico
W.
1.1. Raspberry Pi Pico W design files
The source design files, including the schematic and PCB layout, are made available openly except for the antenna. The
Niche™ antenna is an Abracon/Proant patented antenna technology. Please contact [e-mail] for
information on licensing.
Schematic The schematic is reproduced in Appendix B. The schematic is also distributed alongside the
layout files.
Layout The CAD files, including PCB layout, can be found here. Note that Pico W was designed in
Cadence Allegro PCB Editor, and opening in other PCB CAD packages will require an import script
or plugin.
