Raspberry Pi Pico W offers a minimal but flexible external circuit to support the RP2040 chip: flash memory (Winbond W25Q16JV), a quartz crystal, power supplies and decoupling, as well as a USB port. The majority of RP2040 microcontroller pins are brought to the user IO pins on the left and right edges of the board. Four RP2040 I/O pins are used for internal functions: controlling an LED, integrated switch-mode power supply (SMPS) power control, and capturing system voltages.
Pico W features a built-in wireless 2.4GHz interface with an Infineon CYW43439. The antenna is a board antenna licensed by ABRACON (formerly ProAnt). The wireless interface is connected to the RP2040 via SPI.
Pico W is designed to use either soldered 0.1-inch pin headers (it is 0.1-inch wider than a standard 40-pin DIP package) or positioned as a surface-mount 'module' since the user I/O pins are also broken out. There are SMT pads under the USB port and BOOTSEL button, allowing access to these signals when used as a reflow-soldered SMT module.
Raspberry Pi Pico W uses an integrated buck-boost SMPS that can generate the required 3.3V (for powering the RP2040 and external circuits) from a wide range of input voltages (~1.8 to 5.5V). This provides significant flexibility in powering the device from various sources, such as a single lithium-ion cell or three AA cells in series. Chargers can also be easily integrated into the Pico W power chain.
Reprogramming Pico W's flash can be done via USB (simply drag and drop a file onto the Pico W, which appears as a mass storage device) or the standard SWD (Serial Wire Debug) port can reset the system and load and execute code without pressing any buttons. The SWD port can also be used for interactive debugging of code running on the RP2040.

What's on your Pico?
If you forget what was programmed into your Raspberry Pi Pico, and the program was built using our Pico C/C++ SDK, usually a name and other useful information is embedded into the binary. You can use the Picotool command-line program to find out these details. Detailed instructions on using Picotool can be found in our documentation
