Description The new Raspberry Pi Pico W is a wireless-enabled version of the RP2040-based board, adding 2.4GHz 802.11n WiFi connectivity! The addition of wireless connectivity opens up the Pico W to a vast new range of projects such as remote sensor readings, remote control, home automation, mini web servers, wireless GPIO pin control and much, much more! At the heart of the Pico W is the RP2040 – the same chip used in the original Raspberry Pi Pico, featuring two ARM Cortex-M0 cores clocked at 133MHz; 256KB RAM; 30 GPIO pins; and a broad range of interfacing options. This is paired with 2MB of onboard QSPI Flash memory for code and data storage. WiFi is enabled via the use of an Infineon CYW43439 wireless chip. The CYW43439 supports IEEE 802.11 b/g/n wireless LAN, and Bluetooth 5.2. A Raspberry Pi Pico WH version, with a 40-way header pre-soldered, is also available which has a slightly different board layout (select the WH option above to see the board). With the same footprint and same RP2040 chip, this WiFi Pico can be used as a drop-in replacement for your existing Raspberry Pi Pico projects, upgrading them with WiFi. Just grab a Micro-USB cable (or our handy Pio Essential Kit with a USB cable, headers and more!), install the latest MicroPython Pico W specific U2F file and start programming! The Pico W can be quickly and easily programmed using MicroPython and C/C * using popular editors such as Thonny. Learning how to use the Pico and MicroPython is also very easy thanks to the dedicated Getting Started projects and guide. There’s also a guide for connecting to the internet with the Raspberry Pi Pico W. *Initially, Wi-Fi connectivity will be supported by MicroPython only. Raspberry Pi Pico W Specifications The main chip on board is the RP2040 made by Raspberry Pi (their first in-house microcontroller chip!) and is a dual-core ARM Cortex M0 processor, with a flexible clock running up to 133MHz. WiFi is enabled via the use of an Infineon CYW43439. RP2040 microcontroller chip designed by Raspberry Pi in the United Kingdom Dual-core ARM Cortex M0 processor, flexible clock running up to 133 MHz 264kB of SRAM, and 2MB of onboard Flash memory Infineon CYW43439 wireless chip IEEE 802.11n wireless LAN Bluetooth 5.2 WPA3 SoftAP (up to 4 clients) Onboard antenna licenced from ABRACON (connected via SPI to the RP2040) Castellated module allows soldering directly to carrier boards USB 1.1 Host and Device support Low-power sleep and dormant modes Drag & drop programming using mass storage over USB 26 multi-function GPIO pins 2×SPI, 2×I2C, 2×UART, 3×12-bit ADC, 16×controllable PWM channels Real-time clock (RTC) Temperature sensor Accelerated floating-point libraries on-chip 8×Programmable IO (PIO) state machines for custom peripheral support Dimensions (WxLxH) Pico W: 21mm x 51.3mm x 3.9mm Weight Pico W: 4g Raspberry Pi Pico W Resources Getting Started with Raspberry Pi Pico Raspberry Pi Pico W Pinout Connecting to the internet with the Raspberry Pi Pico W Getting to grips with Bluetooth on Pico W MicroPython UF2 image with networking support Raspberry Pi Pico W Datasheet Raspberry Pi Pico W Product Brief Raspberry Pi Pico W STEP 3D Model Raspberry Pi Pico W Fritzing part Raspberry Pi Pico W Design Files Infineon CYW43439 datasheet Thonny Python IDE Raspberry Pi Pico W Pinout A few RP2040 GPIO pins are used for internal board functions: GPIO29 OP/IP wireless SPI CLK/ADC mode (ADC3) to measure VSYS/3 GPIO25 OP wireless SPI CS – when high also enables GPIO29 ADC pin to read VSYS GPIO24 OP/IP wireless SPI data/IRQ GPIO23 OP wireless power on signal WL_GPIO2 IP VBUS sense – high if VBUS is present, else low WL_GPIO1 OP controls the on-board SMPS power save pin (Section 3.4) WL_GPIO0 OP connected to user LED Apart from GPIO and ground pins, there are seven other pins on the main 40-pin interface: PIN40 VBUS PIN39 VSYS PIN37 3V3_EN PIN36 3V3 PIN35 ADC_VREF PIN33 AGND PIN30 RUN Differences between the original Raspberry Pi Pico and the new Pico W The main changes are: The Pico W includes the wireless Infineon CYW43439 wireless chip The Pico W has a different component layout, including debug pins moved to the middle of the board The onboard LED, Power Supply Mode Select and VBUS Detect pins are now controlled via the wireless LAN chip Package Includes 1 x Raspberry Pi Pico W, RP2040
