Running at 150MHz with either dual ARM Cortex-M33 or dual RISC-V Hazard3 cores — selectable per application — it delivers significantly more raw compute than the RP2040-based Pico W while maintaining full hardware and software compatibility with the existing Pico ecosystem. The board pairs 520KB of on-chip SRAM with 4MB of QSPI flash and exposes 26 multi-purpose GPIO pins, four of which can be used as ADC inputs. Two UARTs, two SPI controllers, two I2C buses, 24 PWM channels, and 12 PIO state machines provide rich peripheral coverage for embedded applications. Power input is flexible at 1.8–5.5V, and the USB 1.1 controller supports both host and device operation. Wireless connectivity is provided by the Infineon CYW43439, supporting 2.4GHz single-band 802.11n (WiFi 4) with WPA3 security and Bluetooth 5.2 Classic plus BLE. The CYW43439 shares the SPI bus with the RP2350, a design that is fully documented and open-source. Security is enhanced by the RP2350's hardware True Random Number Generator, SHA-256 accelerator, and an optional secure boot chain. The Pico 2W is programmable in C/C++ via the official Raspberry Pi Pico SDK, MicroPython, and CircuitPython. It is pin-compatible with the original Pico W, allowing existing Pico W projects to benefit from the RP2350's higher performance and larger memory with minimal code changes. ## Where to Buy - [Adafruit](https://openhardware.directory/r?to=https%3A%2F%2Fwww.adafruit.com%2Fproduct%2F6087&ref=openhardware.directory&product=raspberry-pi-pico-2w&source=md-export) — $7.00 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fwww.raspberrypi.com%2Fproducts%2Fraspberry-pi-pico-2w%2F&ref=openhardware.directory&product=raspberry-pi-pico-2w&source=md-export) - [github](https://openhardware.directory/r?to=https%3A%2F%2Fgithub.com%2Fraspberrypi%2Fpico-sdk&ref=openhardware.directory&product=raspberry-pi-pico-2w&source=md-export) - [datasheet](https://openhardware.directory/r?to=https%3A%2F%2Fdatasheets.raspberrypi.com%2Frp2350%2Frp2350-datasheet.pdf&ref=openhardware.directory&product=raspberry-pi-pico-2w&source=md-export) - [schematics](https://openhardware.directory/r?to=https%3A%2F%2Fdatasheets.raspberrypi.com%2Fpicow%2FPicoW-A4-Pinout.pdf&ref=openhardware.directory&product=raspberry-pi-pico-2w&source=md-export) - [wiki](https://openhardware.directory/r?to=https%3A%2F%2Fwww.raspberrypi.com%2Fdocumentation%2Fmicrocontrollers%2Fpico-series.html&ref=openhardware.directory&product=raspberry-pi-pico-2w&source=md-export) ## Tags `raspberry-pi`, `pico`, `rp2350`, `microcontroller`, `wifi`, `bluetooth`, `circuitpython`, `micropython`, `ble`, `wpa3` ## Images ![Raspberry Pi Pico 2W](https://nbg1.your-objectstorage.com/openhardware-directory/entities/raspberry-pi-pico-2w/1047ca238cbe.jpg) ![Raspberry Pi Pico 2W](https://nbg1.your-objectstorage.com/openhardware-directory/entities/raspberry-pi-pico-2w/ef76764cccbb.jpg) ![Raspberry Pi Pico 2W](https://nbg1.your-objectstorage.com/openhardware-directory/entities/raspberry-pi-pico-2w/9fff7758d0b0.jpg) --- [View full device page](https://openhardware.directory/devices/raspberry-pi-pico-2w)
