The Raspberry Pi Pico 2 W with Header is a compact yet powerful microcontroller board built around the new RP2350 microcontroller. It features dual‑core processing — either dual Arm Cortex‑M33 or dual open‑hardware Hazard3 RISC‑V cores — running at up to 150 MHz. Onboard you get 520 KB of SRAM and 4 MB of QSPI flash, giving ample memory for code, data, and wireless firmware. The board brings 2.4 GHz 802.11n Wi‑Fi and Bluetooth 5.2 via its integrated wireless modem and antenna, enabling networked and IoT applications out of the box.

With 26 multifunction 3.3 V GPIO pins (a few of which support ADC), plus support for UART, SPI, I2C, PWM, PIO, and USB 1.1 (host and device), the Pico 2 W offers broad interfacing flexibility for sensors, displays, and peripherals. Supplied with pre‑soldered headers, it’s breadboard‑ and prototype‑ready. Security features — including Arm TrustZone, boot signing (OTP key storage), SHA‑256 acceleration, and hardware mitigations — make it suitable for professional and embedded use. The board also retains full hardware and software compatibility with the earlier Pico series.
