Raspberry Pi Pico 2 W (RP2350 Wireless Microcontroller Board)

The Pico line's wireless upgrade

The Raspberry Pi Pico 2 W builds on the original Pico W by moving to the newer RP2350 chip, which brings a higher core clock speed, double the on-chip SRAM and double the on-board flash memory compared to its predecessor. The chip is unusual in offering a choice of core architecture: it can run as dual Arm Cortex-M33 processors or dual RISC-V Hazard3 processors, both clocked at 150MHz, giving developers flexibility depending on which toolchain or instruction set they prefer to target.

Memory is generous for a microcontroller board of this size: 520KB of on-chip SRAM and 4MB of onboard QSPI flash, comfortably ahead of most boards in its class and enough headroom for larger applications, buffered sensor data or a more complete networking stack.

Wireless, security and I/O

Wireless connectivity covers 2.4GHz 802.11n WiFi and Bluetooth 5.2, built directly onto the board, so no separate module is needed for network-connected projects. On the security side, the RP2350 adds TrustZone and secure boot support, features aimed at products that need to protect their firmware from tampering, which the original RP2040-based Pico did not offer.

The board exposes 26 multi-purpose GPIO pins, three of which can serve as ADC inputs, alongside 2 UARTs, 2 SPI controllers, 2 I2C controllers, 24 PWM channels, a USB 1.1 controller and 12 Programmable I/O state machines. Input power runs from 1.8 to 5.5V DC, and the board is rated for -20C to 85C operation. Raspberry Pi also designed it to be backward compatible with accessories built for earlier Pico boards.

Who it suits

Developers building wireless sensor nodes, connected microcontroller projects or products that need firmware-level security will benefit most from the RP2350's extra memory, wireless radio and TrustZone support, while keeping the same Pico form factor and accessory ecosystem.
