Raspberry Pi Pico 2 RP2350 Microcontroller Development Board - 520 KB SRAM, 4 MB Flash

The Raspberry Pi Pico 2 is the RP2350-powered successor to the original Pico, and it keeps everything that made the first board easy to live with - the 51 × 21 mm DIP footprint, the 40-pin breadboard-friendly layout, drag-and-drop USB flashing - while roughly doubling the compute underneath. Two Arm Cortex-M33 cores or two Hazard3 RISC-V cores (selectable at boot) run at up to 150 MHz , backed by 520 KB of on-chip SRAM and 4 MB of onboard QSPI flash.

That extra headroom is what you feel in practice: larger MicroPython programs, deeper sensor buffers, floating-point and DSP maths that used to be out of reach, and several PIO-driven interfaces running at the same time. Existing Pico projects and add-on boards carry straight over, so you can move a working build onto this RP2350 microcontroller board without redesigning your wiring.

Key Features

•⚡ Dual-core, dual-architecture RP2350A - run two Arm Cortex-M33 cores or two Hazard3 RISC-V cores at up to 150 MHz, with an on-chip PLL for variable core frequency.

•🧠 520 KB SRAM + 4 MB QSPI flash - nearly double the original Pico on both counts, with a 16 KB XIP cache so code runs from flash without stalling.

•🔧 26 multi-function GPIO - 2 × UART, 2 × SPI, 2 × I2C, 16 PWM channels and 3 ADC inputs fed by a 12-bit 500 ksps converter. All IO is fixed at 3.3 V.

•🎛️ 12 PIO state machines - three programmable IO blocks that let you build interfaces the chip has no dedicated peripheral for, such as SD card, VGA or addressable LED strips.

•🔒 Hardware security block - Arm TrustZone for Cortex-M, signed boot, 8 KB of antifuse OTP for key storage, SHA-256 acceleration, a hardware TRNG and fast glitch detectors.

•🔋 Flexible 1.8-5.5 V supply - an on-board buck-boost SMPS runs the board from micro-USB, a single Li-ion cell or 3 ×…
