Where the original Pico ran dual Cortex-M0+ cores at 133MHz, the Pico 2 upgrades to dual ARM Cortex-M33 cores at 150MHz — and uniquely allows the developer to boot into dual RISC-V Hazard3 mode instead, making it the first commercially available board to offer a switchable dual-ISA architecture. This flexibility is particularly interesting for bare-metal and RTOS developers exploring RISC-V. The hardware delivers exactly double the memory of the original Pico: 520KB of on-chip SRAM (up from 264KB) and 4MB of QSPI flash (up from 2MB). The same 26 multi-purpose GPIO pins are broken out, four of which are usable as 12-bit ADC inputs. Two UARTs, two SPI controllers, two I2C buses, 24 PWM channels, and 12 PIO state machines (up from 8 on RP2040) are available for peripheral interfacing. Power input is 1.8–5.5V, and the USB 1.1 controller supports both host and device mode. Unlike the Pico 2W, the Pico 2 has no wireless radio, keeping the BOM cost low for applications that don't require WiFi or Bluetooth. New security features in the RP2350 include hardware AES, SHA-256 accelerator, an on-chip True Random Number Generator, and support for a secure boot chain — features absent from RP2040. Note: the A2 silicon revision carries the E9 erratum affecting certain GPIO pull-down configurations with PIO state machines. The Pico 2 is fully supported by the official Raspberry Pi Pico SDK, MicroPython, and CircuitPython. It is pin-compatible with the original Pico, allowing most existing Pico projects to run without hardware changes. The "with header" variant ships with pre-soldered 2.54mm pin headers, making it breadboard-ready out of the box. ## Where to Buy - [Adafruit (without header)](https://openhardware.directory/r?to=https%3A%2F%2Fwww.adafruit.com%2Fproduct%2F5526&ref=openhardware.directory&product=raspberry-pi-pico-2&source=md-export) — $7.00 - [Adafruit (with header)](https://openhardware.directory/r?to=https%3A%2F%2Fwww.adafruit.com%2Fproduct%2F6328&ref=openhardware.directory&product=raspberry-pi-pico-2&source=md-export) — $7.50 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fwww.raspberrypi.com%2Fproducts%2Fraspberry-pi-pico-2%2F&ref=openhardware.directory&product=raspberry-pi-pico-2&source=md-export) - [github](https://openhardware.directory/r?to=https%3A%2F%2Fgithub.com%2Fraspberrypi%2Fpico-sdk&ref=openhardware.directory&product=raspberry-pi-pico-2&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-2&source=md-export) - [schematics](https://openhardware.directory/r?to=https%3A%2F%2Fdatasheets.raspberrypi.com%2Fpico%2FRPi-Pico-R3-PUBLIC-20200119.pdf&ref=openhardware.directory&product=raspberry-pi-pico-2&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-2&source=md-export) ## Tags `raspberry-pi`, `pico`, `rp2350`, `microcontroller`, `risc-v`, `cortex-m33`, `circuitpython`, `micropython` ## Images ![Raspberry Pi Pico 2](https://nbg1.your-objectstorage.com/openhardware-directory/entities/raspberry-pi-pico-2/1cf77b617eea.jpg) ![Raspberry Pi Pico 2](https://nbg1.your-objectstorage.com/openhardware-directory/entities/raspberry-pi-pico-2/19c86f50a8aa.jpg) --- [View full device page](https://openhardware.directory/devices/raspberry-pi-pico-2)
