It can boot using either two Arm Cortex-M33 cores or two open-hardware Hazard3 RISC-V cores—not all four cores at once. A launch-day roundup named products from several maker vendors and the DEF CON 32 badge; that list is a snapshot from August 2024, not a current inventory.
What is the RP2350?
The RP2350 is the microcontroller chip; Raspberry Pi Pico 2 is a development board built around it. Raspberry Pi announced the chip and Pico 2 on August 8, 2024, pricing the board at $5 at launch. That is a historical launch price, not a statement of current retail pricing. Raspberry Pi’s launch announcement has the original details.
The chip’s notable feature is selectable processor architecture. Firmware can use either a pair of 150 MHz Arm Cortex-M33 cores or a pair of Hazard3 RISC-V cores. Raspberry Pi says the boot ROM can identify the architecture expected by the second-stage binary and restart in the appropriate mode. The two architectures are alternatives, not four cores available simultaneously.
RP2350 and Pico 2 specifications
Raspberry Pi’s launch materials and current Pico 2 product page describe the following features. Chip package options and the board’s onboard flash are different things:

The Cortex-M33 implementation includes floating-point and DSP support. The details above are vendor-published specifications; Raspberry Pi’s RP2350 documentation index lists the datasheet, updated October 2, 2026.
Which board is the easiest way to start?
For a hands-on starting point, Raspberry Pi Pico 2 is the direct development board choice. Raspberry Pi says it is hardware- and software-compatible with earlier Pico-series boards and supports C/C++ and MicroPython. The Pico 2 product page also states that the Pico 2 series will remain in production until at least January 2040.
