It's exciting news for RISC-V fans: Raspberry Pi is adding support for the open ISA with the release of the Pico 2 and the company's new RP2350 microcontroller.

The Pico 2 board retails for $5 and, according to the Pi team, maintains backward hardware and software compatibility with previous versions. Although the on-chip memory has been increased to 520KB – there is also 4MB of built-in QSPI flash – the two RISC-V Hazard3 CPU cores included in the microcontroller may well interest enthusiasts and implementers alike.
The Hazard3 cores are optional: On boot, users can select a pair of bundled Arm Cortex-M33 cores to run, or the pair of Hazard3 cores. Both options run at 150 MHz. The more daring can try driving an RV and an arm core together instead of two RVs or two arms.
