The Pico 2 board retails for $5 and, according to the Pi team, retains backwards hardware and software compatibility with previous versions. While the on-chip memory has been upped to 520KB – there is also 4 MB of on-board QSPI flash – the two RISC-V Hazard3 CPU cores included in the microcontroller may well interest enthusiasts and implementers alike.
