The Raspberry Pi Foundation announced the new Raspberry Pi Pico 2 today, a 21mm x 51mm hobbyist chip built on the in-house RP2350, representing the second generation of this chip type. Compared to the first Raspberry Pi Pico — which came out in 2021 and was built on RP2040 — this one has an increased clock rate (from 133MHz to 150MHz) with more powerful Arm cores, double the flash memory (from 2MB to 4MB), new security features, and upgraded interfaces.
