Raspberry Pi Pico 2 is faster and backward-compatible, still only $5

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.

This new microcontroller board promises a significant increase in performance and more versatility for whatever ideas and projects you can dream up. At the same time, the hardware should be backward-compatible with older Pico components.

The Raspberry Pi Pico 2 — which is programmable using C, C++, and Python — is available in various housing options and is intended for DIY projects that are too big or too powerful for a Raspberry Pi to handle.

But the most shocking thing about this release? The new Raspberry Pi Pico 2 has an astonishingly low price of just $5.
