This is a good blog post, with die photos of the new RP2350 chip and a brief description of what they show. There is a link to a 12 minute youtube video that is also very good, that discusses the die shots in more detail and also goes over the rest of the Pico 2 circuit board, including die shots of the QSPI flash chip and the voltage regulator chip.
Great stuff. Waiting on the ‘W’ edition.
If it’s like the Pico W, that will be like the regular version with a 3rd party wireless chip added, maybe even the same chip already used in the Pico W.
I’d like to see a Linux board in the Pico form factor, using Risc-V with appropriate MMU extensions, less powerful than a Pi Zero and hopefully still at the $5 price point. SIngle or double Risc-V core and 64MB of ram plus an SD slot makes a pretty nice embedded Linux board.
Good news! It already exists: https://milkv.io/duo
