I can't imagine someone using an RP2040 in a real product, but the RP2350 fixes enough of my complaints that I'd be really excited to give it a shot. There's a lot going for the 2040, don't get me wrong. TBMAN is a really cool concept. It overclocks like crazy. PIO is truly innovative, and it's super valuable for boatloads of companies looking to replace their 8051s/whatever with a daughterboard-adapted ARM core. But…

I wonder if it is more about simply shaving a few cents off. Full USB-C protocol implementation may be much more difficult.
USB-C doesn't require anything special USB wise as it's decoupled from the versioned standard. It just has more pins and works with all modern cables. Ideally the cables won't wear out like Mini and Micro and get loosey goosey in the ports.
And still no USB C on the official devboard.
> And still no USB C on the official devboard. Do you live in a universe where micro-USB cables are not available, or something? There's gonna be something or other that needs micro-USB for the next decade, so just buy a few and move on. They're not expensive. [later edit: I bet it has to do with backwards compatibility. They don't want people to need to rework case designs to use something that is meant as a drop-in…
I live in a universe where type C has been the standard interface for devices for years, offering significant advantages with no downsides other than a slightly higher cost connector, and it's reasonable to be frustrated at vendors releasing new devices using the old connector.
It's certainly not as bad as some vendors of networking equipment who still to this day release new designs with Mini-B connectors that are actually officially deprecated, but it's not good nor worthy of defending in any way.

Your logic is likely accurate here, but that just moves the stupid choice back a generation. It was equally dumb and annoying to have Micro-B instead of C on a newly designed and released device in 2021 as it is in 2024.
The type C connector was standardized in 2014 and became standard on phones and widely utilized on laptops starting in 2016.
IMO the only good reason to have a mini-B or micro-B connector on a device is for physical compatibility with a legacy design that existed prior to 2016. Compatibility with a previous bad decision is not a good reason, fix your mistakes.
Type A on hosts will still be a thing for a long time, and full-size type B still makes sense for large devices that are not often plugged/unplugged where the size is actually a benefit, but the mini-B connector is deprecated and the micro-B connector should be.
Some specs here: https://www.digikey.ca/en/product-highlight/r/raspberry-pi/r... Based on the RP2350, designed by Raspberry Pi in the United Kingdom Dual Arm M33s at 150 MHz with FPU 520 KiB of SRAM Robust security features (signed boot, OTP, SHA-256, TRNG, glitch detectors and Arm TrustZone for Cortex®-M) Optional, dual RISC-V Hazard3 CPUs at 150 MHz Low-power operation PIO v2 with 3 × programmable I/O co-processors…
Edit: See comment below; The RP2350 can be powered by a 5V supply.
But the µC itself runs on 3.3V and is not totally 5V-capable. You'd need level converters to interface with 5V.

Perhaps they could be more ready-made, but there are loads of official PIO examples that are easy to get started with.

RP2350 looks very much like it could potentially run Quake. Heck, some of the changes almost feel like they're designed for this purpose.
FPU, two cores at 150 MHz, overclockable beyond 300 MHz and it supports up to 16 MB of PSRAM with hardware R/W paging support.
Gross, the dev board uses micro-USB. It's 2024! Otherwise amazing work. Exactly what's needed to compete with the existing giants.
Perhaps the unfortunate choice of micro USB is to discourage real consumer products from being built with the dev board.
There are one-time programmable registers for Vendor, Product, Device and Language IDs that the bootloader would use instead of the default. It would be interesting to see if those are fused on the Pico 2.

5V GPIO is a huge deal for me - this immediately opens up a huge range of integrations without having to worry about line level conversion. I can’t wait to use this!
Does tolerant mean ok to do? Or it just won’t fry your chip but you should actually run at 3.3?
