RP2040 is really great experience. You can get a debug probe (either buy or make yourself with another RP2040)

I cant tell you how awesome it is with minimal setup to get

- Full print logging

- Option to attach a debugger

- cargo r will just flash your code and reset the RP2040

probe-rs is amazing. In ARM land it works with pretty much any CMSIS compliant gear, and yeah you get debugging and logging on pretty much anything as a result.

I wish they had smaller modules with wifi (pico w is too large for many of my usecases). That's the only reason I keep using ESP-C*. It's getting better but the esp-rs tooling has a lot of very rough edges.

Same. Non-Espressif manufacturers have been sleeping on Wi-Fi capability. Nordic now has a chip, but I haven't tried it. I have been using an Esp running Esp-Hosted, connected to the main MCU over SPI.

It is a little bit complicated to start and understand how the series ESP-S* works, but as soon you do, everything gets better. It does have Wi-Fi and Bluetooth capabilities and also can be very small. A good example are the Adafruit Qt Py series. I am currently working with the Adafruit Qt Py (ESP-S2) and I am in love to that board. This one, doesn’t have Bluetooth, but the S3 does.

Because of the Xtensa, you need to use a special fork of Rust maintained by Espressif, but worth a try.

You've got boards like the Seeed Studio Xiao with an RP2040, that board is absolutely tiny!

The 2040/2350 ones don't have wireless radio.

Oh.. my brain completely skipped "with wifi" in your comment, my bad.

You had me excited for a second :)
