Any production ready hardware available?

Hello people,

I was wondering is there any production ready hardware available to use?

Any suggestions appreciated.

What do you mean? There are plenty of boards mounting RP2350, RP2040 or ESP32-S3 for selling from different vendors.

I mean as in the usb key form factor.

I did not find it.
I use Tiny2350 which is not USB key but is really tiny.

Edit: there's Trinkey QT2040 but is RP2040 and the size is wider than normal USB, it might collide with neighbor usb keys.

Thanks for sharing your findings @polhenarejos

So, after searching for sometime, I decided to build my own USB-C key which can accommodate RP2350/RP2354. And of-course decided publish all of the resources.

Here is the initial version of the schematic: https://github.com/abu-matterize/pico-keychain/blob/main/hardware/schematics/picokey-schematic-v1.0.pdf

Suggestions and scrutinizes welcomed.

What GPIO24 will be used for?
Not sure why GPIO23 is connected to voltage regulator.
SC and SD do not seem to be connected to anywhere.
I would prefer a RGBW neopixel rather than a plain green led. Most of the boards equip a neopixel.

An additional button if in case required.

Of-course. Will change it to WS.

Those are SWD/CLK pins for debugging in testing. Would it make any difference leaving as it for production?
