[noqman]

Hi, can you please help to add this board?
The product is still under development and will be launched soon.

Let me know if there are any issues with it.
Thank you!

Hi, the build is overflowing on one or more languages.

You are freezing a lot of libraries. You could drop some of these:

• adafruit_bus_device is already included as a C implementation. The frozen version will not be used.
• adafruit_sdcard is not needed if sdcardio is enabled.
• simpleio is not really needed. If you want a range() operation, see adafruit_simplemath.
• You are including non-displayio display support with adafruit_framebuf and adafruit_ssd1306. Is it your intention to have both kinds of display support?

Look at the pico 2W build and see if there are any native (built-in) modules you might want to turn off to make room.
