SDK • Re: Pico SDK binary size?

The WiFi chip needs firmware to be loaded to operate. That blob is over 200kB by itself.

I don't have a sense for how much code lwip is adding.

MicroPython for the Pico comes in at about 300 KB, for the Pico W it comes in around 700 KB. So that's an added 400 KB including the binary blob, the CYW43 driver, LwIP, plus the glue which ties it all together. That will include in-built MicroPython modules which wouldn't be needed with Pico SDK code. As a guesstimate I might say it would be adding about 300 KB in that case.

If so that could position your code around the 50 KB mark.

Though it's understandable to be intrigued by the amount of code, and what's producing it, I wouldn't particularly worry about it unless you have significantly more to add and are getting close to the limit.
