Raspberry Pi Pico W: your $6 IoT platform
If I understand it correctly, it uses the closed-source library libcyw43 from MicroPyton to communicate with the hardware chip.<p>The library is closed source, I think, because it uses propriety Cypress code.<p>Cypress apparently since released source code and the author had considered releasing an open source version of the library but it never eventuated. See this discussion from 2019:<p><a href="https://github.com/micropython/micropython/pull/4669#discussion_r307131392" rel="nofollow">https://github.com/micropython/micropython/pull/4669#discuss...</a><p>Seems bizarre to me that rpi didn't just create a non-proprietary library.
