Hmm, to je dobry. Konecne neco s 5GHz :-)
Jedina existujici alternativa o ktere vim je cip RTL8720DN - modul BW16 viz treba https://www.hackster.io/zhu-qi2/getting-started-with-rtl8720dn-bw16-development-board-52eb68
Na aliexpresu cca $3, je na to arduino a firmware je opensource https://github.com/ambiot nebo arduino https://github.com/mikey60/BW16-RTL8720DN-Module-Arduino https://www.amebaiot.com/en/amebad-bw16-arduino-getting-started/ v zakladu je AT command based firmware (i k tomu jsou zdrojaky)
Ale je to docela punkove, ten cip ma dva dost ruzne ARM procesory a firmware obsahuje kod pro oba, na kazdem bezi neco.
Kazdopadne ESP bude mit lepsi komunitu.
