hi

CP830 module is said to deliver up to 150Mbps data rate.
it's available on ebay for about $5, incl shipping.
is based on RealTek RTL8711AF

i cannot find this chip or module on this site or hackaday.

details:
CP830 is a highly integrated module with low power 802.11n Wireless LAN(WLAN) network controller.
It combines an ARM-CM3 MCU, WLAN MAC, a 1T1R capable WLAN baseband, and RF function.
It also provides a bunch of configurable GPIOs which are configured as digital peripherals fordifferent applications and control usage.
CP830 integrates internal memories for complete WIFI protocol functions. The embedded memory
configuration alsoprovides simple application developments.

No sh*t. You wonder why

- Mon Aug 14, 2017 7:45 pm #69072 Looks fairly new, might be interesting in the near future when the early adopters have played with it.

My Mandarin/Kantonese/??? is quite rusty, but this website has some details (I think).

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
