Ai-Thinker BW12-16Mb

BW12 is a highly integrated WIFI SOC module. The main chip RTL8710BX is a low-power chip with a built-in ARM-CM4F MCU, integrating WLAN, MAC, 1T1R-supported WLAN baseband and RF baseband, and provides a set of configurable GPIO pins for control of various peripheral devices. The BW12 features a fully functional built-in WIFI protocol stack, and the embedded memory supports straightforward application development.
