Ai-Thinker BW20-12F WIFI+BLE Module
BW20-12F is a dual-band Wi-Fi + BLE SoC module based on RTL8711 series chips, which supports dual-frequency (2.4 GHz cr5 GHz)802.11a/b/g/n WLAN protocol and Bluetooth 5.0 protocol.
The BW 20-12F integrates dual-core MCU, an ARM V8.1 (Cortex-M4F compatible) high-performance MCU with a maximum frequency of 330 MHz; an ARM V8M (Cortex-M0 compatible) low-power MCU.
The BW20-12F module has rich peripheral interfaces, including UART/ GPIO / ADC/PWM/
IIC / SPI / SDIO / IR / SWD / USB etc. It can be widely used in the Internet of Things (IoT),
mobile devices, wearable electronic devices, smart homes, and other fields.
