Realtek RTL8720DN is a WiFi and Bluetooth module that has dual bands for WiFi communication. It is worth saying that this little module can support WiFi 5G and Bluetooth Low Energy 5.0 as well. This WiFi and Bluetooth module is a highly integrated WiFi and Bluetooth module with the main chip RTL8720DN, it can be regarded as an SoC for the WiFi and Bluetooth application with typical SBCs.
Except for the main chip, the Realtek8720DN module consists of a high-performance MCU named KM4, a low power MCU named KM0, WLAN (802.11 a/b/g/n) MAC, a 1T1R capable WLAN baseband, RF, Bluetooth, and peripherals. An inner antenna and many interfaces are available in this little WiFi and Bluetooth module.
Compare with ESP series, this WiFi and Bluetooth module has more functions like 5G WiFi and Bluetooth 5.0. As a matter of fact, this little module can be widely used for more applications than the ESP series.
