Product description: Realtek RTL8720DN Dual-Band communication module - WiFi 2.4GHz/5GHz and Bluetooth 5.0
Realtek RTL8720DNcommunication module, allowing to implement wireless communication to our project. The product allows for WiFi communicationusing2.4GHzand5GHzand Bluetooth LowEnergy 5.0. Apart from the chipitselfresponsible for communication, the product has high qualityKM4 and KM0 microcontrollers. The module has an internal, built-in communication antenna.
Wirelesscommunication moduleRTL8720DN.
Interfaces implemented in the RTL8720DN module
The module has 16 output pins on the back of the board, through specific pins we can use specific interfaces. These are:
- 1x ADC interface
- 2x UART interface with standard transmission speed
- 1x I2C interface
- 1x SPI interface
- 6x PWM interface
Furthermore, all interfaces can be used as GPIO.
