2.  Hardware description 

The QN908x DK board provides easy access to peripherals, such as the buttons and 
LED. The board also provides useful interfaces, such as the USB port for UART 
communication and CMSIS-DAP debugger, and the standard Arduino & Pmod 
connector. The USB dongle is a Bluetooth device powered by QN9080. It acts as a 
master/slave when communicating with the QN908x devices. 

2.1  Hardware overview 

The QN908x DK V1.2 board is shown in 

Fig 1
