1.  Introduction 

The QN908x DK board is designed for the QN908x HVQFN and WLCSP package IC 
evaluation and development. It is easy to evaluate QN908x

’s functions and performance. 

There are also some useful peripherals like the GPIOs, PMod, and Arduino interface. 
The J-Link and J-Trace functions are supported for the QN908x debugging. The ISP 
download function is also supported and very easy to use. 

1.1  Purpose 

This document introduces all functions of the QN908x DK V1.2 board and describes all 
its parts in detail.  

1.2  Kit contents 

QN908x DK includes the following: 

  QN908x DK board 

  QN9080 USB dongle 

  USB cable
