After some soldering and burn the Arduino bootloader,Linkit connect with Arduino is completed
for the software, I modify the sample code from Linkit connect cmd set to build a simple web server.(I'll put the details in instruction)
But this version has a little problem, I made a mistake of breaking net between 3.3V and VCC.
It has to be connected otherwise Atmega32U4 and Linkit connect module won't power up,
thankfully, the VCC output and the 3.3V output from LDO is pretty close. So I just solder a bridge to connect them.I'll update the version later on both github and OSHpark
