Quick Start Guide 

Installation Procedure

 

1.  Assemble and connect the reference design hardware. 

a. Remove the MAX32630FTHR and MAXREFDES220# sensor board from 
the package. 
b. Connect the MAX32630FTHR and Smart Sensor Boards together. 
c. Connect a mini-USB cable between the PC and the MAX32630FTHR. 

2.  Verify the operation of the MAX32630FTHR host 

a. Immediately after connecting the USB cable, observe the LED on the 
MAX32630FTHR. 
b. If the LED briefly turns yellow, and then blinks green, the MAX32630FTHR 
is programmed correctly and ready for use.
