External J-Link Programming and Debug Interface 
 
For the embedded MCU in the SGW2828 LoRa Module, firmware programming and debugging is done 
via the external J-Link interface at header 

J11

. The interface is implemented by using 1 x 4 2.54mm pitch 

4-pin header. 
 
To ensure the proper use of external J-Link connection, the external device must be connected to the 
following pins: 

•

 

SWD_IO, SWD_CLK 

•

 

Connect power pin from SWG2828 LoRa Module
