Debug of the GL865 V3/V3.1 in production 

To test and debug the mounting of the GL865 V3/V3.1, we strongly recommend 

foreseeing test pads on the host PCB, in order to check the connection between the 

GL865 V3/V3.1 itself and the application and to test the performance of the module 

connecting it with an external computer. Depending by the customer application, these 

pads include, but are not limited to the following signals: 

 

•

 

TXD 

•

 

RXD 

•

 

RTS 

•

 

RESET* 

•

 

GND 

•

 

VBATT 

•

 

TX_AUX 

•

 

RX_AUX 

•

 

PWRMON
