Connector 

Type 

Description 

J3 

Power 

USB Type-C connector for DC input through a USB-C power 
adaptor or QC/AFC type AC/DC adaptor *  
This connector is also used to download configuration 
data/firmware from the Wireless Configuration Utility through 
HPI dongle over the Type-C CC lines. For more information, see 
section 

4.2

. 

J6 

Power 

SMD connector option for DC input through a variable DC power 
supply *  

J1 

Signal 

Debug serial port. Connect to an HPI dongle (which is provided 
as part of the reference board package) to view system status on 
a PC using a terminal emulator software (Tera Term, Putty, and 
so on). The data is sent at 1-M baud rate. 

J2 

Signal 

SWD connector.  This connector is used to download 
configuration data/firmware from Wireless Configuration Utility 
through an HPI dongle over I2C lines. For more information, see 
section
