Device

Function

 

 

 

 

5V OK

Green

D29

Indicates that the 5V power supply is on

 

 

 

 

3V3 OK

Green

D34

Indicates that the 3V3 power supply is on

 

 

 

 

Standby

Red

D39

Indicates that the PB926EJ-S is in standby mode and the

 

 

 

power is off. This LED only functions when power is

 

 

 

supplied to the board via connector J35

 

 

 

 

Config

Amber

D44

Indicates that the PB926EJ-S is in configuration mode.

 

 

 

Configuration mode is entered by fitting the CONFIG

 

 

 

link J32 on the board and powering-up

 

 

 

The CONFIG link is a switch on some board versions.
