5.4.1 User and Power LEDs

Three LEDs are provided on the FPB-RA4E1 board. The fourth LED (POWER) can also be fitted if desired.
A suitable part is Würth Elektronik 732-4971-1-ND.
Behaviour of the LEDs on the FPB-RA4E1 board is described in the following table.

Table 8. FPB-RA4E1 Board LED Functions

Designator Colour Function
LED1 Green
LED2 Green
POWER Green
DEBUG/POWER Yellow
The User LEDs may be isolated from the main MCU so that the associated ports can be used for other
purposes. To disconnect LED1 from P408, trace cut jumper E10 must be open. To disconnect LED2 from
P407, trace cut jumper E9 must be open.
