JUMPER DESCRIPTION:
LED1_E
This jumper, when closed, enables LED1.
Default state is closed.
G9/F0
This jumper, when is in position G9 – connects UEXT pin 10 (UEXT_#CS) to CON5
pin 3 (D10(#SS)) and when is on position F0 – connects UEXT pin 10 (UEXT_#CS) to
PIC32MX440F256H pin 58 (RF0).
Default state is in position F0.
INPUT/OUTPUT:
Status Led with name LED1 (green) connected via jumper LED1_E to
PIC32MX440F256H pin 4 (RG6) – signal D13(SCK/LED1).
Status Led with name LED2 (yellow) connected to PIC32MX440F256H pin 49
(#U1RTS/OC2/RD1).
Power-on LED (red) with name PWR_LED – this LED shows that the board is
power supplied.
User button with name BUT connected to PIC32MX440F256H pin 46
(OC1/INT0/RD0) and pin 52 (OC5/IC5/PMWR/CN13/RD4) – signal D2(BUT).
Note that you should be careful with D2 signal on the digital connector since it
goes to two microcontroller pins.
User button with name RST connected to PIC32MX440F256H pin 7 (#MCLR).
