SparkFun RedBoard
RFU
- This pin is reserved for future use.
11
Power In
(Barrel Jack) - Can be used with either a 9V or 12V wall-wart or battery.
1
Power In
(USB Port) - Provides power and communicates with your board when plugged into your computer via USB.
2
LED
(RX: Receiving) - This shows when the FTDI chip is receiving data bits from the microcontroller. This happens when the microcontroller is
sending data bits back to the computer.
3
LED
(TX: Transmitting) - This shows when the FTDI chip is transmitting data bits to the microcontroller. This happens when the
microcontroller is receiving this data from the computer.
4
LED
(Pin 13: Troubleshooting) - This LED is incorporated into your sketch to show if your program is running properly.
5
Pins
(ARef, Ground, Digital, Rx, Tx) - These various pins can be used for inputs, outputs, power, and ground. // See Diagram Below
6
LED
(Indicates RedBoard is ON) - This is a simple power indicator LED.
7
Reset Button
- This is a way to manually reset your RedBoard, which makes your code restart.
8
Pins
(Analog In, Power In, Ground, Power Out, Reset) - These various pins can be used for inputs, outputs, power, and ground. // See Diagram
10
ICSP Pins
(Uploading Code without Bootloader) - This is for "In-Circuit Serial Programming," used if you want to bypass the bootloader.

The header pins are one of the most important parts for putting our
example circuits together. Take a moment and locate the input/output
ports of your RedBoard.
