Shield pin configuration
3 High-Level Functional Description
The Intel® Edison kit for Arduino*expansion board is designed to be hardware and software pin-compatible with
Arduino shields designed for the Uno R3. Digital pins 0 to 13 (and the adjacent AREF and GND pins), analog inputs
0 to 5, the power header, ICSP header, and the UART port pins (0 and 1) are all in the same locations as on the
Arduino Uno R3. This is also known as the Arduino 1.0 pinout. Additionally, the Intel® Edison kit for Arduino* board
includes a micro SD card connector, a micro USB device port connected to UART2, and a combination micro USB
device connector and dedicated standard size USB 2.0 host Type-A connector (selectable via a mechanical
microswitch).
