Product Overview

The 20 Arduino*-compatible shield I/O pins on the Intel® Edison kit for Arduino* are numbered IO0-IO19 (Figure 1).
All pins support basic GPIO functionality. Some of the pins also support PWM, ADC, SPI or I
of different pin functions on the Intel® Edison kit for Arduino* is achieved through use of SoC pin control interfaces
and GPIO output signals dedicated for multiplexing control. The following sections detail the mapping of each of
the GPIO pins available on the Intel® Edison compute module to their respective functions, which can be broadly
categorized as follows (see Figure 1):
•
External GPIO. Used for digital input/output signaling via the external shield pins.
• Pin multiplexing control. Used for selecting different functions available on a given shield pin.
•
Pin buffer (level-shifter) direction control. Used to configure the buffer on a given shield pin for input or
output.
•
Pin pullup resistor control. Used to enable/disable a pullup resistor on a given shield pin.
To use any of the supported functions on a shield pin, it is first necessary to configure the multiplexing, buffer
direction, and pullup resistor controls applicable to that pin.
