Overview
The chipKIT Basic I/O Shield is an input/output expansion shield designed for use with chipKIT microcontroller
boards such as the Uno32™, uC32™, and the Max32™. These boards are based on the popular Arduino® IDE open-
source hardware prototyping platform.
The Basic I/O Shield provides a range of input/output devices for both beginners and advanced users. It provides
simple digital input devices such as switches and buttons, and digital output devices such as discrete LEDs and
high-current open FET drivers. It also provides more advanced devices such as an I
2
C EEPROM, an I
2
C temperature
sensor, an organic LED graphic display, and a potentiometer for use as an analog input device.
The Basic I/O Shield has the same form factor as the Uno32 board, but is also useable with the Max32 board.
