The Basic I/O Shield is designed to provide a range of input/output devices suitable for beginners learning about microcontrollers and various types of I/O devices, or for use by more advanced user to provide inputs or outputs for their own projects. The Basic I/O Shield 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 provides more advanced devices such as an 2 2 I C EEPROM, an I C temperature sensor, and organic LED graphic display. A potentiometer is also provided for use as an analog input device. The Basic I/O Shield is designed to the same form factor as the Uno32 board, but is also useable with the Max32 board. Features: 128x32 pixel OLED graphic display 2 I C temperature sensor 2 256Kbit I C EEPROM 2 I C daisy chain connector 4 push buttons 4 slide switches 8 discrete LEDs 4 open drain FET drivers Analog potentiometer Doc: 502-216 page 1 of 15 Copyright Digilent, Inc.
