chipKIT™ Basic I/O Shield™ Reference Manual

Note: On the Uno32 and uC32 boards, you need to set jumpers JP6 & JP7 to the correct position to

access the I

C signals on that board. On the Max32 board, you need to use jumper wires to bring the

C signals onto the board, because the connector that provides the I

doesn't contact the Basic I/O Shield.

5. Discrete LEDs

The eight LEDs provide discrete digital outputs. These can be accessed individually using the

digitalWrite function. The LEDs are connected to the low eight bits of microcontroller PORTE and all

eight can be written at the same time by writing to PORTE.

6. IC2: Temperature Sensor

This is a Microchip TCN75A digital temperature sensor. It is accessed via the I

7. JP2 & JP3: I

C Pull-up Resistor Enable Jumpers

These jumpers are used to enable or disable the I

shorting blocks enables the resistors. Removing the shorting blocks disables the resistors.

8. J11: I

C Daisy Chain Connector

This is a 2x4 pin header connector that provides access to the I

power from the 3.3V power bus and ground. The connector can be used to extend the I

another board and to power an external I

peripheral modules that can be connected to this shield.

9. Potentiometer

This is a 10K-ohm potentiometer connected across VCC3V3 and ground. It provides an analog input

voltage to analog input A0.

10. J1 & J2: Digital Signal Connectors

These connectors bring digital signals from the chipKIT microcontroller board to the Basic I/O shield.

11. Organic LED Graphic Display

This is a 128x32 pixel monochrome OLED graphic display panel is accessed using the SPI interface.

12. J9 & J10: Digital I/O Signal Connectors

These are screw terminal connectors that provide access to digital I/O signals 3, 5, 6, and 9. These are

four of the PWM signals from the chipKIT microcontroller board.

13. J6: Open Drain FET Power Connector

This provides access to the power connections for the open drain FETs.

14. J7 & J8: Open Drain FET Output

These provide access to the outputs of the open drain FETs.
