Gravity: Expansion Shield for Intel® Joule™

INTRODUCTION

DFRobot’s Expansion Shield for Intel® Joule™ is a powerful add-on component to the Intel® Joule™ compute module with its carrier Expansion Board for Intel® Joule™. Other than what is originally supported by Intel® Joule™ and the expansion board, the expansion shield adds following features especially for robotics, smart gadget, and IoT device development uses.

• Analog input support
• 3.3V / 5V switchable power voltage
• Standard extended connectors (DFRobot Gravity Series sensors and modules compatible)
• The expansion shield is sized just as big as the expansion board and can be easily mounted on to the expansion board through breakout pins. Its well-designed shape and layout allows you to get all access to the connectors, LED indicators and buttons on the Intel® Joule™ compute module and the expansion board.
