The OpenRex?s dimensions are 95mm long and 70 mm wide. Compared with the Raspberry Pi 2?s dimensions (85.60 mm ? 56.5 mm), OpenRex is larger and harder to replace any of the Raspberry Pi or Arduino board in small spaces.
On both sides of the board, are placed two GPIO headers which should be very familiar to any Raspberry Pi or Arduino users. If you would like to use a Raspberry Pi on steroids or a more featured Arduino board, OpenRex is the alternative of both of them.
The board features a series of built-in sensors including compass and accelerometer, gyroscope, humidity sensor, and temperature sensor. These sensors are a helping hand if you choose to build drones, robots or home automation applications.
The development board is 5V DC compatible and support two types of input power: through Power Jack or USB micro
