BeagleBone Blue

Description
The BeagleBone Blue is the affordable and complete robotics controller built around the popular BeagleBone open hardware computer. Linux-enabled， the Blue is community-supported and fully open-source.
High-performance， flexible networking capabilities are coupled with a real-time capable Linux system and a compelling set of peripherals for building mobile robots quickly and affordably. Utilizing the pre-configured Wi-Fi access point， starting your code development is as simple as connecting a battery and opening your web browser.
BeagleBone Blue features an Octavo Systems OSD3358 System-in-Package microprocessor together with WiFi/Bluetooth， IMU/Barometer， power regulation， and state-of-charge LEDs for a 2-cell LiPo， H-Bridges， and discrete connectors for 4 DC motors+encoders， 8 servos， and all of the commonly-needed buses for additional peripherals in embedded applications.
