The "Beaglebone Enhanced" by Sancloud is based on the Beaglebone Black, but with the following differences: * Gigabit capable PHY * Extra USB hub, optional i2c control * lps3331ap barometer connected over i2c * MPU6050 6 axis MEMS accelerometer/gyro connected over i2c * 1GiB DDR3 RAM * RTL8723 Wifi/Bluetooth connected over USB Signed-off-by: Koen Kooi <koen@dominion.thruhere.net> Reviewed-by: Tom Rini <trini@konsulko.com>
