Allwinner R7

Cost-effective robot cleaner solution

Overview

Allwinner R7 integrates a single-core ARM CortexTM-A7 CPU that operates at speed up to 1.2GHz. A 64MB DDR2 is embedded in Allwinner R7. Allwinner R7 support s SLAM and VSLAM, which meets requirements in robot sweeper applications. It also integrates H.264 720p@60fps encoder, and rich interfaces such as MIPI CSI, DVP camera interface, UART, PWM, LRADC, C ODEC, and EMAC. Besides, Allwinner R7 can support TINA OS. Allwinner R7 is qualified to industrial standard in white electricity industry.
