1 Introduction to Evaluation Board
Chuanglong Technology TLT3-EVM is a 4-core ARM Cortex-A7 high-performance low-power domestic evaluation board designed based on Allwinner T3 processor. The main frequency of each core is up to 1.2GHz. It consists of a core board and an evaluation board.
The evaluation board is rich in interface resources, leading out communication interfaces such as dual network ports, dual CAN, dual USB, and dual RS485, onboard Bluetooth, WIFI, 4G (optional) modules, and simultaneously leading out MIPI LCD, LVDS LCD, and TFT LCD , CVBS OUT, CAMERA, LINE IN, H/P OUT and other audio and video multimedia interfaces, support dual-screen different display, 1080P@45fps H.264 video hardware codec, and support SATA mass storage interface.
The core board adopts 100% domestic components and has been verified by professional PCB layout and high and low temperature tests. It is stable and reliable, and can meet various industrial application environments. Most of the components on the evaluation board adopt domestic solutions, which is convenient for users to quickly conduct product solution evaluation and technology pre-research.
