DC_Z9D3

1. The Dingchang DC_Z9D3 board is ultra-thin, with a thickness of only 7mm. The development board is equipped with the high-performance Amlogic S905D3 quad-core 1.9GHz chip.
2. Targeted at the development field of smart hardware terminals with requirements for thickness. For example, it is suitable for the development of embedded hardware such as access control gates, conference sign-in nameplates, smart buildings, and smart home touch-screen gateways.
3. Applications: When paired with a face recognition algorithm, it can perfectly support the development of industry applications in the access control or face-scanning passage sectors, such as access control for gates and conference sign-in and attendance systems.
4. It can be externally connected to a POE network power supply module or a adapter board.
5. System: It supports Android 9.0.
6. Comprehensive documentation: It provides the download of practical materials such as development documents, firmware, screen parameters etc.
