Example Of Applying ITEAD A20 CORE With RDM8800

By using ITEAD A10/20 CORE with different functional baseboards, you can easily achieve a variety of specific application development. Here, we’d like to show you an example of applying ITEAD A20 CORE with NFC intelligent system baseboard.

Framework of the entire system is shown as below:

Development of the baseboard is quite simple, as which does not need complex high-speed digital circuit design, and it only requires a simple two-layer board . CORE is connected to a 7-inch screen via LVDS interface, and then connected RDM8800 (an NFC card reader module) through UART interface. In order to facilitate the development , the board also extends 4 USB ports through USB HUB chip.

RDM8800 is also an open-source NFC card reader module which can be used for secondary development according to the needs. After the information such as card number is read through the module, it will be transmitted to A20 main control via UART to process and to perform relevant actions.

As a DEMO, we only display the NFC card number that is read in a simple UI window, which is not quite significant. However, with more deepgoing development, we can imagine more applications for it:

If operating system running on CORE is installed with database and specific application, it can work as intelligent attendance system to record the commute time by card punching for statistical data analysis – a WIFI dongle can be installed via USB port, thus such data can be synchronized to the Internet through WIFI or directly downloaded to U disk via USB port.

It is our goal to achieve a variety of quick prototyping development by using ITEAD A10/20 CORE with simple customized baseboard and application. As this is only a function presentation and time is limited, it looks quite rough. We do welcome fellows of ideas to offer more proposals, or you can even join us to create a new open-source NFC intelligence system project together or to provide a more stable and more mature open-source NFC intelligent center solution.
