1 Introduction
- All-in-One Android Touch Screen is designed and developed by FriendlyElec. It is a comprehensive solution with a 9" HD LCD and capacitive touch panel. It is based on FriendlyElec's Smart6818 CPU board which uses Samsung's octa-core Cortex-A53 S5P6818. Its frequency can scale up to 1.4Ghz. It has 1GB DDR3 RAM and 8GB eMMC flash.It has a power management unit which implements software power on/off and hardware wake-up functions.It integrates Wi-Fi, bluetooth, Gbps Ethernet and audio. It supports EC20 4G modules.Its display resolution is 1280 x 800. It has a capacitive touch panel. Its back-light is controllable via i2c. In addition it has popular interfaces such as I2C, SPI, RS232-UART, USB etc.These features make it a good platform for fast prototyping and industrial applications.
2 Hardware Spec
