1 Introduction

Overview

Front

The Smart4418 SDK carrier board V1606 has various interfaces and ports like HDMI port, USB host, SD card slot, SB9 serial port, RJ-45 Ethernet port, 3.5mm audio jack, SATA interface, MiniPCIe, MicroSIM etc with support for 3G/4G Bluetooth & WiFi.In addition it has hardware resources like buzzer, user keys, RTC battery, microphone and etc for users to evaluate its performance and features. FriendlyARM designed it for sake of industrial applications by putting all commonly used interfaces and ports on one side with mounting holes for easy deployment.
To make this carrier board applicable in various applications compared to our existing carrier boards we add more interfaces and ports such as DVP camera interface, SPI, GPIO, I2C, AP6212 WiFi & Bluetooth module, porcelain antenna, RTC seat and etc.
