1 Introduction

Overview
Front
Back
  • The Smart4418/6818SDK V2 1812 carrier board populates popular interface pins from the the Smart4418/6818 CPU board. These interface pins include HDMI, USB Host, MicroSD card slot, RS-233 port, RS-485 port, RJ-45 Ethernet port, 3.5mm audio input and output, 4G module interface, MicroSIM card slot etc. It has some onboard hardware resources such as buzzer, buttons, RTC battery holder, microphone etc. All the popular interfaces and ports are on the same side. This layout makes it easy for customers to make a customized case for it. This carrier board can work with FriendlyElec's various LCDs such as HD702, HD702V, S430 LCD etc.
  • In order for users to test and develop prototypes this Smart4418/6818SDK carrier board also populates DVP camera interface, SPI, GPIO, I2C, UART and has onboard AP6212 WiFi module, PCB antenna, IPX interface, RTC battery holder. Users can easily connect various devices to this board for testing. This meets the requirements for fast prototyping in various industrial applications.
  • The Smart4418/6818SDK V2 1812 carrier board has both RGB LCD interface and LVDS LCD interface. It can work with FriendlyElec's HD702 LCD, HD702V LCD,S430 LCD. Its RGB LCD pin-header interface and LVDS LCD pin-header interface can be used to test other LCDs as well.
