[[File:Smart4418-SDK-A01.jpg|thumb|500px|Front]]
The Smart210/4418 SDK carrier board has rich interfaces and ports. Besides the popular HDMI, USB host, SD card slot, DB9 port, RJ-45 Ethernet port, audio input and output it has onboard EEPROM, buzzer, user keys, GPIO, SDIO which allow users able to fully assess a CPU board. In order for users to conveniently carry it and work with and mount different LCDs we carefully designed the board's layout such that it can work with FriendlyARM's 3.5"LCD, 4.3"LCD, 5"LCD, 7"LCD and 10.1"LCD.
