3. 256-Kb I2C Serial EEPROM to store the board ID information
4. 32Mb SPI Flash provided on the EVM for optional booting
5. On Board Audio Codec AIC31066 “Ultra low power microcontroller MSP430 used for power monitoring using the current shunt & power monitor devices INA220
6. Expansion connectors supporting plug-in application boards
7. Two USB-OTG ports with integrated 2.0 PHY
8. Supports analog video output such as, Composite video and S-video
9. 1080p HDMI Video Output with ESD Protection
10. On board Audio Input (Line in and Mic) and Audio Output (Line Out and Headphone)
11. 4-bit SD/MMC interface
12. Two Gigabit Ethernet port with onboard Ethernet PHY’s using RGMII ports
13. Dedicated UART port for Debug and MSP430
14. IR Receiver interface
15. JTAG for DM814x and MSP430
16. PCIeX1 lane support on PCIe-x4 connector
17. SATA 3Gbps direct Interface to HDD with onboard HDD power connector
18. DC supply 12V +/- 5%, 5A Max through Power adapter
19. On-Board Clocks for DM814x and for SATA/PCIe
20. Reset and power on/off switches for controlling the DM814x EVM
21. Boot switches for various boot configuration selection
22. Expansion IO Boards
    1. 512 MBit NOR Flash memory
    2. 3 axis smart digital output accelerometer
    3. 256-Kb I2C CMOS Serial EEPROM to store the board ID information
    4. WLAN Daughter card provides IEEE802.11 b/g/n wireless LAN, Bluetooth v3, including Bluetooth low energy (BLE) connectivity
    5. SPDIF interface through TOSLINK & RCA jack Analog SD IN (S-Video & composite video) digitized using TVP5147M1 decoder
    6. Analog HD IN (RGB & VGA) using triple high-performance analog-to-digital (A/D) converter TVP7002
    7. Digital HD Video capture using DVI Receiver (SiI1161)
    8. LCD connector for interfacing LCD adapter board Serial camera interface through CSI
    9. 12- Bit parallel camera interface
    10. UART
