Chapter 2. Hardware
This chapter describes the hardware features used in the MEB II and the 4.3" WQVGA
PCAP Touch Display Board.
2.1 HARDWARE FEATURES
2.1.1 Power Supply
Power can be supplied to the MEB II in two ways: 1) through the DC connector (J3)
located on the MEB II (Figure 2-1), and 2) through the USB on the Starter Kit. By
connecting a 9-15V power supply to the DC connector or the USB device on the Starter
Kit, the MEB II, Display Daughter Board and the Starter Kit will receive the proper
voltages. However, if the application plans to use multiple features of the MEB II, it is
recommended to use a 9V to 15V DC power supply.

Note: Refer to Appendix A. “Board Layout and Schematics” and Appendix
B. “Bill of Materials” for the schematics and manufacturer and part
number information of the hardware components used in the Multimedia
Expansion Board II (MEB II) and the 4.3" WQVGA PCAP Touch Display
Board.
CAUTION
When connecting the Multimedia Expansion Board II (MEB II) to a starter kit, do not
have power applied to either the starter kit or the DC power supply. Failure to heed this
caution could result in hardware damage.
