GENERAL DESCRIPTION
The evaluation system is composed of a motherboard and
a daughterboard. The motherboard provides the I
from the computer USB port and generates the I/O voltages
and digital high and low signals for the daughterboard.

Unit for Imaging Modules
The motherboard features a 3.3 V regulator (VBOARD) a 3.7 V
regulator (VBATT) and a 2.0 V regulator (VDDIO). VDDIO is
the digital I/O voltage supplying the I
pins. VBOARD is the motherboard logic supply while VBATT
provides power to the daughterboard. Jumpers on the top left
of the motherboard define whether the internal regulators are
supplied from the USB port or from external supplies connected to
J10. The VBUS line from the USB connector powers the mother-
board regulators when Jumper LK8 to Jumper LK10 are in the
USB position. Connector J10 provides supply voltages for the
motherboard and daughterboard when Jumper LK8 to Jumper
LK10 are in the EXT position.
The daughterboard contains numerous jumpers, LEDs, and test
points for easy evaluation and monitoring of the board.
