RTCC
VCC-IO
When interfacing with 3.3v external logic, connect VCC-IO to the 3.3v supply of the external logic;
otherwise, connect to the VCC to drive out at 5v CMOS level. This pin must be connected to VCC
from the target electronics or EXTVCC.
EXTVCC
PORTVCC if the module is to be powered by the USB port (typical configuration).
PORTVCC
USB port (typical configuration). 500mA is the maximum current available to the DLP-245SX and
target electronics if the USB device is configured for high power.
