GROUND
SWVCC
and Q1 MOSFET power switch. R5 and C3 control the power-up rate to help limit inrush current.
GROUND
No connect
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-245PB-G
and target electronics if the USB device is configured for high power.
