For connecting the DLP2010 (.2 WVGA) DMD, DLPC34xx controller, and DLPAxxxx PMIC, see the reference design schematic and board layout TIDA-00325. When a circuit board layout is created from this schematic, a small circuit board is possible. Follow the layout guidelines to design a reliable projector.
It is typical for an optical engine manufacturer to supply the optical engine that includes the LED packages and a mounted DMD. These manufacturers specialize in designing optics for DLP projectors. There exists production-ready optical modules, optical module manufacturers, and design houses.
