The LC4500 NIR EKT controller electronics kit facilitates development and production of infrared DLP-based products using customer-provided optics.  The kit includes DMD and illumination control electronics along with the DLP4500NIRFQE DMD mounted on a separate board and connected with a 7cm flexible cable.  An optional 30 cm cable is available to allow more flexibility in positioning  the drive electronics away from the DMD and optics.

The Flexlight 4500 product family is a production-ready, full-featured implementation of the Texas Instruments DLP4500 chipset which includes the DLPC350 structured light controller and 0.45″ WXGA DMD.   The system is fully compatible with the TI LightCrafter 4500 API developed for the DLP4500 chipset.

Optional Pattern Expansion Module
An optional Pattern Expansion Module (PEM) add-on is available, which is based on the Beagle-Bone development platform and is installed on headers added to the LC4500 controller board.  It expands the functionality of the LC4500 controller board by adding:
  • Ethernet interface for control and communication
  • Ability to operate pattern sequences at a fixed frame rate (50Hz per 24-bit frame) regardless of the number of patterns or bitplanes in the pattern sequence
  • Ability to update individual stored patterns without reprogramming the entire DLP4500 chipset firmware
  • Separate graphical user interface including PEM and general chipset controls

If desired a PEM-equipped controller board may be operated in the same way as one without a PEM using the standard GUI and USB interface with no loss of functionality or performance.

Note:  The headers for the PEM are not installed by default on the LC4500 controller board.  It is recommended that the PEM option be ordered at the same time as the rest of the electronics kits.
