FlexLight LC4500

The Flexlight 4500 product family is a production-ready, full-featured implementation of the Texas Instruments LightCrafter4500 chipset, which includes the DLPC350 and 0.45″ WXGA DMD.

Need to place the DMD far away from your electronics? Want to quickly support image downloads without having to flash new image data each time? Prefer direct Ethernet support? The LC4500 offers more than TI’s standard kit.

Like the Texas Instruments LightCrafter™ 4500, Keynote Photonics LC4500 projectors and electronic kits are based on Texas Instruments’ .45” WXGA DMD (DLP4500FQD, DLP4500FQE and DLP4500NIRFQE). The LC4500 controller provides a direct interface for the popular BeagleBone Black development platform based on a AM335x ARM® Cortex A8 processor, providing users the ability to stream patterns created real time into the projector. This interface connector can also be used for custom FPGA designs and has access to the system I2C and other vital trigger and control signals from the main board.

A complete streaming pattern application and API is available for the Beaglebone Black that comes with its own graphical user interface that can support Windows, Linux or Mac.


A MSP430 micro-controller is integrated on the main control board, allowing customized configurations and modes of the DLP chipset. This versatile controller offers single-color or 3-color display. Common applications for these kits are 3D printing, 3D measurement, and NIR spectroscopy

The Flexlight LC3010-H6 is a production-ready, full-featured implementation of the Texas Instruments DLP3478, DLP3010 and DLPA3000. 

Expected general availability: July, 2019. Contact us for for early access.

This DLP-based platform provides fast development for end equipment requiring small form factor, lower cost, and intelligent, high-speed pattern display. It features the 0.3″ 720P HD chipset (DLP3010) and provides a variety of embedded functionality such as: structured light pattern projection, intelligent lighting, wavelength selection and portable display.

LC3010-H6 Concept

Developers can create, store, and display high-speed pattern sequences through a USB-based application programming interface (API) using Keynote’s API.  Keynote provides an enhanced easy-to-use graphical user interface (GUI) to aid in the control and development of various pattern sequences and other operating modes.
