5 Light Engine

The optical engine in the EVM is developed by Young Optics and is production ready. The light engine consists of the following components:

  • DLP230NP (0.23-inch 1080p DMD)
  • OSRAM red (KR CSLNM1.23_EN), green (KP CSLNM1.F1_EN), and blue (KB CSLNM1.14_EN) LED
  • This light engine interfaces with the EVM using DMD pin mapping Option 1. For more information about the DMD interface, see the DLPC3436 data sheet.

For more information on the LEDs used in this optical engine (KR CSLNM1.23_EN, KP CSLNM1.F1_EN, and KB CSLNM1.14_EN) contact OSRAM using the provided mailing list: dlp-pico-osram@list.ti.com.
