LightCrafter
This user's guide presents an overview of the DLP
a general description of the main features and functions. It explains the first steps to get started, and shows a
detailed description of onboard LEDs, connectors, and overall EVM assembly.
The EVM can be used by itself to display a DLP LightCrafter Display test image or in combination with a low-end
processor including the Raspberry PI 4B.
This guide provides the user with further information on how to successfully connect the EVM to the Raspberry
PI 4B and get the Raspberry PI content projected on the wall.
