STEVAL-EVK-U0I Data Brief
EVK Main: Hardware USB Kit for Evaluating ST BrightSense Image Sensors on a Computer
Product Overview
The EVK Main is a versatile hardware kit enabling the evaluation of any ST BrightSense image sensor or associated evaluation promodule on a computer. This comprehensive evaluation solution includes an EVK Main board with USB-C output and a mechanical holder for stable image capture.
Leveraging its well-thought-out modular design, the EVK Main can be used and reused in various ways to perform image sensor evaluation. With its two input connectors, it offers the user the flexibility to evaluate image sensors either as turnkey evaluation promodules or combined with any off-the-shelf M12 lens.
Evaluating ST BrightSense image sensors as turnkey promodules is instant by plugging any promodule (e.g., CAM-56G3, CAM-66GY, CAM-55G0, CAM-55G1) onto the common flex-to-board connector at the bottom left of the board. Evaluating sensors with the ability to fine tune the lens is also easy by plugging one of the S-Board solutions from ST and its included ribbon cable into the FFC/FPC connector at the top left of the board. This dual input system enables reusing the exact same kit at different stages of the development process or for evaluating different products.
The mechanical holder embedded in the kit provides additional flexibility for evaluation in three different mechanical configurations. It can be used on a flat surface such as a desk, inserted on a laptop as a webcam leveraging the slit of its V-shape design, or fixed on a tripod using the tripod connector on the bottom face of the holder.
Featuring USB3 output, it provides immediate plug-and-play connection to computers and laptops. Combined with the STSW-IMG501 free evaluation software from ST, the EVK Main offers a quick and effortless evaluation experience of ST BrightSense image sensors.
