STMicroelectronics STEVAL-56G3MAI1

Overview

STEVAL-56G3MAI1 from STMicroelectronics is a hardware evaluation kit for the VD56G3 monochrome global-shutter image sensor, featuring native MIPI CSI-2 (1–2 lanes) output, I²C control interface, 22-pin FFC connector (Hirose FH12-24S-0.5SH(55)), and integrated M12 lens holder with AB02816MG 2.8 mm F/1.6 lens. It enables rapid sensor integration on embedded Linux platforms.

For engineers reviewing the STEVAL-56G3MAI1 datasheet, STEVAL-56G3MAI1 pinout, STEVAL-56G3MAI1 application, or STEVAL-56G3MAI1 equivalent, key selection factors include MIPI CSI-2 lane count support, RAW8/RAW10 data format compatibility, FFC cable length (10 cm), board dimensions (30 × 35 × 8 mm), and lens mount flexibility (M12 or smaller).

Technical Context

The kit implements a complete optical-electronic evaluation path: the VD56G3 sensor outputs 1124 × 1364 monochrome image data via configurable 1- or 2-lane MIPI CSI-2, while I²C handles configuration and status readback. The 2.61 µm pixel global shutter supports motion-free capture in industrial inspection.

Optical design centers on a 1/2.7″ format, 110° horizontal FOV lens with 26° chief ray angle matching the sensor's CRA profile; mechanical compatibility extends to any M12-threaded or smaller lens meeting minimum 1/4″ optical format and ≤13 mm back focal length requirements.

FAQ

What operating systems are supported for software integration?

Linux-based embedded platforms are natively supported via free drivers available on st.com. The kit also enables Windows PC evaluation when paired with ST's EVK Main board and the provided GUI evaluation software - no custom driver development is required for either environment.

Can the default lens be replaced, and what are the optical constraints?

Yes - the AB02816MG lens is non-glued and user-focusable. Replacement lenses must use M12 × 0.5 threading, support ≥1/4″ optical format, maintain ≤13 mm back focal length, and match the sensor's 26° chief ray angle at 4.61 mm diagonal to avoid vignetting.

Is USB output possible without additional hardware?

No - USB functionality requires connection to ST's separate EVK Main evaluation board (sold separately), which provides USB bridge, power regulation, and host-side firmware. The STEVAL-56G3MAI1 itself only outputs MIPI CSI-2 and accepts I²C commands.

Does the kit include lighting or illumination control?

The board features a dedicated connector for optional lighting boards, but no LED driver or illumination source is included. Users may attach compatible third-party lighting modules via this 2-pin header to synchronize illumination with global shutter exposure timing.
