STMicroelectronics STEVAL-66GYMAI1

Overview

STEVAL-66GYMAI1 from STMicroelectronics is a hardware evaluation kit for the VD66GY global-shutter RGB image sensor, featuring native MIPI CSI-2 (1–2 lanes) output, I²C control interface, 22-pin FFC connector (Hirose FH12-24S-0.5SH(55)), 1.53 MP resolution (1124 × 1364), and integrated M12 lens holder with AB02816MG 2.8 mm f/1.6 lens for PC or embedded vision prototyping.

For engineers reviewing the STEVAL-66GYMAI1 datasheet, STEVAL-66GYMAI1 pinout, STEVAL-66GYMAI1 application, or STEVAL-66GYMAI1 equivalent, this kit enables rapid sensor integration on Linux-based embedded platforms via pre-validated drivers and supports PC-based evaluation when paired with ST's EVK Main kit and GUI software.

Technical Context

The kit implements the VD66GY sensor in a ready-to-deploy board-level form factor, with fixed MIPI CSI-2 signaling (RAW8/RAW10), configurable lane count, and I²C register access for exposure/gain/control. The 22-pin FFC interface carries power, ground, MIPI data/lane clocks, I²C SDA/SCL, and optional lighting control signals.

Optical architecture centers on an M12-threaded lens holder supporting interchangeable lenses down to 1/4″ format and ≤2.61 µm pixel size compatibility; chief ray angle is specified at 30° at 4.61 mm diagonal, requiring CRA-matched optics for optimal vignetting control.

Key Specifications

FAQ

Does STEVAL-66GYMAI1 include Linux drivers?

Yes - ST provides free, production-ready Linux kernel drivers for the VD66GY sensor on st.com, supporting MIPI CSI-2 enumeration and RAW8/RAW10 streaming on ARM-based platforms including STM32MP1 and NXP i.MX series. Drivers are validated against mainline-compatible BSPs and include device tree bindings.

Can STEVAL-66GYMAI1 operate standalone without the EVK Main kit?

No - the kit outputs raw MIPI CSI-2 video and requires a host processor with MIPI CSI-2 receiver capability (e.g., Raspberry Pi Compute Module 4, NVIDIA Jetson Nano). USB output is only enabled when connected to ST's EVK Main kit, which handles protocol translation and power management.

What lens specifications must replacement optics meet?

Replacement lenses must have M12 × 0.5 threading, ≤13 mm back focal length, ≥1/4″ optical format, and chief ray angle ≤30° at 4.61 mm diagonal. Pixel-level resolution must support ≥1124 × 1364 array size; Alaud AB02816MG serves as the reference optical baseline.

Is the default lens permanently attached?

No - the AB02816MG lens is nonglued and mechanically secured only by the M12 holder; users may manually adjust focus or remove it entirely to install alternate optics. Holder screws allow secure repositioning without adhesive or soldering.
