Yahboom ESP32-S3 WiFi Camera Module Lite Version 2MP AI Vision Board, AP+STA, UART/IIC, Type-C

Overview

ESP32 WiFi Camera Module Lite Version is an ESP32-S3-based AI vision solution for DIY project development and electronics design competition. It integrates WiFi/BT (BT 5.0), an onboard 2MP CMOS camera, antenna support, custom buttons, and serial + IIC interfaces. The module can operate as a minimum system board for wireless video transmission over LAN (via its own hotspot) or connect to a router network, and it can be installed on a smart car or robot with an optional 2-DOF PTZ for real-time video transmission and AI visual recognition.

A dual-board architecture is supported (core board + optional communication board). The communication board provides a Type-C interface for writing code, and PH2.0 IIC and serial interfaces.

Key Features

• Wireless video transmission; supports Web camera monitoring and APP viewing.
• Two working modes: AP mode (module automatically sends out WiFi hotspots) and STA mode (module connected to WiFi router). AP+STA can be switched, and can be enabled at the same time according to application needs.
• AI intelligent vision recognition (built-in algorithms): cat/dog detection, face detection, color recognition, person recognition, QR code recognition.
• Built-in ESP32-S3 chip: low-power dual-core 32-bit CPU, maximum 240MHz main frequency, computing power about 600MIPS.
• 2MP HD camera output; CMOS image sensor technology.
• Interfaces: serial communication and IIC communication (IIC/UART interface noted); recognition objects can be switched via serial port or IIC communication.
• Onboard custom buttons: reset button and customizable programming button.
• Firmware update support: via Type-C (with communication board) or via USB-to-TTL module (separate module).
• External antenna support; video image transmission up to 20M (as stated).
• Compatible with multi-master (supports multiple external master controls); tutorials for multiple MCUs (STM32, micro:bit, AR, Raspberry Pi Pico, MSPM0, etc.).
• Development support: provides codes, detailed tutorials and schematics; ESP-IDF development environment tutorials and AI recognition case source code.

Details

Built around the ESP32‑S3, this WiFi/BT camera module combines a 2MP sensor with AI vision functions for DIY robots, smart cars, and embedded projects.

A dual-board setup is supported: a compact camera core board plus an optional Type‑C communication board for convenient programming and expansion.

Choose the standalone camera module or add the Type‑C communication board and 2‑DOF PTZ kit depending on how you plan to program and mount it.

Use it for real-time video streaming over WiFi plus built-in recognition options such as QR codes, faces, colors, and common objects.

Onboard buttons and common interfaces (UART/IIC) make it easy to integrate the camera module into custom controllers and robotics platforms.

Development resources target popular controllers and the ESP‑IDF environment, supporting fast prototyping from demos to full applications.

External antenna support helps improve wireless stability for LAN video transmission and remote monitoring use cases.

Add the 2‑DOF PTZ to pan/tilt the camera and control viewing direction through an app-based remote interface.

Switch between app viewing and browser monitoring to fit your workflow, from quick tests to desktop dashboards.

AP mode creates a direct hotspot connection, while STA mode joins an existing router network for flexible deployment.

Typical setups connect the camera stream to a phone or PC for monitoring while a separate controller handles robot motion over serial/IIC commands.

Yahboom ESP32 WiFi camera projects are supported with downloadable code, documentation tutorials, and a 3D model file for DIY builds.

The ESP32-S3 WiFi camera connects to MSPM0 or STM32 controllers via 5V, GND, and UART TX/RX serial lines for basic communication.

The Yahboom ESP32-S3 WiFi camera module can be wired to Raspberry Pi Pico, Arduino, or micro:bit using TX/RX, power, and GND connections.

The ESP32-S3 WiFi camera module includes a labeled pinout for 5V/GND power, UART TX/RX, reset, and camera signal connections.

The Yahboom ESP32-S3 WiFi camera module uses a 2.4GHz FPC antenna and runs on 5V power, with a reset button and AP/STA modes listed.

The ESP32-S3 camera communication board measures 40×27×1.6 mm and uses 2.54 mm header pitch with labeled 5V/TX/RX/GND and 5V/SDA/SCL/GND connections.

2DOF PTZ dimensions and listed servo voltage/current details help plan mounting space and power for a Yahboom ESP32-S3 WiFi camera build.
