Overview
The Camera Cube is designed to let makers quickly start using ESP32 camera modules without complex setup. It integrates the Camera-M module and the Basic expansion board. Based on the ESP32 chip, featuring 4MB of Flash and 8MB of PSRAM. It uses an OV2640 image sensor capable of capturing images at up to 1600×1200 resolution and supports real-time video streaming over Wi-Fi. Breakout ports include 10 GPIOs, UART, and I2C interfaces. The Camera Cube also features a built-in USB-to-serial port, SD card slot, and battery charging circuit, and comes with a 300mAh lithium battery.
The Camera Cube has an easy-to-expand enclosure design and a LEGO-compatible bracket, making it ideal for quick product prototyping. It supports popular development platforms such as Arduino, PlatformIO, and ESP-IDF.
The Camera Cube comes pre-loaded with test firmware. To run a test:
- Turn the bottom power switch to the ON position.
- Use your phone to scan for Wi-Fi networks. Find the network name starting with
Node-and connect to it (password:nodenode). - Open a web browser on your phone and go to
192.168.4.1. - View the video stream or modify network settings on the webpage.
