Camera-1

Overview

Camera-1 is a camera module 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.

The module is optimized for scalability. Breakout ports include 10 GPIOs, along with UART and I2C interfaces. An onboard DC-DC converter provides 5V and 3.3V power outputs, each capable of delivering up to 500mA. Additional features include a built-in USB-to-serial interface, an SD card slot, and battery charging management. By shorting the designated solder jumper pads, you can enable battery voltage detection and camera power control.

Camera-1 is particularly suitable for applications that require camera functionality along with multiple I/Os for controlling peripheral modules. It can be programmed using popular development platforms such as Arduino, PlatformIO, and ESP-IDF.

The module comes pre-loaded with test firmware. To run a test:

1. Power the development board via the USB port or the lithium battery interface, and switch the power button to the ON position.
2. Use your phone to scan for Wi-Fi networks. Find the network name starting with Node- and connect to it (password: nodenode).
3. Open a web browser on your phone and go to 192.168.4.1.
4. View the video stream or modify network settings on the webpage.
