Unit Camera DIY Kit
Description
The Unit Camera DIY Kit is a "self-assembly" ESP32 WiFi camera kit. The kit comes standard with two lens modules: a wide-angle fisheye and a regular perspective lens, both using the OV2640 image sensor, supporting a maximum output of 2M pixel images. It supports image transmission via WiFi or serial port. The DIY shell design allows you to enjoy the fun of assembling a model while obtaining a powerful camera. The compact size, high resolution, and focus adjustment make it suitable for various IoT imaging applications.
High Flexibility:
- Supports lens focus adjustment
- GROVE expansion interface, programmable RGB light
Plug and Play:
- Comes with pre-installed image transmission firmware, supports UART/WIFI image transmission
- Integrated image parameter API interface (white balance, exposure, gain, size, etc.)
- Comes with PC-side debugging tools
- Supports one-click calling on the UIFlow graphical programming platform, cloud transmission
- Fully compatible with mainstream development platforms such as Arduino and ESP32-IDF
