= Key Features =
High Frame Rate - 30fps for smooth image capture [citation:1]
Flexible Output - Supports RGB565, YUV, and Raw formats [citation:1]
Automatic Controls Builtin exposure, gain, white balance [citation:1][citation:6]
Low Power Mode - <20µA standby current for battery projects [citation:4]
SCCB Interface I2Clike control for adjusting image settings [citation:1]
√ No FIFO buffer (standard); assumes a microcontroller to read data directly [citation:3]
√ Widely used with Arduino, STM32, and ESP32
√ Comprehensive online libraries and resources available
Interfacing with an Arduino UNO is more challenging due to RAM and pin constraints. An Arduino MEGA or ESP32 is often recommended [citation:3]. The camera uses multiple signal lines:
| Signal | Description |
|---|---|
| VSYNC | Frame synchronization [citation:5] |
| HREF | Line valid signal [citation:5] |
| PCLK | Pixel clock [citation:5] |
| XCLK | External clock input (requires external signal) |
| SIOD/SIOC | SCCB data and clock for configuration [citation:3] |
| D0-D7 | Parallel data bus [citation:5] |
> The sensor uses parallel communication, consuming many I/O pins and requiring the generation of an XCLK signal [citation:3]
