Current shipped module: The electrical parameters above apply to the current shipped 60°/15cm OV5640 module. NE101 uses AVDD 2.8V, DVDD 1.5V, and DOVDD 2.8V; the 1V2 schematic net name is a DVDD labeling error. RESET is active low, and PWDN is active high. The OV5640 MCLK (XVCLK) sensor specification is 6–27MHz, with 24MHz typical; the sensor-side logic domain follows DOVDD (2.8V on NE101). The current NE101 production configuration uses 5MHz MCLK. This is a board-level configuration validated for this board's interconnect and signal integrity; it is not the generic module-rated input range.

Usage Instructions

Installation Steps

1. Hardware Connection:

   • Connect the FPC connector (38.5×12.5mm, 24Pin@0.5mm pitch) to the main board.
   • Ensure power lines (AVDD/DVDD/DOVDD) and ground lines (AGND/DGND) are correctly connected.

2. Initialization Configuration:

   • Write register configurations via the SCCB interface (SDA/SCL) (refer to Register Tables in the OV5640 datasheet).
   • Configure FOV, exposure time, gain, and other parameters.

3. Image Output:

   • Enable the DVP interface (Digital Video Port) and set the data format to YUV422 or RGB565.
   • Read image data via VSYNC/HREF sync signals.

Precautions

• ESD Protection: Wear an anti-static wrist strap during handling.
• Power Supply Stability: Ensure AVDD voltage fluctuation is within ±5%.
• Thermal Design: Consider a thermal dissipation solution for prolonged operation.
