Pick up almost any modern embedded camera datasheet and you will meet two acronyms within the first page: DVP and MIPI. They describe how the image gets from the sensor to your processor, and choosing the wrong one is one of the most expensive mistakes in a camera project. It can mean a processor that physically cannot connect to the sensor, a board with far too many traces, or a video stream that stutters because the link is too slow. This guide explains the difference in plain terms, then walks through real module choices for microcontroller boards, IoT devices, doorbells, wildlife cameras and drones. It comes from the team at Shenzhen Brilliant CMOS Technology Co., Ltd., where we design and supply OEM and ODM camera modules, so it focuses on the decisions that actually cause problems in development. In this guide What a CMOS sensor does, and what the module adds DVP vs MIPI: the core difference Which interface does your processor support?

What a CMOS sensor does, and what the module adds The cmos sensor is the chip that turns light into an electrical signal. Millions of tiny light-sensitive pixels each measure how much light reaches them, and the chip reads those values out as image data. CMOS sensors dominate modern cameras because they are low-power, fast and cheap to manufacture, and they can integrate image-processing functions on the same chip. But a bare sensor is not a camera. A camera module adds everything else you need to get a usable picture: A lens matched to the sensor, with the right field of view and focus type A focus mechanism, either fixed focus or an autofocus actuator An infrared filter (or an IR-cut arrangement) so colours look natural A flexible cable or connector to link the module to your board A tested, tuned assembly, so every unit behaves consistently Buying a module rather than a bare sensor saves months of optical design, alignment and tuning. That is exactly why embedded teams choose modules. 2. DVP vs MIPI: the core difference DVP (Digital Video Port) is a parallel interface. It sends pixel data across a bundle of separate wires at once (commonly 8 or 10 data lines), accompanied by a pixel clock and synchronisation signals for lines and frames. MIPI CSI-2 is a serial interface. It sends data as high-speed differential pairs called lanes, typically one, two or four, plus a clock pair. Fewer wires carry far more data. Here is what that means in practice:   DVP MIPI CSI-2 Signal type Parallel, single-ended Serial, differential lanes Typical pin count High (often 20 or more connections) Low (a few signal pairs) Bandwidth Modest High, scales with lanes Typical resolutions Up to a few megapixels, lower frame rates Multi-megapixel up to 4K and beyond Board design Easy to prototype, but many traces Needs careful controlled-impedance routing Processor support Common on microcontrollers Common on application processors and newer SoCs Cable length and noise Short runs preferred Better for longer runs and noise immunity The short version: DVP is simple and widely supported on small processors but limited in speed and wire-hungry. MIPI is the modern choice for high resolution and frame rate, but needs a processor with a MIPI CSI-2 receiver and more careful PCB design. 3. Which interface does your processor support? This is the question to answer first, because it decides everything else. A camera interface is a hardware block on the processor. If your chip does not have a MIPI receiver, no software can add one. Many microcontrollers provide a parallel camera interface, so DVP modules connect directly. Application processors and modern SoCs, such as those on single-board computers and smart devices, typically include MIPI CSI-2 receivers. Some processors have both, which gives you the freedom to choose by performance and cost. Always check the exact part number in the manufacturer’s reference manual: not just the family. Interface availability can differ between variants of the same product line. If your processor has only DVP but you need MIPI-class sensors, discuss bridge or alternative architectures with our team early. 4. OV5640: the versatile 5MP workhorse If you search for an OV5640 camera module, you are looking at one of the most widely used 5-megapixel sensors in embedded design. Its popularity comes from solid image quality for its class, broad software support, autofocus options on many modules and a long history in products. Our 5MP OV5640 CMOS sensor DVP camera module with a 24-pin interface is a straightforward choice for projects with a parallel camera port. It also serves as a compact camera module for products where space and board area are limited, while still giving a clear step up from VGA and 2MP options. If your design needs both interface options or an IR-cut filter, see our 5MP fixed-focus OV5640 / OV5648 OEM MIPI/DVP IR-cut camera module, which is offered for OEM customisation across interface styles. What to check on any OV5640-based module Frame rate at full resolution. Full 5MP frame rates on a parallel interface are lower than at reduced resolutions, so confirm the mode you need. Focus type. Fixed focus is robust and cheap; autofocus helps when subject distance varies. Connector pinout. Confirm the 24-pin pin order against your board to avoid a costly layout error. Clock and power requirements. The sensor needs an input clock and several supply voltages, so review them against your power design. 5. STM32 and microcontroller camera projects Searching for an STM32 MIPI camera usually means one of two things: someone using an STM32 microcontroller with a camera port, or someone choosing a sensor for a newer STM32 part that supports a serial camera interface.
