This tiny little camera module can be a pretty neat project addition, it is just like our other JPEG cameras (same chipset/software), but much smaller and slimmer. It was designed to be used in security systems and does two main things - it outputs NTSC color video and can take snapshots of that video (in color) and transmit them over the TTL serial link. You can snap pictures at 640x480, 320x240 or 160x120 and they're pre-compressed JPEG images which makes them nice and small and easy to store on an SD card. Perfect for a data-logging, security, or photography project.
One nice thing about this particular camera is all the 'extras' that come with it. For example it has auto-white-balance, auto-brightness and auto-contrast taken care of for you as well as motion detection built in! That means you can have it alert your project when something moved in the frame. The lens is manually adjustable, it has a 1-15 meter focal distance by default which is good for most projects.
We also carry a much larger, but enclosed weather-proof version
Using the module is pretty easy and only requires two digital pins (or a TTL serial port) - by default it transmits at 38400 baud. Of course we wouldn't just leave you with a datasheet and a 'good luck', we even spent a lot of time researching the module and DSP to make really nice libraries for both Arduino & CircuitPython, with example code that shows how to change the image size and compression quality, detect motion, control the video output stream, etc. That and more is available in our very detailed tutorial that will help get the most use out of your camera.

Jargon buster
Plain-language definitions for the technical terms used above.
- Auto-white-balance
- A camera feature that adjusts colour so white objects look closer to white under different lighting. It matters because it reduces the amount of image processing your project needs to do, especially when lighting changes outdoors.
- baud
- Baud is the signalling rate of a serial connection, often used as the speed setting for UART communication. Matching the baud rate matters because both connected devices must use the same setting for readable data.
- CircuitPython
- A beginner-friendly version of Python designed to run directly on microcontroller boards. If a product supports CircuitPython, you can often program it by copying code files onto the board rather than setting up a more complex toolchain.
- DSP
- Digital signal processing means using software or hardware to analyse or modify signals such as audio, vibration, or sensor readings. A board suited to DSP is useful when a project needs fast maths for filtering, synthesis, or real-time signal analysis.
- JPEG
- A widely used compressed image file format for photographs, where some detail is discarded to keep file sizes small. When a device produces JPEG output, the images are already compressed, making them easier to store on an SD card or send over a slow link than uncompressed raw data.
- Motion detection
- The ability to sense that something has moved, either by comparing successive camera frames or by using a dedicated sensor such as a PIR (infrared) or radar module. When a product lists motion detection, movement can be used as a trigger so a system only acts or records when there is activity rather than running continuously.
- TTL serial
- A simple serial data connection that uses microcontroller logic-level voltages (typically 3.3 V or 5 V) rather than the higher, inverted voltages of computer RS-232. When a device lists TTL serial, it can usually wire straight to a microcontroller's UART pins or to a USB-to-TTL serial adapter, but it needs a level converter before connecting to a true RS-232 port.
