Ding dong! Hear that? It's the PiCowbell ringing, letting you know that the new Adafruit PiCowbell OV5640 Camera Breakout with 120-degree Wide-Angle Lens is in stock.
This is a quality OV5640 camera with a 5 Megapixel sensor element, a 120-degree wide-angle lens, plus all the support circuitry you need to start taking pictures with your Pico or Pico W. You can grab raw RGB images for image analysis, or use the built-in JPEG encoding to save images to an SD card or upload them to adafruit.io.
The RP2040 chip has a fast PIO interface peripheral and enough memory to interface with 'DVP' (8-bit parallel digital) cameras. These camera sensors have 8 image data pins, Pixel Clock, H Sync and V Sync signals, plus an I2C configuration interface and a Reset plus power down pin. That does mean a lot of GPIO is used! But we still have 6 GPIO pins available even after adding an SD card and shutter button.
Camera PiCowbell Features:
Interface for OV5640 Camera module
VSync: GPIO 0
Power Down: GPIO 1
HSync: GPIO 2
Pixel Clock: GPIO 3
SDA/SCL: GPIO 4 and GPIO 5
8-bit Digital: GPIO6 through GPIO 13
Reset: GPIO 14
VMotor connected to 3.3V for auto-focus modules
Micro SD Card:
SPI on GPIO 16, GPIO 18 and GPIO 19
Chip select on GPIO 17
Optional SD Detect on GPIO 15
Shutter button on GPIO 22
Reset button
16 MHz 'XClock' generated by the onboard oscillator
Stemma QT port for I2C on GPIO 4 / 5
This module does not have auto-focus capability, it is a fixed 'infinite' focus module.
Each order comes with an assembled PCB, camera sensor, and two pieces of 20-pin pin header. You will need to solder in the header yourself, but it's a quick task.
Since this board has the camera pointing 'up', it's best to use our PiCowbell 'doubler' to have the Pico on one side with the BOOT button accessible, and then the camera on the other side. Or you can 'stack' the camera 'bell on top, best when you don't need easy access to the BOOT loading button.
Or, for a compact package, you can...
Use the Pico Stacking Headers if you want to be able to plug into a breadboard or other accessory with sockets. Solder these onto the Pico so that the camera is on top.
Use the Pico Socket Headers if you want to plug directly in and have a nice solid connection that doesn't have any poking-out bits. Ditto, solder these into the Pico and plug the camera on top.
