Hobby-level microcontrollers are finally getting big and powerful enough to start handling camera modules that historically would have required a full computer or FPGA to handle.
The RP2040 and ESP32-Sx series of chips, for example, have enough pins to communicate with the 8-bit data output, DMA to quickly grab a frame, and the necessary RAM to buffer a raw snapshot. Now all we need is a nice camera module to make interfacing easy!
This Adafruit OV5640 Camera Breakout with 120 Degree Lens has a nice quality OV5640 camera with a 5 Megapixel sensor element, 120-degree wide angle lens, and all the support circuitry you need. Adafruit looked at existing camera modules and while this breakout board is backwards compatible, we made some improvements:
Product Dimensions: 35.7mm x 23.0mm x 17.5mm / 1.4" x 0.9" x 0.7"
Product Weight: 4.6g / 0.2oz
