Adafruit OV5640 Camera Breakout - 72 Degree Lens with Autofocus

Product ID: 5840

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....
