…the camera uses a KAI4000 image sensor. This is a 90s/00s era image sensor. The sensor effectively operates as 4 independent image sensors. For the fastest/most consistent readout you probably want to acquire images from all 4 quadrants at the same time. As such this camera duplicates analog and acquisition circuits four times. An AD9225 ADC is used, and four of these are present under shields.
A bunch of Xilinx FPGAs are used to acquire data from the ADCs/send it to a host computer.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
