Hi I have a project to make a spy camera pen, so a small circuit with a camera ("Compact Camera Module"), a microcontroller and an sd card ending after several searches on google, on forums and sites, I understand that it's not as simple as i thought, i looked for how to use a small camera like those found in phones with a programmable microcontroller like attiny or atmega but i learn that they are not not powerful enough then I thought of the ESP32 Cam but its dimensions do not suit me and I do not see the point of buying something already manufactured, so I wonder which programmable microcontroller to choose to be able to control a camera and make the circuit myself or otherwise modify the circuit of the ESP32 Cam to give it a suitable size. My first concern is the camera and later I will see for the sd card. I don't really know how to go about it and I want to learn more about microcontrollers and SoCs/PSoCs. (Sorry for my level of English).
A camera like that, but I don't know if it's possible and if I have to use another circuit for the camera or if I can directly use it with a microcontroller.
