Version 1 PCB

Published on 2021-10-25 in Camera Shield for S2 Mini.

This is the first attempt at this shield, and it’s mostly based on guesswork, datasheet, schematic for the ESP32 Cam board, and some bad quality images of the pinouts I found online. I have absolutely no idea if it will work, but I can try. The design is pretty dense:

I didn’t feel like fixing the angles of all the traces, so you will have to suffer. The render doesn’t look bad:

There are two voltage regulators, each with its own capacitor, two resistors for I2C pull-ups, a resistor to pull-down the enable pin on the camera, and a 14pF capacitor on the PCLK line, no idea why, but ESP32 Cam had it, so I copied it. And of course the camera socket itself, which is a fun 0.5mm-pitch footprint.
