A picture says more than a thousand words. This is why the world is moving away from text to images and videos. We, as Makers, can profit from this movement because we get dirt cheap hardware to play with. And if it works with an ESP32, even better. Time for a closer look.
I am a proud Patreon of GreatScott, Electroboom, Electronoobs, and others.

In this video I will:
Compare the features of the four boards
Try to get all of them working. Here we will see that we have to overcome the usual obstacles
Try to use the new class of I2S MEMS microphones presented in my last mailbag. Two of the modules have such a microphone included
Try out two sorts of camera lenses
