Hello,

I'm looking for an MCPU that can interface with a camera, and wireless. My objective is to grab the video data and send it over the wifi signal. One wifi device I am looking at is the 88W8801 which can be connected using a couple high speed interfaces (USB, SPI). Anyone have experience with an MCPU that can offer a recommendation?

Have you seen the ESP32CAM? Inexpensive, with camera, WiFi, easy to program

I haven't seen that one. Thanks for the recommendation. I am going to order a couple and see if they can pump 720p at 30FPS, which is my target resolution and frame rate.

Table from here (German, sorry, but very informative). Here's another page in English, also very good.

30 fps: might be possible, see here. Will depend on resolution and quality. My own experiments resulted in more like 5 - 10 fps :( But I had only tinkered with the camera and by no means done any optimization. Also used max frame size, not 720p.

I saw that same thread. I am going to give it a try. It was cheap enough. If that doesn't work I may try an STM32H7 series. I have a nucleo that I can try. They are quick little things, but not sure if they are good enough for this.
