Re: Studying ESP-EYE V2.1 ref design. A few questions...

Great! Thanks @ESP_Sprit! I guess I can skip a few of them since I could do a solder jumper if I need to maintain separate net names across connections and still have the option to more easily cut the trace or solder it back. For anyone not comfortable with that, a 0 ohm resister is easier.

Re: Studying ESP-EYE V2.1 ref design. A few questions...

Thanks @username!

I'll read more on this especially on the EMI reduction. So as a designer you can have test engineers test and vary the resistance until they achieve best results?

Studying ESP-EYE V2.1 ref design. A few questions...

So I'm trying to make my own board with a camera. I am using ESP-EYE reference design: https://www.espressif.com/en/support/documents/technical-documents?keys=EYE In the design, if you go to the camera section, you see lots of 0 ohm shunts. Screenshot 2021-08-28 181536.jpg Here is a photo of the boa...

Re: Setting up to do projects on an ESP32-CAM board

Wow that was obvious the logo but I missed it! Thanks for pointing it out! These are mental blocks I think, seeing a logo but actually not noticing it at the same time. I think the older esp32-cam boards have espressif logo but not sure if it was fake. The older boards also do not break out the rese...

Re: Setting up to do projects on an ESP32-CAM board

Thanks. So do you mean this ESP32-S is not an espressif product or it is not ESP32-solo, maybe both if first one is false ( :lol: )?

Re: Setting up to do projects on an ESP32-CAM board

OK thanks. So is this ESP32-S even an espressif product? I guess not. I should really have googled the part but thought it was esp32-solo that I have heard of.

Setting up to do projects on an ESP32-CAM board

I have a number of ESP32-CAM boards that I think have ESP32-SOLO-1 modules (maybe not). The metal cap says ESP32-S, not ESP32-SOLO-1 as I saw on digikey.com photos. I'm trying to use them with ESP-IDF and ESP-CAMERA component: https://www.amazon.com/Aideepen-ESP32-CAM-Bluetooth-ESP32-CAM-MB-Arduino/...

ESP32CAM board "AI Thinker" available pins

I've just started tinkering with this AI Thinker esp32cam board: https://i0.wp.com/randomnerdtutorials.com/wp-content/uploads/2020/03/ESP32-CAM-pinout-new.png?quality=100&strip=all&ssl=1 I looked up the pins. It looks like the whole left side is the SD card pins. I plan to use the SD card slot. Even...

Re: Is esp_camera part of ESP-IDF or just part of ESP_Arduino?

Excellent! Thanks for the help! So I guess this is not part of ESP-IDF but still under Espressif. I feel much better knowing espressif owns this repo. They're not industry giant but has put in some impressive efforts on software support. I'm going to look at whether I can rotate images captured by f...
