*Insanely Tiny* Camera Dev Module (with ESP32-S3) 

Hey, I am interested in getting a usb webcam uvc to work with my M5stack ESP-32 Core S3 (Built in display) What firmware or code is need for USB WEBCAM UVC ? it has a built in usb-c otg port to work with usb otg devices

@@BushMasterThermal Please take a look at my UVC project. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lAVtS-HdMpo.html Also, check the code here. github.com/espressif/esp-iot-solution/tree/master/examples/usb/host/usb_camera_lcd_display

Is it a problem to attach a SD-Cardmodule?

@@viktorhugo8252 It already has the SD card slot. Cannot use this one???

@@ThatProject , I don’t see this. I think this need 4 free GPIO?

Will you share your project anywhere on the Internet? Keen to know more.

A detachable antenna is included. Normal WiFi communication is only possible by attaching this antenna.

I'll try it sooner or later.

It uses OPI (Octal) PSRAM.

@@ThatProject I've got a feeling that the webcamserver example code and it's libraries could be optimized for use with the s3 module. I've compared some code between the original esp32s and the s3, and in cases where RAM or flash are a bottleneck on the s, the s3 feels 2x the speed (which makes sense because the s3 has octal flash and ram compared to quad on the original s used in the AI-thinker board). If the s3 doesn't run webcamserver much faster than the AI-thinker esp-cam, then perhaps the code could be optimized to take better advantage of the faster RAM. Another bottleneck could be the ov2640. The original esp-cam runs faster with the ov2640 than with the 5640, but the s3 might be fast enough where the 2640 itself could be the bottleneck, and it may actually run faster with the 5640 or another module. So many variables to test...

@@JesseHughson Like you said, I think we can test a lot of things. It seems that the S3-based camera module will show better performance in many ways. Let me test it with OV5640.

I tried searching with ESP32-T4 but couldn't find the camera module. Do you have a link to a product?

@@ThatProject Sorry, Esp32-P4

@@spaikersnc is the Esp32-P4 already released? what cameras are you referring to? would love to see a test with Esp32-P4 too... would also love to see a project with a Wi-Fi controlled Paper Airplan using Esp32-P4 or etc.

I know what you're talking about. It is quite cumbersome to change to upload mode by connecting GND and IO0 on ESP32CAM. On Xiao Cam, press the small button during restart to enter upload mode. It's not bad, but it's still annoying.

Unfortunately, nothing came bundled with the camera. It seems that the only way is to attach something like a heatsink behind the sensor.

As far as I know, the performance is not much different since they use the same OV2640. It just has the advantages of a larger PSRAM, Built-in UART-Serial, and a smaller form factor.

You don't have to use my app. For the test, you can try it with VLC Player. If it doesn't work with VLC Player, then your ESP32-CAM doesn't work properly.

@@ThatProject I don't mean this video, but a video that you used an App that can help record and save Esp32 cam output

@@abdulrahmanbabatunde5427 haha. I know you're talking about my ESP32-CAM Viewer App. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-S6Y_n-Axtmk.html I meant you have to check your ESP32-CAM first with the VLC player instead of my ESP32-CAM Viewer app. It'll let you know which one has the issue.

@@ThatProject I tried the VLC player but didn't display the camera but it is working perfectly on Chrome.

In short, you need to have 8MB PSRAM for getting a frame buffer from the image sensor. If the old module does what you want, then I think it's okay to use it.

I'm using this on my RC car. It gets hot, but there was no problem using it. What issues were there?

You can get individual image and voice data, but it can be difficult depending on how you use it. If you are configuring a general CCTV environment, it may be wise to use IP cameras.

@@linciyuan598 I’m using it fine. Are you sure you have connected the external antenna? Or there is a possibility that the connection to your WiFi device is not good.

I have only experience with Arduino H7 Vision Shield which has a monochrome camera. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-c0kyl7OURRs.htmlsi=m8jXKTfFNlcmr7n0 It has this camera module(www.himax.com.tw/products/cmos-image-sensor/always-on-vision-sensors/hm01b0/). Are you trying to do some vision projects? That's why you need to have a monochrome camera?

@@ThatProject It's more of a personal preference thing. Lots of examples shot a lot of color noise and I think a monochrome sensor would be more fun to use for myself. Some appear to be global shutter too

Additionally, my unit gets extremely hot. I have only powered it on to upload the sample 'take photos' sketch and I can smell the PCB and it's very hot to the touch. If that's expected, I will be returning this unfortunately

@@AdmiralSym I could feel a slight smell, but I don't think it was that hot. If you have any problems just return it.

We need to think a few things about FPS. It is possible to acquire images at 30 fps in VGA resolution with ESP32 from OV2640. The problem is that we use WiFi to transmit these images elsewhere. FPS drops because of this. Alternatively, saving the image to an SD card can sustain a higher FPS.

You can drive the camera using the CameraWebServer in the ESP32 Arduino Basic Library. This is how the camera becomes a server, so you can access 2 cameras at the same time from one client (PC Web browser). Alternatively, the camera can become a client and transmit to a single server. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rTY2Ibk-gco.html

@@ThatProject Thank you for responding. The video you shared is very helpful, but I'm hoping to achieve better power efficiency by running two (or three) cameras on a single chip or even a different chip. Is there a chance that I could locate the camera driver's library to implement it on another platform? Thank you once again for providing such a valuable channel.

@@JustHangOutWithMe Since the ESP32 can only use one DVP image sensor, multiple camera modules cannot be used. If video streaming is not required, multiple SPI cameras such as Arducam Mega(ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-5ygPx5FUH1Y.html) can be attached to the ESP32. It can be operated with very low power as it can only take pictures when needed. This project is also in preparation. I hope to finish soon. If you need video streaming from multiple cameras, you'll have to use an SBC (like a Raspberry Pi board). There is a way to connect multiple USB cameras.

What problem are you having specifically? The basic examples work fine without any problems.

Do you want to transfer the JPEG image frame obtained from ESP32CAM (slave) to ESP32 (master) through i2c? It may vary depending on the frame size, but I think only a few pictures can be transferred per second. Is that what you want?

@@ThatProject Huge thank for replying. I Need the video for a toy car in live movement. But based in your answer it won't be possible for ram limits?

@@svsv9 It seems impossible to connect and view two cameras live. However, in the case of one device, wouldn't it be possible to transmit data via WiFi? ESP32 operates as a server, and ESP32CAM connects as a client and starts streaming.

@@ThatProject Thank you for light me, I should have read a lot before going to ask you my friend, and that's I am going to to do. Asking you is like going to w@r without training. I need two cameras available but only one working and connected at time( let say the front forward of the toy car at the time of movement), if I chance way, one camera will be off and the opposite camera will turn on and so on. Thank you so much I will be studying a lot, What I don't want if order hardware that won't be able to accomplish what my requirements. Thank you again. Have a nice day.

So far I have only transferred data wirelessly. This board doesn't have ethernet, how do you plan to connect it wired (RJ45)?

That's the question I'm working on myself. I was hoping you'd have some ideas. Is this camera considered "MIPI" or "CSI"? or are they the same thing?@@ThatProject

@@salukikev OV2640 and ESP32 (MCU) are connected through the SCCB interface. If you need a MIPI interface, you can find a board that includes the OV2640.

It has MSM261D3526H1CPM. I believe you can get an example source code for using it from their official site.

That's weird. Are you sure you are using an external antenna for your XIAO?

@@ThatProject yes, i have the same antenna that you have in your video and it’s plugged correctly, well i think

@@elden4267 I'm not sure what the issue is. Seems like I need to test again. How did you measure FPS?

@@ThatProject by feeling, like the ai thinker is supper smooth compared to xiao side by side

You can find them under its wiki page. files.seeedstudio.com/wiki/SeeedStudio-XIAO-ESP32S3/res/XIAO_ESP32S3_ExpBoard_v1.0_SCH.pdf

😂

Thanks for the tip. I have to be careful.

@@ThatProject Well as long as this video is up there is no point, milk has been spilled.

Some users have reported that it gets hot. I think we need to do more testing on this part.

It doesn't have any options.

@@ThatProject cant you just manually remove the IR filter? :)

@@Gerald-iz7mv It's just the OV2640. You can forcefully remove the IR filter, but sometimes it can damage the lens.
