Thinking of the next big camera project? Tired of selecting between countless camera devkits with questionable designs and unknown origins? Want to hack something that "just works"?

I have a solution for you! The multi-purpose AI camera combines all the features you'll ever need for your camera to be successful:

• ESP32-S3 chip compatible with TensorFlow Lite, enabling AI right in the device.
• OV2640 camera sensor delivering 15 fps @ 2MP.
• Ultra-low power design: programmable external RTC controls the entire power distribution, allowing the device to consume microamps during sleep.
• Motion detection with wake-up support.
• Nightvision mode with software-controlled IR filter to improve pictures during daytime.
• 8 IR LEDs to illuminate the scene.
• Ambient light sensor to intelligently select between day and night-time modes.
• Convenient 70mm x 70mm form factor.
• JST-PH battery connector.

  • First Revision Arrived!

    JLCPCB did a great job, as always. 

    Quite a list of things to test, but USB, JTAG and CDC seem to be working fine:

    [27615.070318] cdc_acm 5-3.2:1.0: ttyACM0: USB ACM device
[27615.451032] usb 5-3.2: USB disconnect, device number 122
[27615.803839] usb 5-3.2: new full-speed USB device number 123 using xhci_hcd
[27617.497138] usb 5-3.2: new full-speed USB device number 124 using xhci_hcd
[27617.726271] usb 5-3.2: New USB device found, idVendor=303a, idProduct=1001, bcdDevice= 1.01
[27617.726276] usb 5-3.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[27617.726278] usb 5-3.2: Product: USB JTAG/serial debug unit
[27617.726280] usb 5-3.2: Manufacturer: Espressif
[27617.726281] usb 5-3.2: SerialNumber: F4:12:FA:E8:62:6C

    By the way, did you know that ESP32S3 and IDF have built-in USB peripheral support with JTAG and a console? So you no longer need to keep auto-flashing circuits on your ESP32 boards. More information here:

    Good start, nevertheless. Stay tuned!

    At this point, all project files are submitted to jclpcb and I hope to receive our board within a few weeks!

    Meantime, there is a lot of work on the software side of things.

Re-posing here from the chat:

The BOM optimization is still in progress, so I would like to refrain from posting the final figure :)

I'll let you know when I finish testing and the new revision.

  Are you sure? yes | no
