ESP32-S3: Support OV3660 Camera Sensor in espcamera

[bikeNomad]

I just bought a couple of the xiao esp32-s3 sense boards, and have found that Circuitpython does not support the new (OV3660?) camera sensor. The example code on the Seeed Wiki doesn’t work.

My test code just tries to capture a single image:

import os
import espcamera
import board
import sdcardio
import storage
import time
import busio
import errno

sd = None
try:
    sd = sdcardio.SDCard(board.SPI(), board.SDCS)
    vfs = storage.VfsFat(sd)
    storage.mount(vfs, '/sd')
    print(os.listdir('/sd'))
except Exception as e:
    print(f"SD card mount failed: {e}")

# OV5640 Camera can do 1600x1200 (UXGA)
FRAME_SIZE = espcamera.FrameSize.VGA
# FRAME_SIZE = espcamera.FrameSize.UXGA

i2c = busio.I2C(board.CAM_SCL, board.CAM_SDA)

cam = espcamera.Camera(
    data_pins=board.CAM_DATA,
    external_clock_pin=board.CAM_XCLK,
    pixel_clock_pin=board.CAM_PCLK,
    vsync_pin=board.CAM_VSYNC,
    href_pin=board.CAM_HREF,
    pixel_format=espcamera.PixelFormat.JPEG,
    frame_size=FRAME_SIZE,
    i2c=i2c,
    external_clock_frequency=20_000_000,
    grab_mode=espcamera.GrabMode.WHEN_EMPTY,
    framebuffer_count=2,
    jpeg_quality=10)

cam.vflip = True

jpeg = cam.take(1)
if jpeg is not None:
    print(f"Captured JPEG of length {len(jpeg)}")
    if sd is not None:
        with open('/sd/test.jpg', 'wb') as f:
            f.write(jpeg)
        print("Stored JPEG on SD")
        print(os.listdir('/sd'))
        storage.umount('/sd')

del cam

When I run the above code, I get this response:

Adafruit CircuitPython 10.0.3 on 2025-10-17; Seeed Xiao ESP32-S3 Sense with ESP32S3

Auto-reload is on. Simply save files over USB to run them or enter REPL to disable.

Code done running.

I've also tried the latest build.

Would it be possible to support this sensor?

Thanks!

Please test #10719. It was digging into how to enable it and it was simple enough to just do it.
