I love this little camera. It's been very fun to tinker around with. It was very easy using the Arduino IDE to upload a quick example and get going. I can confirm that you need to hold the boot button down before you connect USB to CPU before attempting to upload a sketch. At least I needed to. Also, check to make sure your type-c cable is good. Some type-c cables won't work when uploading sketches. I ran into this problem using a shoddy cable. Once I used a proper cable and held the boot button while connecting all was good, and I was able to obtain an IP address to view the camera output. Also, some reviews have mentioned the heat. When connected to a CPU, the device will indeed start to heat up. HOWEVER -- I have connected it to a little solar charger component I had sitting around, using a 3.7V 1200 mAh lipoly battery. There is absolutely zero heat. None whatsoever. I need to say that the camera doesn't pick up all to much in low light. But that's a very fair trade-off for the price and the size. The stream is a little laggy with higher resolutions. Still, I have walked around in my yard with this and have been able to easily stream around 150 feet away from my base without losing connection or having too much lag. I'm very happy with this little guy, I recommend, and will definitely be purchasing more.

The module I receive in June 2026 already had the newer OV3660 camera instead of the obsolete OV2640 which was advertised on Amazon. This can be checked with sensor_t *s = esp_camera_sensor_get(); Serial.printf("PID=0x%04x\n", s->id.PID); If it's 0x3660, you have the newer camera. With jpeg setting 2 and size FRAMESIZE_UXGA, you get a very nice JPEG image, about 300k large. Note: plugged right into a Mac, the camera did not always initialize, it only worked when plugged into a power USB-C hub (I used a 4-port Belkin).

Nice little camera. Fairly easy to program. Very very tiny. This one is a bit more money but it has the built in programming module to make flashing the firmware easier. It provides it's own web interface on your local network. Picture quality... well it's not 8K but decent enough. You need a 5V power supply but any phone charger or 5V battery will work fine. Don't buy it if you don't know what you are doing but it's good value if you are into tinkering.

Purchased 3. 1 would not boot. The other two compiled and ran the cam server. The camera is VERY low quality with maybe 25-50 dead green pixels that require software correction to hide. The first images look good but the CCD starts to warm up and loses a great deal of sensitivity. The images after being on for 30 seconds become so washed out that they lose all color and clarity. Even low resolution setting doesn’t help. After 5 mins board is too hot to touch and the picture is almost greyed out completely. It is impressive how small it is I just wished they worked better. Perhaps a different camera will give better results. I use the ESP32 seeed mcus for other IOT projects (thermometers and hygrometers) and they work fantastic for that purpose.

The Seeed Studio XIAO ESP32 S3 Sense is an excellent compact board packed with features. Built-in Wi-Fi and BLE 5.0 make connectivity seamless, and the OV2640 camera plus digital microphone open up lots of possibilities for vision and audio-based projects. Having both 8MB PSRAM and 8MB Flash is a huge advantage for running more complex applications, including embedded ML. I really like the small form factor—it’s easy to integrate into IoT projects—and the fact that it supports battery charging makes it super practical for portable solutions. The interfaces are rich and well-documented, so getting started was smooth. Overall, this is a very capable and affordable development board for IoT, AI, and edge ML experiments. Highly recommended for makers, hobbyists, and developers!

It works ok for streaming video with the example code from Seeed Studio, but it heats up a LOT. The box came with two heatsinks, but there's not really a good place to mount them because the camera board stacks on top of the ESP32. After ~2 mins of using it, it was too hot to hold and starting to smell like a toasty PCB. I was hoping to use this for a project, but it's not going to be workable if it's hot enough to burn me.

I used a few of these to Jerry-rig tracking cameras to my VR headset. They all worked well, but I did run into a few minor issues: - The ribbon cable can be really hard to seat in this type of connector. The USB-C port sort of gets in the way, forcing you to insert it at an angle. - The board refused to let me flash firmware unless I kept the tiny, hard-to-press BOOT button held while plugging it in. This was pretty hard to do without letting go of the button. - These get EXTREMELY hot. The guide I was following recommends you all mount them close together, but for peace of mind I ended up having to wire a small fan to keep them cool. I'm only taking off one star because most issues boil down to limitations of the technology and/or user error.

This was trivial to set up and stream video from it to a webpage on my home network. It’s tiny, and the only challenge was figuring out the antenna connection, but their wiki was good guidance. It’s a nice piece of kit. Programming through the Arduino ide was simple.

小さくて、カメラ、マイク、WiFi、SDカードが使えるとか、自分としては楽しめてる

For all the RAV out there saying that this is the product to buy I can’t even get 1080 P at 30 frames a second on this device, useless. It’s just a toy, I guess

Einfach ein cooles Ding Wird relativ heiß ist aber ganz normal

Hi, On top of the non so cheap price (€39,00) I get an invoice for custom taxes for €28.85 making a total of €67,85 ! If I had know this has to come from China, I never would have bought it !

الكاميرا سيئة جدًا جدًا. يلزمك وجود إضاءة عالية جدا من أجل الحصول على تصوير جيد، أما في الظلام فهي بلا قيمة تمامًا. وهناك عيب آخر وهي السخونة.. البورد والكاميرا يسخنان بسرعة شديدة في أقل من 3 دقائق لدرجة أنك لاتستطيع حتى إمساكها. الشيء الإيجابي الوحيد هو أنها صغيرة جدا حتى بعد تركيب كل القطع
