seeed studioXIAO ESP32C3 -RISC-V Tiny MCU with Wi-Fi/BLE5.0, Battery Charging, Ultra-Low Power, Rich Interfaces. Engineered for LoT Control & Edge TinyML

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.

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.

Really cool ESP 32. It can even run AI on it.

Really impressed with this thing. There are so many things you can do with it (sensors, write data to micro-sd, take photos, streaming video with a webserver, get it on Meshtastic with another peripheral, etc.) in either C (Arduino) or Python. So tiny, so much, so neat! (and hot!).

The microcontroller works great and comes with the antenna! The only thing I had trouble with was Pin D9 would only work as an output for me. I read pin D9 is linked to the boot button. Maybe there is a way to configure that, but I haven't figured it out. I am using mine for a Bluetooth keypad, and I do have enough GPIO, but I had to resolder to another one and change the code for my project to work.
