These little ESP32C3s are an incredibly good package for the price. Very small, with a nice set of pin outs, a reasonably powerful SoC, and support for any number of external wifi antennas have made these my board of choice for a number of ESPHome powered automations, from weather stations to chicken coop monitoring equipment.It would be nice for the Amazon ones to offer a variant with headers soldered on, but its not really a terribly big deal to solder your own on.

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 programmed it as a wifi access point and web server to deliver web pages to a web browser running on a tablet, cell phone, laptop or pc. I stored .png images on the esp32c6 using LittleFS that the web page was able to include in its display as an html body background image as well as html img images. I used Arduino IDE version 2.3.6 with C++. I have it defined as an XIAO_ESP32C6 board definition in the Arduino IDE. To get the onboard led to blink on and off, in void setup(), I specified pinMode(LED_BUILTIN,OUTPUT); and later in void loop() I was able to toggle it on and off in void loop() using digitalWrite(LED_BUILTIN,HIGH); and digitalWrite(LED_BUILTIN,LOW);

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.
