3 pack of esp32s3. Decent price. I was happy they included antennas. I soldered my own pins to the board. Soldered a 1000mah battery to the terminal. Each had a soil moisture sensor, temperature sensor, and humidity sensor.I have been using the esp32s3 variant for most of my projects due to the most robust support for micropython. With the power of these with cpu with micropython, it takes 30-60 minutes to prototype out the code. ESP now with micropython is very nice and all my sensors utilize it. Sensors all communicate with one master esp32s3 which communicates with an mqtt server. Xiao esp32s3 devices/sensors -> esp now -> master esp32s3 -> mqtt server -> database/triggers

Amazing little gadget. This has a well-built-out ecosystem for programming. It will take some reading, but if you do much with VS Code you can get this working pretty well. I have one doing WiFi scans and it works quite well.Note: you may have to do some soldering to use it w/o the USB, and to put connectable pins on it. The pins will work with breadboards. But you will not need a special programming device--just your computer.

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.

Well, strap on your boots and listen up, 'cause I gotta share my excitement about the Seeed Studio XIAO ESP32C3. This little gizmo ain't just a dime a dozen – it's a real lifesaver, especially for a busy parent like me. Here's why it's gettin' five stars:Now, why am I so excited about this gizmo, you ask? Well, I'll tell ya – I'm usin' it for a door alarm to keep an eye on my rambunctious 4-year-old son. He's a handful, that one, always tryin' to sneak out and explore the great outdoors. But with this XIAO thingamajig, I'll know the moment he even thinks 'bout openin' them doors. It's peace of mind wrapped up in a tiny package.!Small but Mighty: Don't let its size fool ya, this thing's a powerhouse. With Wi-Fi and BLE packed in tighter than a can of sardines, it's ready to tackle any job.Efficient as a Well-Oiled Machine: When it comes to power, this board's as thrifty as a farmer at the market. It barely sips electricity, like it's takin' a leisurely sip of sweet tea on a lazy summer afternoon. Keeps my door alarm runnin' smooth and steady without guzzlin' down the juice.More Connections Than a Family Reunion: Despite bein' pint-sized, this XIAO fella's got more ports than my granddaddy's fishing boat. Perfect for hookin' up all them sensors and gadgets to keep my little ones safe.Charge Like a Tesla at a Supercharger: Picture this – it charges up faster than a Tesla at a supercharger station! Just plug 'er in and she's ready to roll quicker than a herd of cattle stampedin' down the range.Smart as a Whip: And here's the kicker – it's got tiny machine learnin'! That's right, it's like havin' a little brain in my door alarm. Keeps me in the loop faster than a telegraph wire.Yessir, if you're fixin' to wrangle up some IoT contraptions, this Seeed Studio XIAO ESP32C3 is the real deal. Whether you're a city slicker or a country bumpkin, it'll get the job done and then some. So, grab yourself one of these babies and get to tinkerin' – you won't regret it!

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.

The media could not be loaded. Great little device. Bought it pre-soldered for my first ever project involving anything electronic and it didn't disappoint. Lots of documentation available online. I didn't make use of most of the features, but used it to run a stepper motor driver, read a thermistor that is attached to the motor as a fail safe incase the cooling fan fails, and to read a rotary encoder to adjust the speed and direction of the motor. P.S: the images show the incomplete project. I need to make a housing, but the electronics work amazingly!Great little device and incredibly tiny!!
