Seeed Studio XIAO ESP32C3 - Tiny MCU Board with Wi-Fi and BLE for IoT Controlling Scenarios. Microcontroller with Battery Charge, Power Efficient, and Rich Interface for Tiny Machine Learning. …

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.

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!

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

Thought I'd give these a try for a Low Power Battery Operated WiFi Project. They have 11 Inputs, 4 can be assigned for Analog Inputs, I2C Communications (as well as other Comm options) and Digital I/O.The Analog Inputs caught my attention as the Low Power Battery Operated System I was designing required at least 2 Analog Inputs, one for the Sensor and the other for monitoring Battery Voltage. (The WEMOS R1 Di Mini has only one Analog Input).The Breadboard design worked very well, however I was able to locate I2C Communication Sensors that eliminated the need for Analog Inputs. Therefore, these units have been placed in my inventory awaiting a suitable application.Pros:1-Appear to be well built2-Small Form factor3-Low Power Settings available4-Built-in Li-Ion 18650 Battery Charger with Protection Circuit (I have not tested as yet)5-External Antenna allows easy placement in enclosure6-Fast Processor Clock7- Built-in WiFi & Bluetooth8-Check "seeed studio" ESP32C3 Datasheet for full detailsCons:1-The external WiFi Antenna could also be considered a negative, depending upon application.

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!
