XIAO ESP32S3 3PCS Pack- 2.4GHz WiFi, BLE 5.0, 8MB PSRAM, 8MB Flash, Dual-core, Battery Charge Supported, Power Efficiency and Rich Interface, Ideal for Smart Homes, IoT, Wearable Devices, Robotics.

Great little boards and incredible value for the money. Perfect for ESPHome. Dead bug it or solder onto a protoboard with the castellated pads. I didn’t realize it had a built-in battery circuit, have not messed around with that but I intend to try it out sometime. No temp wire makes me nervous though. Can’t get easier to program and flash than ESPHome builder- Claude code can just spit out the yaml you need and you’re up and running in seconds. Comes with little WiFi antennas but I actually found the reception isn’t too bad without it.

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!

These were something of a chore to flash, but once you figure it out, they function great. they are really small and battery life is outstanding. i would certainly rebuy these.

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 built 2-Small Form factor 3-Low Power Settings available 4-Built-in Li-Ion 18650 Battery Charger with Protection Circuit (I have not tested as yet) 5-External Antenna allows easy placement in enclosure 6-Fast Processor Clock 7- Built-in WiFi & Bluetooth 8-Check "seeed studio" ESP32C3 Datasheet for full details Cons: 1-The external WiFi Antenna could also be considered a negative, depending upon application.

Great little board! An on board antenna would have made it smaller and stand alone chip! :)

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?

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!

Cute little board. Expect to write C and not C++ in Arduino to get full functionality. Arduino IDE works but it's sketchy

Produit conforme et livraison rapide

It's a great little board. Now even easier to program using ChatGPT.

Is a nice small crazy computer

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

製品に問題はなかった。不満なし。 購入前から想定してた通りカメラとWi-Fiを同時に使うと爆熱だね。 ひとつ気になったことがあってov2640でなくov3660がついてた。廃盤になってるらしいから在庫分処分できたのかな。 ページ内容と違うがむしろありがたいので結果オーライ。
