Powerful Little Board for IoT and AI Projects!
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!

Amazing value and dead simple to use
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.

they are really small and battery life is outstanding. i would certainly rebuy these.
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.

Capable chip. Small size. C6 NOT WLED compatible
This review is for the Esp32-c6. It’s a good chip and I’ve had success with it. I bought due to small size, WiFi, Bluetooth and optional external antenna. Accidentally thought wled would work. But it is NOT compatible with WLED. So I had to program it myself. While a fun leaning experience I didn’t plan on it. Also been having problems with PlatformIO and Espressiv compatibility. I’ll find a library that wants platformio v-latest but only works with Espressiv v3. It’s been a nightmare. Espressiv is nice just different and its own world. The ws2812b led library required old expressive so I had to look up old Bluetooth coding style - and docs are always about current versions A good chip with vendor support. But not well supported in the open source world. Limiting and increased blood pressure. 😇

Powerful little board
I grabbed a standard ESP32C6 and unlike the module with the camera, it doesn't have any heat issues. It works beautifully, is very affordable, and includes a built-in ceramic antenna so you don't need to attach an external. It's fast, responsive, and powerful. Very easy to use. It connects to my wifi with no issue. Admittedly, I haven't tried Bluetooth, but I'd imagine it works just as well.

Surprisingly feature rich and powerful for the price
Lots of code support online for getting this up and running. Easily had it serving a website on my local network for remote control via ngrok, plus powered some pretty hefty motors with only USB power and no issues. Impressive for the price and size.

Great Buy
Works well for small projects like wearables

Device gets very hot; GPIOs & BLE don't work
I bought this development board to incorporate into a wireless project utilizing both BLE and ESP-NOW. After unpacking the board and attaching the antenna, I connected it to my computer and attempted to upload my BLE sketch that I tested on another ESP32C3 DevBoard. When this failed, I uploaded the example BLE sketch for the Xiao. The sketch successfully uploaded but the board became almost too hot to touch while running the program. Furthermore, it did not show up when I scanned for it with my phone using the nRF Connect app. I then tried debugging. The example sketch was supposed to change the device name when D0 was pulled to ground by a button press. I attempted this to no avail. First I checked the Serial connection by uploading a Hello World sketch. That ran successfully. I then modified that code to print when the button pin was pulled to ground. It didn’t work. Connecting my multimeter to the button pin was floating at ~100mV even though INPUT_PULLUP was declared in the pinMode(). I repeated this for pins 1-3 and it failed everytime. That is where I gave up and tried to replace it. All Amazon offered was a return. I hope to try it again in the future. SUMMARY: The Bluetooth didn’t work, even with code known to work on another ESP32C3. The device runs very hot. The GPIOs do not function as inputs and remain floating even when INPUT_PULLUP is called. I might have received a rare defective board. Now at ~$17 I’m not willing to pay double the price I originally paid to find out.

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。
