Seeed Studio XIAO ESP32 S3 Sense - 2.4GHz Wi-Fi, BLE 5.0, OV2640 Camera Sensor, Digital Microphone, 8MB PSRAM, 8MB Flash, Battery Charge Supported, Rich Interface, IoT, Embedded ML …

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!

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.

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.

Worked extremely well for me. It does run a little hot but is a fun device to fiddle with and will, hopefully, be the basis for a few projects of mine.

Every XIAO I've purchased from Seeed Studio has been perfect. This company makes excellent products and this has been no exception so far. yes, the XIAO may not have all the GPIO exposed but that is not the point. They are meant to be very small and excel at their purpose. They have just enough pins exposed and the quality is better than just about any other brand out there.

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.

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.

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

Seeed studio esp32c6 is the best! no issues at all. runs 1st time and every time. No power issue, No code compatibility issue, No bluetooth issue! Ok, 1 limitation though, can't define more than 4 characteristics per service. But got around it by declaring more Services anyway so just a minor issue. Overall performance, 9/10.

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
