XIAO ESP32C3 3PCS Pack - RISC-V Tiny MCU Board with Wi-Fi and Bluetooth5.0, Battery Charge Supported, Power Efficiency and Rich Interface

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!

very practical and small for the price and functionality. The connectors are a little fragile so definitely be careful with that! It even comes with its own battery charging IC which is super cool for the size!!

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.

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. 😇

I'm using these for Home Assistant and room presense (ESPresense) and so far they work well. I had another brand that had a built-in WiFi antenna (red chip-like thing on the board) and it seemed to be ok, but the WiFi died on it a couple of weeks later. These have a plug in (fragile plug and thin little antenna panel), which I don't really prefer, but they seem to work well so far. I just need to get used to how to adjust ESPresense and the Bluetooth strength of these boards. I wish there was a little plastic box to put these into that would make them pleasing to the eye, but I'll figure that out. Flashing them was a breeze and for a 3 pack the price was right. I did solder the pin headers on the board and that went pretty well. For the price, the quality seems good.

This was trivial to set up and stream video from it to a webpage on my home network. It’s tiny, and the only challenge was figuring out the antenna connection, but their wiki was good guidance. It’s a nice piece of kit. Programming through the Arduino ide was simple.

Nice little camera. Fairly easy to program. Very very tiny. This one is a bit more money but it has the built in programming module to make flashing the firmware easier. It provides it's own web interface on your local network. Picture quality... well it's not 8K but decent enough. You need a 5V power supply but any phone charger or 5V battery will work fine. Don't buy it if you don't know what you are doing but it's good value if you are into tinkering.

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.

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

Ein S3 halt - mit wenigen GPIOs nach außen geführt - hakelt manchmal bei der USB Verbindung, muss man den S3 dann 126372 mal neustarten, bis es geht - aber sonst klein und funktional.
