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

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.

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.

The media could not be loaded. Great little device. Bought it pre-soldered for my first ever project involving anything electronic and it didn't disappoint. Lots of documentation available online. I didn't make use of most of the features, but used it to run a stepper motor driver, read a thermistor that is attached to the motor as a fail safe incase the cooling fan fails, and to read a rotary encoder to adjust the speed and direction of the motor. P.S: the images show the incomplete project. I need to make a housing, but the electronics work amazingly!Great little device and incredibly tiny!!

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.

This is one of those rare finds that ticks every box!”

I programmed it as a wifi access point and web server to deliver web pages to a web browser running on a tablet, cell phone, laptop or pc. I stored .png images on the esp32c6 using LittleFS that the web page was able to include in its display as an html body background image as well as html img images. I used Arduino IDE version 2.3.6 with C++. I have it defined as an XIAO_ESP32C6 board definition in the Arduino IDE. To get the onboard led to blink on and off, in void setup(), I specified pinMode(LED_BUILTIN,OUTPUT); and later in void loop() I was able to toggle it on and off in void loop() using digitalWrite(LED_BUILTIN,LOW); and digitalWrite(LED_BUILTIN,HIGH); I was also able to use a BME280 temperature sensor to the XIAO_ESP32C6 using pins D4 to SDA and D5 to SCL as well as supplying VIN and GND to the BME280. I will definitely be purchasing more of these XIAO_ESP32C6 microcontrollers.
