Description of Seeed Studio Seeeduino XIAO SAMD21 Cortex M0+ Board: 100% Arduino IDE Compatibility, Breadboard Mountable, USB Type-C (3pcs)

[Flexible Compatibility] Seeeduino XIAO development board is Fully compatible with the Arduino IDE ,you can easily develop some Micro projects with the help of the large and comprehensive Arduino library. As it has a 2.54mm pin pitch, it is a replacement for Arduino microcontroller that can be used even when inserted into a breadboard. [Ultra Small] Seeeduino XIAO board is as small as your thumb (about 20x17.5mm) and can be used to make small devices such as wearable devices. The Seeeduino XIAO Development Board is the smallest board Compatible with Arduino in the Seeeduino series. [Multiple development interfaces] 11 digital/analog pins, 10 PWM Pins, 1 DAC output, 1 SWD Bonding pad interface, 1 I2C interface, 1 UART interface, 1 SPI interface. Attention:All the I/O pins are 3.3V, please do not input more than 3.3V, otherwise, the CPU may be damaged. [USB Type C Support] Seeeduino XIAO supports the USB Type-C interface which can supply power and download code. Type-C is more robust than Micro USB.And there are power pads at the back of the XIAO which support battery and make it designed for wearable devices to become realistic.

Simple, compact, and solder-free

It's nice to have a slotted component option that allows for quick replacement, prototyping, or reconfiguration without soldering. Order yourself a Seeeduino with the pins installed so you can use it without soldering.

Pros
  • This is amazing
Cons
  • Miscellaneous Miscellaneous

Fully compatible with Arduino IDE

Very small and perfect for development. The boards come with clear instructions on how to download the board's libraries and packages. The USB-C connector feels nice and makes the board easy to use with my usual cables.

Pros
  • Confident
Cons
  • Not bad

Loader issues

These things seem good, but I have to reset them every time I upload the code. This is a known issue that doesn't seem to have a fix. It's best to solder the button to the tiny reset pads with 2-4" wires. Use this device for development purposes only. I used the Adafruit Trinket M0 instead.

Pros
  • High marks for support and durability from testers
Cons
  • Vulgarity

USB C and small is best

These little guys are great. I use them to measure the temperature and humidity in my apartment and using the rf module to send that data to the esp32 for internet connection works great. It was quite difficult to set up and use on the "Seeeduino XIAO" board, which differs from the manual in my opinion. But I will buy more for portable devices along with USB-C battery.

Pros
  • Handsfree
Cons
  • Update Available

Small but powerful with some issues

Xiao have a cool design, they're light, small, use a USB-C connector, are powerful and, perhaps most importantly, very cheap. manually reset before writing and for some reason I couldn't use the I2C interface, but maybe I'm doing something wrong. I only play with them for a few hours. I had high expectations and have not been disappointed so far.

Pros
  • Durable finish
Cons
  • No automatic

DO NOT recommend using on MAC

I have an Arduino IDE for Mac. I have downloaded all necessary files for these boards. We managed to chat and upload the sketch to the first board. It started and worked fine. I tried uploading another sketch to the same board and the PORT was gone. No more contact could be made with him. Tried the second board. I was able to upload the sketch to the board with no problems. I tried uploading another sketch to this board and the port disappeared just like the first board. Tried the third board…

Pros
  • Decent performance
Cons
  • Almost never

My favorite little non-ESP.

To be honest, I just don't see myself being able to use other microcontrollers without Wi-Fi for my projects. I had to do some library shopping to get it working, but I think most of it was just inexperience on my part. The project pictured above is an MQ four sensor gas analyzer with an OLED display powered by a 5V USB power supply C. 5V is used to power the sensors and a small fan, of air circulates while the MPU runs at 3.3 VI. Bought a second set of three, an expansion board and some Grove…

Pros
  • Robust construction
Cons
  • Secret
