I honestly just do not see myself using any other microcontroller for my non-wifi projects.
I had to do some shopping for libraries to use to get everything working but I think most of that was just inexperience on my part.
The project pictured above is a four MQ sensor gas sniffer with an OLED display powered by a 5V USB C power brick. The 5V is used to power the sensors and a small fan that pulls air through while the MPU operates on 3.3V.
I bought a second set of three of these, the expansion board, and a handful of grove connector cables. I honestly don't know if I will use the expansion board since I have had little trouble experimenting with these with a few I2C devices. The expansion board has a debug interface that might make it useful one day for me.
If one does not need the wifi or BLE of an ESP32/8266 then I would recommend this microcontroller. I used YouTube for all of my initial research and the manufacturer's web site and forums afterward. I develop with PlatformIO, but was also able to program using the Arduino IDE.

Tips:
Seeeduino XIAO board has been becoming more and more popular in our community since it was released! many fans of Seeeduino XIAO board have been asking whether we will have a Grove Shield for it, the much-anticipated Grove Shield for Seeeduino XIAO is released.
Grove Shield for Seeeduino XIAO is a plug-and-play Grove extension board for Seeeduino XIAO board. With the on-board battery management chip and battery bonding pad, you could easily power your Seeeduino XIAO with lithium battery and recharge it. And On-board Power Switch and Charging Status Indicator Light.

|---|---|---|
[Powerful CPU]Seeeduino XIAO development board carries ARM Cortex-M0 + 32bit 48MHz microcontroller (SAMD21G18) and low power consumption. The clock frequency is 48MHz, which is three times that of Arduino Uno and Arduino Nano. In addition, this Arduino IDE compatible board is equipped with 256KB flash memory and 32KB SRAM. |
[Flexible Compatibility]The Seeeduino XIAO development board is Fully compatible with the Arduino IDE ,you can easily develop some small projects with the help of the large and comprehensive Arduino library. As it has a 2.54mm pin pitch, it is an Arduino microcontroller that can be used even when inserted into a breadboard. |
[Ultra Small]This Arduino IDE compatible 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 Arduino compatible board in the Seeeduino series. |
Seeeduino XIAO Hardware Pinout
Seeeduino XIAO main features
[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.
[14 GPIO PINs]
The Seeeduino XIAO microcontroller has 14 GPIO PINs, 11 of which can be used as digital input/output or analog input.
Some of these pins have multiple functions. For example, pins A1/ D1 to A10/D10 can be used for PWM output,
and pins A0/D0 can be used as DAC output. In addition, there are pins that can be used as interfaces such as I2C, UART, and SPI.
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 interface]
The Seeeduino XIAO development board supplies power from the USB Type-C interface and writes sketches to the microcomputer board. Type-C is a more robust interface than Micro USB.
There is also a power pad on the bottom of the Seeeduino XIAO that allows you to connect a battery.
Seeeduino XIAO has not only power LED but also user LED, so you can enjoy Blinky immediately. It also has a 32.768kHz crystal for the built-in RTC.

Small and easy to use----This is the smallest Arduino compatible board among all the development boards I have used,
Surprisingly, although this development board is small, it has a large capacity and rich interfaces. Also the size provides enough to be used in a complete PCB project.
