The XIAO also has 11 digital I/O pins, sharing the same pins as the analog inputs. Note that the maximum voltage you can apply to these inputs is 3.3-volts. The Seeeduino XIAO has 11 analog inputs, each connected to a 12-bit A/D converter. You can also power the XIAO by providing your own 3.3-volt power supply and connecting it to pin 11 вЂ“ in this case the 5-volt pin is non-functional.

If you apply 5-volts to pin 13 you can use pin 11 as a 3.3-volt output. If you power the XIAO with the USB-C connection then you can use the power pins as outputs, delivering 5-volts on pin 13 and 3.3-volts on pin 11. The power pins can be used as inputs or outputs, as they are attached across the DC-DC converter. This is an ideal method of powering the XIAO with a small LiPo battery.

You can use the VCC and GND connections underneath the XIAO and apply 3.7 to 5-volts.

You can apply 5-volts to pin 13, this will be reduced to 3.3-volts by the internal DC-DC converter.

The USB-C connector powers the XIAO from the attached computer.

There are actually a few different ways of powering the Seeeduino XIAO: The ATSAMD21G18 processor is a 3.3-volt device, however, the XIAO has an onboard XC6206P3232MR DC-DC Power Converter to allow the board to be powered by 5-volts as well. Most of the pins on the Seeeduino XIAO serve multiple functions, so it is easier to examine them by dividing them into functional groups. This allows the pin numbers to correspond to the port numbers for the digital I/O and analog input connections. Unlike most modules, the pins on the XIAO are numbered starting at 0 instead of 1, so the pins range from 0 to 13. The Seeeduino XIAO is a tiny module with 14 output pins, as well as a few other surface connections. Adafruit and Sparkfun also make boards using the SAMD21 microcontroller. Seeedstudio also makes the Seeeduino Cortex-M0+ and Seeeduino Lotus Cortex-M0+, both of which support Grove connectors. This processor is used in a number of other microcontroller boards, including the Arduino Zero, Arduino MKRZero and Arduino MKR 1000 boards.

6 serial communication modules (SERCOM) configurable as UART/USART, SPI or I2C.

This tiny wonder has been around since 2012 and it has the following specifications: The heart of the tiny Seeeduino XIAO is the Atmel ATSAMD21 Cortex M0+ 32-bit microcontroller from Microchip. So letвЂ™s take a look at that before we hook up our XIAO. To understand the Seeeduino XIAO you really need to understand the microcontroller chip that powers it, the SAMD21. The only connector on the board is a USB-C jack. The boards are packaged with some male header pins which you can solder in if you wish to use them, or you can just wire to the pins directly. The XIAO is available individually or in 3-packs, and itвЂ™s a quality build. In performance, this thing is light years ahead of the ATtiny85. In fact, itвЂ™s probably about the smallest Arduino-compatible board youвЂ™ve ever seen, with the exception perhaps of a few ATtiny85-based offerings. The Seeeduino XIAO is the latest entry (as of this writing) to this group of boards, and itвЂ™s also the smallest. Many of them include вЂњGroveвЂќ connectors, an interface standard used by Seeedstudio and some other manufacturers to simplify interfacing microcontrollers with external sensors and displays. The Seeeduino line of microcontrollers from Seeedstudio are Arduino-compatible boards, kits, and peripherals.

Incidentally, if you are wondering about the origins of the word XIAO, it is a type of Chinese flute that has been around for centuries.

Called the Seeeduino XIAO (pronounced вЂњsh-owвЂќ) it is a 32-bit Arduino-compatible module that can be used to update and improve your Arduino designs. The board we are looking at today is a very tiny and very inexpensive offering from Seeedstudio. And there are other selections as well, Arduino themselves have a range of more powerful microcontroller boards based upon 32-bit processors instead of the old 8-bit designs like the Uno. We have already done that with the ESP32 boards, they are much more powerful than the ATMEGA328-based Arduino boards and have a wealth of additional features. So for more advanced projects or better-performing versions of existing designs, we can look at some other, more modern microcontroller boards.

And it has limitations (such as speed or analog input resolution) that make it a poor choice for some designs. But for all of its advantages, the Arduino Uno is a pretty old piece of technology, dating back to around 2005.
