Arduino Micro
Up next, we have the Arduino Prototype Expansion Board which is a little larger than the Nano as well as has been likewise designed to fit on a solderless breadboard. Nonetheless, it is powered by the ATmega32U4 which is different from the Nano. In terms of size, it is somewhat bigger than the Arduino Nano at 48mm x 18mm.
Besides the strong CPU, Adjustable Dc Power Supply Module is exceptional in lots of various other functions. In spite of being this small size, it has 14 GPIO PINs, which can be used for 11 analog PINs, 11 electronic PINs, 1 I2C user interface, 1 UART interface, and 1 SPI interface. Some PINs have different features, A1/D1 to A10/D10 Pins have PWM features as well as Pin A0/D0 has a feature of DAC which indicates you can get true analog signals not PWM signals when you specify it as an analog pin, that’s why 14 GPIO PINs can understand a lot more I/O PINs as well as user interfaces.
Contrasted to the Nano, the Micro includes even more peripherals for your project needs. With 20 digital I/O pins, 12 analog inputs, as well as 7 PWM enabled pins. Furthermore, with a native USB, you can use it as a mouse, key-board, etc. conveniently. Nonetheless, the Micro bootloader can only be configured with USB that needs a unique driver. With Linux, just a couple of selective versions have the required chauffeur.
Additionally, unlike the Pro Mini, the Micro does not call for an outside board to upload a sketch simply allow the 32U4 deals with everything! Primarily, if you people recognize the Arduino Leonardo, the Arduino Micro is a shrunk-down version of it as well as the Arduino Nano is a shrunk-down version of the Arduino Uno. The micro is the smallest board of the household of ATmega32U4 Arduino.
Seeeduino XIAO
20mm x 17.5 mm.
Lastly, we have the smallest Arduino of this list! The Seeeduino XIAO is the tiniest Arduino compatible board from SeeedStudio’s Seeduino family members and is just one of the smallest Arduino boards around. Sometimes when boards obtain as well small, they shed its functionalities and also capacities but except this Arduino board! The Seeeduino XIAO is an Arduino microcontroller that is embedded with the SAMD21 integrated circuit with abundant interfaces also permitting it to be capable of being a little Dev. Board as well.The board is also breadboard compatible which is very rare for a tiny board similar to this!
The Seeeduino XIAO sustains the USB Type-C interface which can supply power and also download code. On top of that, there are power pads at the back of the XIAO which support battery and makes designing wearable tools simple and easy. Aside from the power LED, we likewise included an individual baited board for far better coding experience.
Generally a Dev. Board as little as this size will make use of the chip’s internal crystal oscillator for time fixing, in order to make the clock a lot more accurate, Seeeduino XIAO layouts an extra 32.768 Chaz to make the clock much more secure.As well as of course, the Seeeduino XIAO is completely suitable with Arduino IDE which enables you to conveniently establish little jobs with the help of the huge as well as comprehensive Arduino library.
