Adafruit trinket pro timer example1/4/2024 It lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one. Operating at 16 MHz with 32KB of program memory, 1KB of EEPROM, 2KB of RAM, 14 digital I/O, 6 analog inputs, and both 5V and 3.3V rails, the Arduino is packed with peripherals for its size It has more or less the same functionality of the Arduino Duemilanove, but in a different package. If you have a code from your previous Uno project, you can easily move it to the Nano! Basically, you can think of the Arduino Nano as an Arduino Uno that has been shrunk into a very small profile which makes it convenient for tight spaces and projects like wearables, mini robots, and many more. Seeeduino XIAO Family Seeed XIAO RP2040Ĭoming in first, we have the small, complete, and breadboard-friendly board, the Arduino Nano which is based on the same ATmega328 as the Arduino Uno. The best news is, you can get all features packed on a tiny board this just for only $5.40! Wow! Specs: Specs And of course, the Seeeduino XIAO is perfectly compatible with Arduino IDE which allows you to easily develop small projects with the help of the large and comprehensive Arduino library. Usually, a development Board as small as this size will use the chip’s inner crystal oscillator for time fixing, in order to make the clock more accurate, Seeeduino XIAO layouts an extra 32.768KHz to make the clock more stable. ![]() Other than the power LED, we also added a user LED on board for a better coding experience. In addition, there are power pads at the back of the XIAO which support batteries and make designing wearable devices easy and simple. The Seeeduino XIAO supports the USB Type-C interface which can supply power and download code. The board is also breadboard compatible which is very rare for a small board like this! Some PINs have various functions, A1/D1 to A10/D10 Pins have PWM functions and Pin A0/D0 has a function of DAC which means you can get true analog signals, not PWM signals when you define it as an analog pin, that’s why 14 GPIO PINs can realize more I/O PINs and interfaces. Despite being this small size, it has 14 GPIO PINs, which can be used for 11 analog PINs, 11 digital PINs, 1 I2C interface, 1 UART interface, and 1 SPI interface. Seeeduino XIAOĪpart from the strong CPU, Seeeduino XIAO is excellent in many other functions. Without further ado, let us jump into the first board!įirst of all, the No.1 product that I strongly recommend to you is Seeeduino XIAO and the products of the XIAO family. Here is the list of boards we are going to look at: In this comparison guide, we will cover the following smallest Arduino boards currently out there in descending order from small to smallest. Which one should you use?įacing the same problem, I decided to come up with this comparison guide whereby I compare various small Arduino boards currently to find out which smallest Arduino is the best where we evaluate their capabilities and also their pros and cons. Have space constraints on your Arduino Project? Need a small Arduino board? However, there are so many small Arduino boards out there currently out there. ![]() Before you move on, if you have no idea what Arduino is, you can check out our guide on What is Arduino to find out more!
