Arduino UNO Mini Limited Edition

Hey maker’s Welcome back i hope you are fine ,I have got a great news for you, The world’s favorite development board Arduino has gone mini. 

As we use Arduino in hundreds of big and small projects. We have to thank the founder of arduino, Massimo Banji, because of him, we can make the biggest project using arduino board very cheaply.

As told by the official company of Arduino that Arduino UNO has been launched since 2010, after that till today. Since that time till now they have shipped at least 10 millions of Arduino UNO boards.

You know how good the journey of arduino has been when they announced the arduino then think to sell ten thousand units ,Well now they’ve sold over ten million Arduino UNO unit So they wanted something cool to celebrate this new maker board milestone. and that is Arduino UNO Mini Limited Edition.

The Arduino UNO Mini Limited Edition is a Small version of the first-class Arduino UNO board

They thought of something special cool to celebrate this day with Arduino lover and they launched the Arduino UNO Mini Limited Edition like Arduino UNO, The Arduino UNO Mini Limited edition board has similar specifications to the Arduino UNO board, and they have added a few changes As you can see in the photo given below

Changings

  1. First of all you must have noticed USB, yes USB ports have been updated to a USB-C port in this arduino mini board
  2. Second chage you can see the footprint is much smaller than the Arduino UNO Board.
  3. The female header pins are half the pitch of the original Arduino UNO
  4. It does not have plug connector for external power supply.

 It’s a limited edition, so get while it’s in stock! (BUY NOW)

Arduino UNO Mini Limited Edition tech specs

The Arduino UNO Mini is a microcontroller board based on the ATmega328P same as Arduino UNO. It has 14 digital inputs/outputs , six analog inputs pin. Simply connect Arduino mini to a computer with a USB cable, use a power adapter to get started.

As you expect, the Arduino UNO Mini Limited Edition is a quarter of the size of the original Arduino UNO footprint, measuring 34.2mm x 26.7mm x 8mm.

Hardware & Software Needed

Setup the Arduino UNO mini

 visit there official website for setup and Gide instruction. Arduino.cc/unomini

 Blink Example for Arduino UNO Mini Limited Edition

To test out your Arduino UNO Mini board, you can upload code and run the Blink code from example . 

navigate to: File > Examples > 01.Basics > Blink

Or upload the code to your UNO Mini Limited Edition board.

void setup() {
pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
digitalWrite(LED_BUILTIN, HIGH);
delay(1000);
digitalWrite(LED_BUILTIN, LOW);
delay(1000);
}

After the code upload is finished, the built-in LED will turn on and off every 1 second.

External Power for Arduino UNO Mini 

There is no jack plug for external power like current arduino UNO, But there are two pins dedicated to external power sources from the battery, Look for the VIN and GND pins at the board, and connect your power source 

Arduino Uno Mini external power

  • + to VIN
  • – to GND

If you’d like to get your own Arduino UNO Mini board , you can pre-order the board for $45 on the Arduino Store. Shipments are expected to start in early December.
