Summary:
Arduino Uno made in China.

The Arduino Uno is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter.
Revision 2 of the Uno board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode.
Revision 3 of the board has the following new features:

  • 1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible with both the board that uses the AVR, which operates with 5V and with the Arduino Due that operates with 3.3V. The second one is a not connected pin, that is reserved for future purposes.
  • Stronger RESET circuit.
  • Atmega 16U2 replace the 8U2.

"Uno" means one in Italian and is named to mark the upcoming release of Arduino 1.0. The Uno and version 1.0 will be the reference versions of Arduino, moving forward. The Uno is the latest in a series of USB Arduino boards, and the reference model for the Arduino platform; for a comparison with previous versions, see the index of Arduino boards.

The package contains:

  • Arduino Uno R3(China)-1
  • USB A to B cable-1
Microcontroller ATmega328
Operating Voltage 5V
Input Voltage (recommended) 7-12V
Input Voltage (limits) 6-20V
Digital I/O Pins 14 (of which 6 provide PWM output)
Analog Input Pins 6
DC Current per I/O Pin 40 mA
DC Current for 3.3V Pin 50 mA
Flash Memory 32 KB (ATmega328) of which 0.5 KB used by bootloader
SRAM 2 KB (ATmega328)
EEPROM 1 KB (ATmega328)
Clock Speed 16 MHz

Hello Techshop Admin,

1.Will this board (Arduino Uno) support ATmegaA8 and ATmega168 micro controllers ?

2. Is ATmega328 and ATmega328P are same chip ?

3. If I buy ATmega328P micro controller form Techshop, will you burn the bootloader in it before shipping (for Arduino Uno R3 board) ?

4. Please check this link :
http://arduino.cc/en/Tutorial/ArduinoToBreadboard

Is this the method to burn bootloader in ATmega328P ?

Please reply.... I will be waiting for your answers !
anon
A.R | Jun 23,2014 at 10:35 AM
1)Do you mean that you want to remove the Atmega328P from the board and place ATmega8 or 168 instead? If so, then the answer is No.
2. No. Pinouts are same but these two ICs have different signatures.
3. We are planning to sell Atmega328 with arduino bootloader. Those are supposed to be uploaded soon.
4. Yes. These methods will work.
anon
Saadman672 | Jun 26,2014 at 10:28 PM
please help by answering those questions:
1. are all those AVR boards are more or less same?
2.can I remove the MCU with out desoldering? that means only by hand?
3. if the answer of question 2 is yes then;can i program it on that board and and remove it and then then install it on a breadboard to use it?
4.if the pinout config of any other MCU is same as the ATmega328, can i program it by this board?
5.on a site i noticed that it is possible to configure the bootloader form this board to non programed MCU on a bread board. pls tell me that this method is applicable for MCU with of same model or for every AVR MCU?
6. and the final question is: im actually a student from business studies so it is vary hard fro me to understand this items. is it possible to program this board with c or c++ ?(as those are the only languages that i know a little). and actually what kind of programming language is used to config that boards??
anon
A.R | Jun 27,2014 at 04:54 PM
Very much confusing questions but I am trying to answer one by one:
1) Are you talking about our AVR programmers? If so, then let me tell you, each of the AVR prorammers available here has different technical features but the list of supported micrcontrollers are almost same which can be found at our website or at our suppliers' site.
2)Which MCU are you talking about?The programmer IC? That is the heart of every board! If you take that out your board will not work. However, Progammer ICs are not soldered to the board. So, those are removable.
4) Arduino is not meant for being used as an AVR programmer!
5) You will get the idea from here http://arduino.cc/en/Tutorial/ArduinoToBreadboard
6) I will request you to go through our basic tutorials on arduino if you have not gone through them yet. You will get the basic idea of coding.

Recently I have bought Arduino Uno. But suddenly I have found that Arduino Mega 2560 has a lot more memory than Uno. Will there be any problem with less memory in Uno then Mega for small and medium project? If so, can I exchange my Uno with Mega 2560 and what is the procedure? Please explain. Thank you.
anon
Suntop | Aug 5,2014 at 09:58 PM
I don't know what you are planning to do ! But sticking with Arduino Uno is the better choice unless you need more than 14 I/Os (actually 20 I/Os).

Because This Arduino Uno board is reusable, once you have programmed the AtMega328P MCU (the removable chip) you can remove it form the Uno board and use the chip on breadboard/PCB with your project. All you need will be a 16Mhz crystal and 2 22pf capacitors to run the chip outside Uno board. And connect your project components with the MCU's pins by following Datasheet !

Again, you can reuse your Uno board by putting a new AtMega328P MCU for another project (bootloader to be burned) !

In this way you save money !

32kb is fair enough for most project unless you are doing advanced big projects !

From my personal experience I assure you less memory won't be a problem if you program efficiently.

Go for Arduino Mega 2560 if your are

1.Connecting 1+ Display units
2.Going to code 300+ lines of codes
3. Need more than 100+ variables (specially unsigned long)
4.Need to control many separate processes

This is my personal opinion so do as you please

Please check this links if you stick with Arduino Uno

http://arduino.cc/en/Tutorial/ArduinoToBreadboard

one more think.... with Arduino Mega 2560, if you short circuit I/O your board may be dead forever, with Uno if you make mistake, probably spending 200 taka for AtMega328P MCU you may revive it again !

A.R | Aug 6,2014 at 11:05 AM
You can return your Uno and order mega. You will get your money that you paid for uno back. Please note that we cannot return the vat that we took from you. And let us assure you that UNO works pretty fine in professional projects.
anon
Nazmul_eee | Aug 12,2014 at 02:15 AM
Thanks for the information. Your last point sounds reasonable. I didn't think of mega 2560's compactness. Uno board IC is removable. But mega doesn't provide this facility.

anon
Suntop | Sep 30,2014 at 01:15 PM
There are few ways you can power it up :

First and the most common method is to power it from USB port of your computer

For, portable applications use a 9 V battery with LM7805/LD1117/78L05 voltage regulator to get 5 volts

For static & continuous application use any 5V adapter with at least 300-500 mA current output. You may use your cellphone charger too ! (check voltage before powering)


anon
Suntop | Sep 30,2014 at 01:19 PM
If you want to power the uno using its on board power port use DC power jack and supply DC voltage between 7-12 Volts.

- outside (outer shell)

Well, Atmega8L is actually intended for up to 8Mhz clock although it worked for me @ 16 Mhz. You may try on breadboard with 8Mhz xtal . Also reburn the boot loader and try again . make sure reset pin is pulled up to Vcc with 10 k resistor . check connections. Most importantly select the right board from your Arduino IDE and update your arduino 'board text ' with proper Chip parameters (see Google ) . upload holae kaj hobe amon kono kotha nai !

You are using old bootloader on your chip (NG / Atmega8) . if you can follow the instructions above about burning Optiboot8 follow that ! There is nothing wrong with the delay you are getting right now ! If was a feature useful in old days , that was used by arduino to wait for new sketch during startup ! Either burn new bootloader or don't ! (Check my 30 the DEC post )

This is a fake ardruino.Ardruino is an open source hardware and everyone can assemble their own.....the component beside the usb port is supposed to be golden,not green as shown in the picture.

Excuse us, aren't we crystal clear enough by writing china within the bracket? Everyone knows and understands that it is a chinese copy. How is someone supposed to get real arduino in 850 Taka only? Come on! Of course we sell the real one and here goes the link. https://www.techshopbd.com/product-categories/boards/1281/arduino-uno-r3-original-techshop-bangladesh
We do fair business exposing the origin of the products so that people can distinguish and take decision. It's not our responsibility if someone still fails to understand.

So if i buy a bootloaded IC ATmega328 will my arduino work again or i need to buy another one??

FAHIM_REAZA | Aug 3,2016 at 04:48 PM
The "ATmega328p" on arduino, is pre-installed boot-load system. So why you are trying to boot-load.
From your above comment, we are not clear that the problem is on "ATmega32p" or "Arduino Development Board" !!!
If the problem occur in the "ATmega328p" chip, then if you buy a boot-loaded ic, it will be work again. To buy a boot-loaded ic, please click the link bellow:

স্যার,
আমি আপনাদের কাছ থেকে একটি ' Arduino UNO R3 কিনেছি।সেটায় একটা সমস্যা দেখা দিয়েছে। সমস্যাটি হল:
অরডুইনোটি যথারীতি আপগ্রেড দেওয়ার পর প্রায় সিব টিউটোরিয়াল এর সাজেশন অনুযায়ী আমি 'Blink' প্রোগ্রামটি আপলোড দেই এবং সেটি ঠিকমতোই কাজ করছে।কিন্তু সমস্যা হল,এখন আর কোনো নতুন প্রোগ্রাম আপলোড নিচ্ছে না।যেখানে আপলোড সেকেন্ডের কাজ,সেখানে প্রায় ৫ মিনিট ধরে আপলডিং দেখিয়ে এরপরে শো করে,"Uploading eror" অথবা "problem uploading the board "
অনেকবার অনেকভাবে চেষ্টা করেছি। অরডুইনো সফটওয়্যারটি আনইন্সটল করে আবার ইন্সটল করেছি,বারবার আপলোড করার চেষ্টা করেই যাচ্ছি,একই অবস্থা।
কি করা উচিত আমার???

I am disappointed with this product. I ordered a Arduino last sunday , the built in led was not blinking, the rx and tx was not responding. Then i changed it and now most probably because of the bootloader the pin 13 led is always on . I am currently working on a ir reciever project and i am getting junk values on the serial monitor . This is what i did: i connect the middle pin to GND pin 3 to vcc and pin 1 of the ir receiver to pin 11 of the arduino

I know that, the arduino was opened when i received it. At first i tried the blink sketch
it worked, then i tried a digital read sketch that worked but then i noticed that the pin13 led was still blinking but the sketch worked. But when i tried to serial communicate using a ir receiver i could not get the values , suddenly i used to get a value .The board also has a bright red led instead of the green one.
