Arduino UNO Rev3 (SMD Atmega328) – online India

The Arduino UNO R3 (SMD) is the more popular with students as it is a cheaper alternative to the Arduino UNO R3 Atmega328p DIP version. Rest the same, in both the versions of Arduino but one, have the Atmega chip removable and SMD one is soldered (non-removable). Use a USB cable to power and program this board. This product comes without a USB cable, which you can buy here.

Here you can buy the Arduino UNO R3 (SMD) (Without USB cable) online in India. Order multiple products and save per-item shipping cost in India. Local Pickup is also available in Delhi-NCR.

SAVE MORE! By buying the combination instead, see below for this offer.



Arduino UNO Rev 3 (SMD Atmega328) is an open-source (i.e., all the schematic and codes are available in Public domain) microcontroller board that you can buy online in India at Circuit uncle.

This product is without USB cable, but you can definitely buy a USB cable for Arduino UNO/MEGA by clicking the link.

Technical Specifications of Arduino UNO SMD version is the same as the DIP one:

Microcontroller: ATmega328P – (an 8-bit AVR microcontroller)

Operating Voltage: 5V

Number of Analog Input Pins: 6 (A0 – A5)

Number of Digital I/O Pins: 14 (Out of which 6 provide PWM output)

DC Current on I/O Pins: 40 mA

DC Current on 3.3V Pin: 50 mA

Memory: 32 KB (Flash) (0.5 KB for Bootloader), 2KB SRAM, 1KB EEPROM

Clock: 16 MHz

The key difference between the DIP version of Arduino UNO and the current Arduino UNO SMD version is that this is a low-cost alternative to the former.  The SMD version is more popular among students as it is a low-cost alternative version of Arduino UNO. But if the Atmega328p IC got burnt, you won’t be able to remove and resolder it in order to make it working again. In the DIP version of Arduino, it was just plugged and play (which is really convenient if you face an IC burnout). So if you are looking for a long term investment, not just use and throw products please consider the DIP version of Arduino UNO. This advice you won’t find anywhere else in the market, as many vendors don’t care after the sale. Arduino UNO once got into the market in 2005 have been adopted, as the favorite microcontroller board around the world and India. Arduino is very famous among Indian students, Indians educators, because it has an open-source Do-It-Yourself (DIY) appeal, easy to program and a lot of references, and is available online.

Many other variants of Arduino are available in the market, such as Arduino MEGA or Arduino Nano but the most favorite of all time is Arduino UNO.

Fun fact associated with Arduino: Since it is all open-source, you can design board using the same open-source schematic under your name, i.e., if your name is “Mark” then you can develop or make an Arduino as “Markduino”. Arduino UNO is so easy to use, and so many pins are provided with it that it can be interfaced with multiple electronic components at once. Although having a variety of libraries already written for it,  if one is not available one can easily design them, by following these few steps.

So if you want to buy Online Arduino UNO (SMD) (A low-cost Arduino UNO) in India circuit uncle is ready to serve you. With us, you get excellent tech support and suggestions for your projects together with fast shipping so that you can get all the electronics components at your doorsteps.
