Arduino Uno R3 - clone

Description Links

The Arduino Uno is a board based on the ATmega328 chip. This Uno has 14 digital input / output pins (6 of which can be used as PWM outputs), 6 analog inputs. This Arduino is very popular and is very easy to program due to the built-in USB interface. With the Arduino development software you already have your first program running within minutes.

This version has the original Atmega 16U2 'serial to ttl' chip, making this Arduino 100% the same as the original. This means that no additional drivers are needed to use this Arduino.

It concerns the 3rd revision (newest) with the following adjustments:

  • Atmega 16U2 replaces 8U2.
  • Stronger RESET circuit.
  • Added SDA and SCL pins at the AREF pin and 2 new pins at the RESET pin, namely the IOREF pin, allowing shields to adjust to the voltage from the board. In the future, shields are compatible with both the 5v and 3.3v versions. The 2nd pin is not connected and is reserved for future updates.

This Arduino is a clone, which means that this sign was not built in the original factory. The only difference between original and clones is that these Arduinos are cheaper. All components and circuits are otherwise identical.

Q The Netherlands Jeroen van SchaikAre these the clones with a 16u2 USB to serial chip? There are also some that contain a ch340 and I should not have this because of the inability to flash the keyboard and joystick simulator. View 1 answer   |   Answer this question

Works well! Works well Alle componenten zijn netjes op het board geplaatst, geen scheve aansluitingen e.d. Good price
Great thing

Good price No negatives, keep it up!
This clone is a perfect replacement for an original that gave up the ghost after 7 years. Very favorably priced. My first order with open circuit and I was impressed with the functional website. Intuitive, no/hardly any room for mistakes or getting lost. And a reorder button. Useful!! Thanks also to the thoughtfulness of the staff. I gave a wrong address. So return the package. Because the return journey can take a while, they quickly sent a new shipment. Top.

Fine, for me a first introduction, follow a course!

Works well!
It works on a power bank 10,000 ah, but I think it only works for LED flashing lights. You can simply use LED flashing lights that work on relays from 5v.

Geometrie is exact aan het origineel, dus past in standaard verkrijgbare behuizing. Alle componenten zijn netjes op het board geplaatst, geen scheve aansluitingen e.d. Niet kunnen vinden.
Just a good Arduino clone. Works completely the same as the original because it is equipped with a 16u2 chip ( USB > Serial). I have already made several circuits with this UNO and it works to my complete satisfaction. So it is not inferior to the much more expensive original.
