Arduino Uno R3 development board

Arduino Uno R3 is probably the most well-known microcontroller board in South Africa. The R3 is the latest Arduino version to date and the board you will use most when developing microcontroller projects. This board is the heart of almost all the products we sell here at Bot shop, it is easy to develop with, robust and has a huge community behind it.

Arduino Uno R3

The Arduino Uno R3 is a microcontroller board based that are based on the ATmega328P (datasheet) chip used mostly for development and prototyping. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, 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 an AC-to-DC adapter or battery to get started. You can tinker with your Arduino UNO R3 without worrying too much about doing something wrong, the worst case scenario you can replace the chip for about R35.00 and start over again.
You can download the IDE software for free on the Arduino official website.
This board is a 100% identical clone and not the original Arduino Uno. We sold many of them and had no problems with these boards. they are high quality 100% identical but at a much better price. You can be confident that these boards work just as well as the original.
If I may be bold to ask - please donate when downloading the software, the Arduino guys do not make any money out of these clones (but 100% identical boards) we sell. You can donate as little as $3.00. Think of it this way - you can get all the Arduino software and upgrades for the rest of your life for only $3.00. Yes, you can get it free but your $3.00 make this a win-win thing for all. On the Arduino IDE download page is an option to donate Arduino - Donate.
