Arduino Uno R3
Buy an Uno and get a base plate (with screws) for only R5.00! Please note the colour of the base plate will depend on what we have in stock.
The Arduino Uno R3
is a microcontroller board 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, 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.
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
