Arduino Uno R3 compatível c/ Cabo USB da Funduino
The Funduino Uno is a direct (it is open source, after all) copy of the Arduino Uno R3. It is quite a bit less expensive than the original Arduino Uno R3. Although the parts are not from the same suppliers, the PCB appears to have been made from the original Arduino PCB files, with a few modifications.
The Uno is a microcontroller board based on the ATmega328P. 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 a AC-to-DC adapter or battery to get started.. You can tinker with your UNO without worrying too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again.
