Arduino Uno R3 Compatible

Discontinued: This Arudino UNO is discontinued. It has been replaced by a superior model with additional features and does not require special drivers. See our Enhanced Arduino UNO R3.

We offer two versions of the Arduino UNO R3 compatible devices. One is a replica of the original UNO R3 (see UNO R3 with ATmega16U2), which does not require any extra drivers. The other unit (see UNO R3 with CH340) has the same functionality but uses a CH340 UART for the USB interface and is less expensive.
See our complete line of Arduino-compatible devices.

Arduino Uno R3 is a microcontroller board based on the ATmega328P. It features 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 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. Due to the low-cost, you can tinker with your UNO without worrying too much about doing something wrong.

Considerations

ATmega328P devices use 3.3v logic levels, unlike other devices which may use 5v logic levels. For this reason, when interfacing to other devices which will drive your Wavgat Arduino Uno R3 board. A simple voltage divider circuit is all that is required.

Setup and Configuration

The Arduino Uno R3 from Wavgat has a set of drivers which ensures compatibility. We have created a Setup and Installation Guide for reference which includes links to the Arduino IDE (Integrated Development Environment) along with drivers.
