Lakduino UNO Rev4

World's Most Cost Effective Arduino Compatible UNO Board

This is the new Lakduino UNO R5 which is compatible with the popular Arduino Uno. In addition to all the features of the previous version, the Lakduino UNO R5 now comes with a CH340 USB-to-Serial driver chip on board so that you don't have to get busy with external connections for uploading your sketches. Simply download the drivers for the CH340 and you are ready to use it with the Arduino IDE. The Uno R4 also adds SDA and SCL pins next to the AREF. In addition, there are two new pins placed near the RESET pin. One is the IOREF that allow the shields to adapt to the voltage provided from the board. The other is a not connected and is reserved for future purposes. The Lakduino UNO R5 works with all existing shields but can adapt to new shields which use these additional pins. With new onboard SMD LED's and re-settable fuse added for USB over current protection and the Original standard PCB quality, the new Lakduino UNO R5 is no shorter in quality and class.

The Lakduino UNO R5 can be programmed over a USB Mini-B cable using the Arduino IDE: Just plug in the board, select the appropriate Comm Port from the Tools menu and you're ready to upload code. Lakduino UNO R5 has all of the hardware peripherals you know and familiar with: 14 Digital I/O pins with 6 PWM pins, 6 Analog Inputs, UART, SPI and external interrupts. You can power the Lakduino UNO R5 over USB or through the barrel jack. The on-board power regulator can handle anything from 6.5V to 15VDC.
