The OSEPP™ Uno R4 Plus board is the most popular Arduino board out in the Arduino market! This board uses the 8-bit, AVR, RISC-based ATmega328P microcontroller from Atmel.New features in R4:
New Features in R4:
• ATMEGA 16U2 Chipset
• Micro USB connector
• 4 additional 5v and GND power pins
• Additional analog pins A6 & A7
“Plus” Features:
• Replaced mini-USB connector with the more popular micro-USB connector
• removed the Molex connector
Highlights:
• 8-bit AVR RISC-based microcontroller running at 16 MHz
• Connects to a computer via a standard USB cable
• Flexible power source (USB or DC power)
• ICSP header for programming microcontroller
• Compatible with existing Arduino software libraries
• Compatible with all Arduino shields make for Arduino UNOs.
Features:
- The ATmega328P comes with the Arduino bootloader preloaded. There is an ICSP (In-Circuit Serial Programming) header for the ATmega328 to optionally replace the bootloader.
- As an added precaution, the board comes with a resettable polyfuse on the USB connection path. To prevent damage to the USB port, the fuse will trip when the current to the port exceeds 500 mA.
- The input and/or output pins are brought out to the headers, providing a convenient way to prototype projects without the need of soldering or desoldering.

What You Need
- Arduino Software (http://arduino.cc/en/Main/Software)
- USB-to-mini-USB
- PC/Mac with a USB port
Uploading Your First Sketch
- Get the Arduino software if you have not already
- Download from http://arduino.cc/en/Main/Software
- Unzip the zip file to somewhere like C:\ (on Windows), so you will end up with a folder like C:\arduino-0022
- Prepare for serial communication
- Connect the USB-B end of the cable into the board
- Connect the other end of the cable into a USB port on your PC/Mac
- If your computer prompts for drivers, point it to the “drivers\FTDI USB Drivers” subfolder of the Arduino software, e.g. “C:\arduino-0022\drivers\FTDI USB Drivers”
- You should now see the LED labeled ON near the reset button light up
- Load the sketch
- Open the Arduino software
- Open the LED blink sketch: File menu > Examples > Basics > Blink
- Select the Arduino/Genuino Uno: Tools > Board > Arduino/Genuino Uno
- Select the serial port: Tools > Serial Port. This is the serial port for the board’s built-in FTDI. If you do not know which one this is, you can find out by going into Device Manager > Ports (COM & LPT), and look for a “USB Serial Port (COMx)”
- Upload the sketch: File > Upload to I/O Board
- Wait for the “Done uploading” message in the bottom blue status bar
- The LED labeled L near pin 13 should now blink slowly
- Congratulations! You have successfully uploaded your first sketch to your board.
