The OSEPP Nano is a breadboardfriendly downsized version of the Uno board with much of the same functionality. The main workhorse is still the ATmega328P; however the number of analog pins has gone up from four to eight. The other difference is the lack of a DC power connector. Highlights: 8bit AVR RISCbased microcontroller running at 16 MHz Single miniUSB connector for both power and serial communication Form factor is breadboard friendly Less than 1/3 the size of the OSEPP Uno Two extra analog input pins compared to the OSEPP Uno Compatible with existing Arduino software libraries Features: The ATmega328P comes with the Arduino bootloader preloaded. There are ICSP (InCircuit Serial Programming) pinouts for the ATmega328 that can be used in conjunction with a header (sold separately) to optionally replace the bootloader. The input or output pins can easily be brought out by soldering 0.100in headers to the pads. The board was designed to easily fit breadboards with the headers soldered on.

This is the serial port for the board’s builtin 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.
