OSEPP™ Pro Mini

IMPORTANT NOTICE:

Thanks to some of your feedback, we found out that some of our Pro Mini boards from a certain batch were loaded with the UNO bootloader instead of the Pro Mini bootloader the manufacturing process.

 

The good news is that the boards are still fully functional even with the wrong UNO bootloader (even faster according to some of you).

 

There are a few things that can be done to alleviate the problem:

1. Use the board as is and simply select “Arduino Uno” as the board type from the Arduino IDE. Since the Uno and the Pro Mini share the same capabilities (same digital/analog pin count), it will not affect the sketches that are loaded.
2. If you have access to an Atmel AVR programmer, you can burn the correct Pro Mini bootloader onto the board via ICSP. See instructions here, http://www.arduino.cc/en/Hacking/MiniBootloader

 

3. Send the board to us and we will load the correct bootloader on it for you and send it back. If you wish to follow this route, please contact us at support@osepp.com and we will make the arrangements.

 

To identify if the board has the Uno bootloader loaded, provide power to the board then press and release the reset button. If the LED next to the reset button blinks twice successively, then it is the Uno bootloader.

 

Please accept our apologies for the little hiccup.

 

 

 

What You Need

●      Arduino Software (http://arduino.cc/en/Main/Software)

●      USB to mini-USB cable

●      FTDI Basic Breakout (http://www.sparkfun.com/products/9716)

●      1×6 male pin header

●      PC/Mac with a USB port

 

Uploading Your First Sketch

1.     Get the Arduino software if you have not already

a.     Download from http://arduino.cc/en/Main/Software

b.     Unzip the zip file to somewhere like C:\ (on Windows), so you will end up with a folder like C:\arduino-0022

2.     Prepare for serial communication

a.     Connect the mini-USB end of the cable into the FTDI Basic Breakout

b.     Connect the other end of the cable into a USB port on your PC/Mac

c.     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”

d.     Connect the 1×6 male pin header to the socket of the FTDI Basic Breakout

e.     Connect the other end of the male pin header to the board, match up the pins from the FTDI Basic Breakout to the markings on the short edge of the board. Because the connection is not soldered, you will need to hold the pins at an angle so they make firm contact with the board.

f.      You should now see the red LED near the center of the board light up

 

3.     Load the sketch

a.     Open the Arduino software

b.     Open the LED blink sketch: File menu > Examples > Basics > Blink

g.     Select the Pro Mini board: Tools > Board > Arduino Pro or Pro Mini (5V, 16MHz) w/ ATmega328

c.     Select the serial port: Tools > Serial Port

This is the serial port for the FTDI Basic Breakout. 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)”

d.     Upload the sketch: File > Upload to I/O Board

e.     Wait for the “Done uploading” message in the bottom blue status bar

4.     The LED near the reset button should now blink slowly

 

5.     Congratulations! You have successfully uploaded your first sketch to your board.
