Great way to add bluetooth to your Arduino project Review by Scott

First, let me say that all my Arduino projects have been with the UNO variant. The original UNO is a bit limited, both in connectivity and function, which is why products like Iteaduino and Iteaduino BT are so great. I just bought my first Iteaduino BT and set it up yesterday. My computer is a PC running Windows 7 64 bit. At first, when I connected the board to the USB port, it seems like the computer recognized it, but couldn't load the right driver. It took many attempts before the driver finally loaded and the board was given COM8. I think they should figure out why I had so much trouble and put it in the documentation how to set it up correctly. The first thing I did was write a simple sketch to control a LED attached to digital I/O 8. Send the letter 'a' to turn it on and 'b' to turn it off. When tethered to the PC, it worked fine. I simply typed 'a' or 'b' through the serial monitor. When I disconnected it from the PC and used my android cell phone app (SENA BTerm) to connect, it wouldn't listen to the 'a' or 'b' commands. I didn't know why it wouldn't work, so as a test, i moved the two jumpers from position A to position B, while keeping the switch in the DAT position. That worked.My simple program now communicates with the board. I hope this information helps other users of this board. I love the boards from ITEAD. The extra breakout pins and the extra rows of holes next to the IO pins make these boards better than the original Arduinos. (Posted on 8/6/2014)

Excellent card, horrible documentation Review by Benjamin

I really enjoy this board for many reasons:
- Its price is reasonable, lower that Wifi, Ethernet or ZigBee.
- It does not require to load any library so it takes 0Kb on the 32Kb and leaves plenty of bytes for your program.
- It uses a standard serial port so it is very easy to use.
- It does not use any digital nor analog I/O so you can put any shield on top of it.
- You can use a wide range external input from 7~23V DC (External 7V, 9V, 12V, 24V or USB 5V).
- It has extra pins out for anything you need (I use them to connect to a digital camera).
- So far it’s been 100% compatible with official Arduino UNO.

Once you know how to use it, it is really great. I use it with my Android phone.

I wrote a blog post to configure it : http://techwatch.keeward.com/geeks-and-nerds/how-to-configure-and-use-an-iteaduino-bt/ (Posted on 8/10/2012)
