A Bluetooth module that can change baud rates on the fly and toggle the DTR pin as desired!
The Bluefruit EZ-Link is a regular 'SPP' serial link client device, that can pair with any computer or tablet and appear as a serial/COM port (except iOS as iOS does not permit SPP pairing) with some lovely extra features
What we've got here now is a way to program an Arduino (or compatible) from 10 meters away, completely wirelessly, with no extra software, custom hardware, odd firmware hacks or modified firmware. In fact, you can use the Bluefruit as a sort of 'wire free' FTDI-like cable with any device that has an FTDI re-programming port. It works great, and you can use the serial console as well. This package includes the necessary 1uF capacitor between the DTR and reset pin.
Chances are you will want to solder the female header in to the center of the board so you can use it like an FTDI-cable but if not you've got the option of wires, or other kind of header.
The JST connector can be soldered on the back (optional) to connect a Lipoly battery for portable projects. If the JST is used, the battery can also power the microcontroller that the EZ-Link is plugged into.
