* '''GND''': this it the common ground pin, used for power and signal reference ground. Make sure in your system all grounds between microcontroller, battery/power and the EZ-Link are connected
+
* '''GND''': C'est la broche de masse commune, utilisée comme référence de masse pour l'alimentation et les signaux. Assurez-vous que toutes les masses de votre montage soient commune entre le microcontrôleur, aliementation, accis et EZ-Link.
* '''DSR''': this is the "Data Signal Ready" hardware flow control pin that is transmitted from the Microcontroller, through the EZ-Link to the paired computer. If you want to send a signal outside of the UART back to the computer, this pin can do it. The computer can then read the terminal-status lines. This isn't a high-speed line, expect up to 100ms delay from when the pin toggles to when the signal is read on the computer. If not used, tie to ground.<br />On FTDI cables this is often labeled CTS, for a different signal line. Bluetooth does not have support for sending this signal back to the computer so we substituted DSR instead.

* '''DSR''': est la broche de contrôle de flux matériel "Data Signal Ready". Signal envoyé par le microcontrôleur vers l'ordinateur/hotes appairé via l'EZ-Link. C'est la broche de signal à utiliser si vous voulez envoyer un signal depuis l'UART vers l'ordinateur/hôte appairé. L'ordinateur appairé poura alir lire le statut de la ligne terminal (''terminal-status lines'').<br />Il ne s'agit pas d'une ligne à grande vitesse, comptez sur un délai de 100ms entre le moment où la le signal est basculé et le moment où il est lisible sur l'ordinateur appairé.<br />Raccordez ce signal à la masse si vous n'utilisez pas ce signal.<br />Sur un câble FTDI, le signal est souvent libellé CTS (''[http://ulisse.elettra.trieste.it/services/doc/serial/rs232.html Clear To Send]'') pour une ligne de contrôle différente. Bluetooth ne dispose pas de support pour renvoyer un signal vers l'ordinateur appairé... raison pour laquelle Adafruit lui a substitué le signal DSR.
 
* '''Vin''': This is the power pin into the Bluefruit module, it passes through a 3.3V regulator so this voltage can be from 3.3V to 16VDC and is reverse-polarity protected. If a battery is connected via the optional JST connector on the back, this pin becomes an output so you can power your microcontroller/project via the battery.<br />If you plan to use the optional JST connector on the back, don't provide power to this pin from the microcontroller

* '''TX''': This is the serial UART output pin that is transmitted from the paired computer, wirelessly to the Bluefruit and out this pin. It is 3V logic level so you can use it with 3 or 5V microcontrollers.
