There are two interfaces for transmitting data to the backpack: USB and Serial. USB is the easiest: simply plug a mini-B cable from the backpack to a computer to power and connect. The backpack will appear as a "USB Serial Port" to Windows, Mac and Linux computers. An INF file is required for windows, no driver is required for Mac or Linux. Windows computers will create a '''COM''' port, Mac/Linux will create a device under '''/dev/cu.usbserialXX''' or similar, run '''dmesg''' right after plugging in to see what the device is called. With USB, use any terminal progam to connect at any baud rate to the port and send text and command data. The baud rate is not used for USB so just connect at 9600 or whichever is easiest.

You can also connect with the TTL serial input. This is the red/black/white cable. Power is provided by connecting the black wire to ground and the red wire to +5V. The white cable is the 5V TTL serial input. By default, the backpack is configured for 9600 baud, 8 bit, no parity, 1 stop bit. You can configure the baud rate if you need faster/slower TTL interface. When powered, the backpack will blink the baud rate onto the display for 100 milliseconds so if you're ever really confused, connect while watching the display. You can always connect with USB (baud rate is not used for USB) and reset the baud rate there.

For hard-wiring the USB connection, there is a USB breakout in the standard '5x1' pinout for red, black, white, and green USB wires. For hardwiring the TTL connection, there are breakouts for the RX and TX pin. along the edge of the PCB.

+Par défaut, le backpack est configuré en 9600 bauds, 8 bits, sans parité, 1 bit de stop (8N1). Il est possible de configurer le débit (''baud rate'') si vous avez besoin d'une liaison série plus rapide ou plus lente. Lorsque le backpack est alimenté, il affiche le débit (''baud rate'') pendant 100ms sur l'afficheur... donc, si vous ne savez quel est le débit en vigueur, regardez l'afficheur pendant que vous le mettez sous tension. Il est toujours possible de connecter le backpack en USB (où le débit/''baud rate'' n'est pas utilisé) et de reconfigurer le débit via la connexion USB.

+=== Connexion Série directe ===
+Si vous voulez réaliser une connexion série sans utiliser le connecteur série à votre disposition, sachez que les broches RX et TX sont accessibles également sur le bord de la carte.
