The FTDI TTL-232R-5V download cable (Click to enlarge)

Introduction

For downloading software into the Skycube board or controlling modular robots from the PC, the TTL-232R-5V FTDI cable is used. This cable is connect on one side to the USB port in the PC and on the other side to the Skycube board, by means of a three-pins header. Originally, this cable comes give a six-pin female straight header. It has to be changed by a three-pin header for connecting to the Skycube board. This process is reversible, so that the original cable can be recovered anytime.

Modifying the cable

Step 1: Remove the 6-pin header

The 6 wires should be pull out one. Using a flathead screwdriver lift the tap and pull out the wire.

1) Original cable with the 6 pin header (click to enlarge)
2) Lift the tap for pull out the wire (click to enlarge)
3) The black wire is being pulled out from the header (click to enlarge)
4) All the wires have been extracted (click to enlarge)

Step 2: Place the new 3-pin header

Insert the black, yellow and orange wires in the new header. It is very important to connect them exactly in the same way than in the figures. Make sure the header is in the right position, with the tabs facing up (See the pictures).

2) Black wire inserted (click to enlarge)
3) Yellow wire inserted (click to enlarge)
4) Orange wire inserted (click to enlarge)

Step 3: protect and remove the remaining wires

Put insulating tape around the metal pins of the remaining wires to avoid short circuits. Then, bend back the wires until they are paralell to the cable. Put insulating tape around them. The download cable is ready to use!!!

1) Put insulating tape arount the three remaining wires
2) The cable is ready to be used with the Skycubre board

Step 4: Put a label on the 3-pin header

It is important to put a label in the cable to identify the correct orientation for the connection to the Skycube board. This will avoid mistakes.

Conexión a la tarjeta Skycube

El conector hembra de 3 pines del cable se conecta al conector M6 de la Skycube 1.0, en la misma posición indicada en las fotografías. Para evitar colocar el conector al revés, conviene poner una etiqueta, como se muestra en la foto de la derecha.

Para hacer las descargas, la Skycube tiene que estar encendida (led rojo encendido)
