Radio Connector Part Numbers

If you decide not to use the terminal strip on the back of the motherboard to connect the 2nd channel, you can use the radio connector J11 instead. Both radio channel connectors (J10 and J11) are double row 0.1" center header patterns. They are double row simply to make it easier to cut the traces between the rows if necessary. Once the traces are cut the header should be soldered into the row that is farthest away from the card-edge connector fingers.

To use a connector instead of the terminal strip you should cut the traces between the row of holes on the back of the board to isolate the terminal strip from the board. A Dremel tool is good for this (be careful not to cut too deep) or an XActo knife also works well. Be careful as it is easy to cut yourself if using an XActo knife.

Headers

The J10/J11 header patterns on the board accept the following standard Molex header. The DigiKey part number is given as well as the Molex part number so the part could be ordered from Mouser or other electronic suppliers:

Digikey WM4117-ND, Molex 0022272001

Be sure to solder the connector into the header row that is farthest away from the card edge connectors fingers.

Housing and Pin

The following part is the housing used on the pigtails that connects to the header above. Again both the DigiKey and Mouser part numbers are given. There are actually two parts: The first one is the housing, the second one is for the pins that connect to the wire and insert into the housing.

A total of 8 pins are needed for each housing:

Digikey WM2006-ND, Molex 0022013087 (Housing)
Digikey WM1114-ND, Molex 0008500114 (Pin)

As an alternative to using these connectors, the user may simply solder wires directly into the connector holes and then attach the user's choice of connector to the wires. Be sure to solder the wires into the header row that is farthest away from the card edge connectors fingers.
