Filter Modulator build

There are a number of ways to get a Portsdown filter modulator board which is the only custom hardware required for the project.

• Once the design is finalised, built and tested Portsdown modulator boards will be available from the BATC shop This is the easiest way but there will be a delay whilst they are manufactured and tested.

For those wanting to construct the board themselves, the blank PCB will also be made available from the BATC shop

• Below is a bare bones parts list, or Bill of Materials, as an .xls file which you can upload to Digikey - you then simply checkout and pay Digikey and it will automatically order all the parts you require to construct the board which will arrive bagged up marked with circuit references.

This is the recommended way to order your parts if you decide to build the board yourself but you can of course order the parts from your own supplier.

Note we have limited stocks of the blank PCB at this time and are unlikely to get any more until after Chinese New Year ends on Feb 4th 2017.  We suggest you may not want to order any components until you have confirmation of a PCB being available for you.
