Filter Modulator build
There are 2 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 to get one but there will be a delay whilst they are manufactured and tested - current estimate for delivery due to Chinese New Year is mid February 2017 .
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.
To use the facility, sign in to digikey (you will need to register first) and go to my basket and follow these instructions. Once uploaded the Portsdown BoM will look like this:
- Change the First part Record begins on Row to "2"
- Use the column drop down boxes to match the first 3 column titles of the .xls file. Note the final 2 columns are for our reference only - on some tape and reel components you ordering more parts than required as this is the most economical price break - you can change these in the .xls if you require.
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.
