Bill of Materials

The QCC-100 can be built into either an internal or dongle version. The internal version is placed inside the DRO-350 case and is connected to the the DRO-350 PCB with either solderless connectors or directly soldered wires. The dongle version is designed to be plugged into the mini-DIN connector on the outside of the DRO-350. The total cost of the parts common to both versions is $6.96 from Digi-Key.

Internal Version

The internal version can be built with or without the solderless connectors. The solderless connectors add $0.74 but note that a couple of the solderless connectors must be ordered from Digi-Key in quantities larger than needed. This will add two dollars to the total cost for a single QCC-100.

* This part is not available from the vendor in single quantities and must be purchased in larger quantities at the price shown in parenthesis.

Dongle Version

The dongle version uses a male mini-DIN plug to connect to the DRO-350 and a female mini-DIN plug to connect to the quadrature encoder. The female mini-DIN plug has the same pin-out as the female mini-DIN connector on the DRO-350 when the internal version is used. The dongle can be easily built with a connector other than the female mini-DIN to better suit a particular quadrature encoder.

Order Tool

The order tool allows you to automatically submit the components in the BOM to Digi-Key. To use the order tool, enter the number of QCC-100's that you would like to order components for and select the radio button for the version. Click on the submit button to place the order at Digi-Key's web site. Please be patient after clicking on the submit button since it sometimes takes a few minutes for Digi-Key's web site to accept the BOM.
