Firefly Ice Blue: Test Fixture

Posted by Denis Bohm on February 05, 2014. 0 Comments

The test fixture is used during production testing and programming.  It has spring loaded pins that make contact with the test points on the PCBA.  A plastic adapter holds the spring loaded pins in place and guides the PCBA into place.  This design makes it easy to momentarily hold the PCBA in the test fixture while the testing and programming take place.  The test points are brought out to a standard JTAG SWD connector, USB connector, and battery connector.  There is also a reset button.

The following image shows the test fixture with and without the PCBA in place:
