Testing - QRP Labs QLG2 Manual

6. Testing

All QLG2 modules are tested by QRP Labs in a custom-designed test jig. The test jig
is used for firmware flashing, and connecting to the GPS antenna and USB connector.
These connections are achieved by ten pogo pins installed on a special PCB. Four 3mm
screws in each corner of the boards ensure accurate alignment, and the PCB under test is
secured in place and under slight pressure (to press the pogo pins) using four 25mm nylon
spacers. There is a push switch to connect power from the USB connector.
The following pictures show the test jig, and then the test jig with QLG2 board under test.
