How ArduPilot Mega IMU shields and mainboards are tested

Posted by Chris Anderson on June 9, 2010 at 10:00pm

Making boards of the complexity of the ArduPilot IMU shield takes more than a pick & place machine. It also requires a test jig to verify that every board is working before it's shipped out. Here's a board from the first batch being tested. Those pins inbetween the two red boards are called pogo pins, and they're spring loaded, allowing us to just press the new board on the top to make an electrical connection.


Here's a shot from the side. The board in the middle is running the test code:



This is the one Sparkfun uses for the ArduPilot Mega main board, which they gave us so we could make our own main boards, too. Sparkfun makes the best test jigs and they've taught us a lot. Yay Sparkfun!



The final product! ArduPilot Mega IMU shields getting ready to be shipped out--is there anything more beautiful?

    Chris,

    Would it be possible to make your IMU Mega test software available, assuming it will run on an ArduPilot Mega, to check out our ArduPilot Mega/IMU Mega integration and functionality once we get the headers installed and the two modules plugged together?

    Just a thought.

    Regards,
    TCIII

    as someone that works in the electronics production field I'm cringing at the sight of the boards all stacked one on top of the other. lol

    Fantastic test cards gents - great ingenuity as well - great way to avoid the ghastly price of probecards!

    HappyK, he's now moved to a much bigger house in San Diego. Our "factory" now has its own whole room! (just a garage, true, but there's a rich tradition there ;-))

    @Gary, I always wondered if she would have become as famous if she had kept the red hair?

    Cool that she worked on drones before she worked on Kennedy. (sorry, that was a bad one, I know)

    Chris, does Jordi still have a bed in his new place? Seems like it might be time for manufacturing and warehouse space!

    @Chris the third one from the left is mine, can recognise it from here

    @Chris what is the timeline for shipping for this first batch? I'm like a little kids waiting for x-mas.

    sure hope the board in the test jig isn't being sent out!! no Acel! :) Can't wait for mine!
