AUAV-X1 - Part IV - some AUAV-X1 board pictures and TPS63061 scopes at different voltages and loads

Posted by Nick Arsov on April 10, 2014 at 5:50am

Hi guys,

Have some pictures of the AUAV-X1 board with connectors - top side and bottom side. Also some scopes applied - input voltage from 4V to 8VDC and different loads - 0.5A and 1A.

3689585914?profile=original3689585969?profile=original3689586003?profile=original3689585994?profile=original

Some picture explanations - from top to bottom:

TPS63061_4V_1A

TPS63061_5V_0.5A

TPS63061_7V_1A

TPS63061_8V_0.5A

The temperatures are respectively - 34.5 deg C of the TPS63061, 31 deg C of the Schottky diode, 28 deg C of the inductor. They remain stable within an hour measurements. The output voltage is perfect stable - 5.05VDC. The LDO output voltages are between 3.305 and 3.312VDC respectively.

Best regards

Nick

    Hi Nick ,
         First of all, thank you to give us such a great product. I am very optimistic AUAV-X1, small size and perfect PCB layout.
         IMU stack Can I offer accessories like picture with an FPC as to achieve? Such benefits can also be independent of the IMU as a shock.
    Best regards

    Hi guys,
    I am writing this post asking for understanding and apology.

    We have to delay the AUAV-X1 project again because the stacking of a such miniature boards as IMUs is almost impossible.
    For the moment we could offer 3 IMU versions - ST set ( L3GD20H + LSM303D ) or MPU6000 or MPU9250.
    As the MPU9250 IMU uses the same pinouts as of the ST set, the code needs some mods.
    Redesigning and manufacturing a new microIMU combo ( ST set + MPU6000/MPU6500 ) will take some time.

    If some of you prefer refunding their preorders, it's o.k. We could also either compensate the preorders for stacked IMU with ACSP1 or by refunding the MPU6000 addon.

    Thanks in advance for your understanding.
    Best regards
    Nick

    The second one seems perfect but both do look very good. Can't wait for your board to have some working code... Will be awesome for gliders!

    i wish it will be ready available with arducopter code inside rapidly :)

    you board seem to be very good

    Hi Cronselaar,

    I'll highly appreciate your help with color choice. I'll change them to be most comfortable to the users.

    Please advice.

    Hi. On the front view. Avoid using red(+5V) on pink background ( use other background colour). On back view check (+3V SF). PCB view is good...

    thanks nick!

    Felix, I wish they were ready to go. That is still a pre-order. The boards are flying here now, but the IMUs still need to be sent to a US surface mount vendor in order to be finished. So close, we appreciate everyone's patience.
