Power socket on Rosetta

[Chrisboz]

Hi,
Couldn’t get my power lead to work today, works ok if I hold it in place but then as soon as let go to natural plug in position of lead it loses power, tried another lead same thing so does anyone know if there’s a fix for this or is the whole unit u/s,
Any help appreciated

The are fixes for this but they are for the technically gifted, they involve soldering to fix the damaged micro USB if it's that or injecting the +5V via another part of the device.

I'd pick up the phone or email PAW support if I were you...

Don’t think I’ll go down the fiddly route of solder etc

I take it if I replace the raspberry unit, it’s just modular inside the case and fairly easy to take apart and plug back together,
I’ve read other answers to contact support to update the MAC address for new unit?

The USB sockets on the Pi's can be changed, but you need a hot air re-work station.  I've replaced quite a few when Pi's were in short supply.

Sometimes, the solder joints break, so it only needs a slight touch-up with a fine-tipped iron; other times, the sockets do need replacing.

I have a similar problem. Despite using recommended/supplied JuiceBlitz USB-A to micro USB cable, the shows "low voltage" when power comes on. Only pulling out the micro USB male connector from Rosetta, and reinserting it removes the "low voltage" warning. (Removing and reinserting the USB-A connector from the power supply does typically *not* solve the problem.)

We want to have a look. But how does one even open the Rosetta plastic enclosure? I manage to pull of the cover that is over the GPS/SDR side, but struggle to see how the main box opens...

Should we consider hardwiring the power cable to the circuit board?

Should we consider hardwiring the power cable to the circuit board?

There are instructions elsewhere to hard wiring the power directly in, but again, for technically able, please don't destroy your PAW in the process of soldering if you are not sure, or break it trying to get it open.

Unlike a normal Pi there is a daughter board in the case with the main RF stuff on it.

I'm wondering if using a proper electrical contact cleaner spray will solve your problem, but again, it's a risk... from memory, the case is clipped together.

IF you replace the Pi motherboard you will need to get an update to the licence before the software will work again...

I use this for cleaning contacts and fibre ends in broadcast, but it's your call:

Maybe PAW staff can come in here with an authoritative answer:

- How to open the main case?
- Where is the topic that discusses hardwiring the pet into the Rosetta (not into the supply side)?

Here's a hardwiring discussion...

Many thanks!  And how does one open the Rosetta Main case?

[Vic]

Remove the two nuts securing the antenna connectors.

Remove the lid over the USB connectors

The case is merely clipped together at the seam that goes through the line of the HDMI connector. Gently prise it apart all around using the blade of a penknife or similar.

And don't forget to take out the Micro SD card first.
