Powerboost

by ipadeflteacher on Wed Sep 26, 2018 9:41 am

I am helping a student build a Pi GRRL 2 and after soldering everything up the PowerBoost gets super hot. We desoldered everything but it still gets super hot on battery power (2500mah battery from the kit) and on USB. Only the orange charging light comes on with the battery plugged in or the usb.
I've searched all through the forums and I guess I am not the only one who has had this problem. I don't have a voltage meter.
What should I do. Unfortunately, we were hoping to have his project finished for Maker Faire this weekend but I guess that's impossible.

Please advise,

Richard

Sounds like something may have gotten shorted. Did you try testing it out before soldering it into the project?

We did. It got pretty hot then too. I read online that the PowerBoost usually gets pretty hot so I didn't think it was a problem. However, now it gets super hot that it might melt the PLA case.

Was it ever used without the battery attached? Like the Pi was wired to the output of the Powerboost and then a USB cable was plugged into the Powerboost with no battery attached.

Never got a chance to even try plugging in the USB cable when it was all soldered together. After it got super hot on the battery we decided to desolder everything to figure out what causing the problem. That's when we discovered that the PowerBoost might be the problem.

Can you post a photo of board showing both sides.

Just noticed this in your first photo. Looks like there is a component missing from the top of the board. Do you know if that could have somehow been knocked off during the build?

That's totally possible! I totally missed that. I guess I will have to order another PowerBoost! Thanks for the help!!

Sorry that happened. Be sure to check the new one before you put it in the project and make sure it's functional. That way you'll know it arrived OK and any subsequent problems will be a result of some aspect of the build. Just a simple sanity check that will help with any trouble shooting, esp. when doing a more complex build like a Pi GRRL. Good luck and hope you get it working!
