PowerBoost Shield 500

by Crentist on Mon Jul 20, 2020 12:25 pm

Hi support, I purchased the PowerBoost 500 shield last week (order no.2323676-2625846677) and I'm having issues with getting the battery to power my Arduino (battery also purchased at the same time: Lithium Ion Battery - 3.7v 2000mAh).

No matter what I try, the charge controller seems to be blocking the circuit, I heard there's a fuse on the board somewhere that can trip to protect the battery but I'm unsure which component it is on the board, if someone can clearly identify it for me I'll gladly test it for continuity with my multimeter.

Please post photos showing your soldering to the shield.

I updated the album with view of header pins, my soldering isn't the best but nothing appears to be bridged and multimeter tests that bypass charge controller show they do complete a circuit. https://imgur.com/a/4MOvYw9

Might be worth mentioning that when I first plug in the battery I do get a quick flash from the LED and then everything dies.

If you remove the shield from the Arduino and connect both the battery and USB, which LEDs on the shield light up?

Only the yellow charge light.

Sounds like the boost section is not working for some reason. With no switch installed, it should default to ON as long as there is a battery connected.

Did you purchase this direct from Adafruit, or from a reseller?

OK. Please contact support@adafruit.com with a link to this thread and request a replacement shield.

My new shield came in and I've integrated it into the project, it worked until this morning and now something seems wrong with it.

When the arduino is hooked up direct to the computer and the powerboost shield is installed I need to flip the shield's switch in order for things to work properly, otherwise my output of my attached accelerometer is garbage or non-existent.

Then if I disconnect the arduino's usb cable I'd expect the device to keep receiving power from the shield + 2000mAh batter but the lights on the arduino go off or dim greatly. It's as if the lipo battery isn't sending enough power to the arduino.

Can you suggest some thing I can check? It was all working last night and the battery is fully charged (green light on shield). Even with the arduino appearing dead, I can detect 5v going through my breadboard.

With the battery unplugged, what is the voltage across the battery leads?
With the shield detached from the circuit, do you get a solid 5v on the 5v pin?

With arduino on USB and battery unplugged 0.830v (shield not connected to charge cable) measured on the GND & 5v pin on shield.

Without shield, 5.135v on same pins. What does this mean? There's a short somewhere on the shield?

With the battery unplugged, please measure the voltage on the battery leads.
