Universal Qi Wireless Charging Transmitter Issues

Post by ad135 »

Hi all,

I just ordered 10 of the wireless chargers at the following link: https://www.adafruit.com/product/2162

These look a bit different on the PCB board and the coil ferrite backing is different than the old units. They do not seem to be working correctly. They will briefly light the blue LED when the coil recognizes a device to be charged, then they will blink red 2-3 seconds later. I have some new in box units of the old design that work fine using the same USB and the same device to be charged. Any ideas to solve the issue or is this a known problem with the parts substituted?

In the photo: a new unit on the left, and a new old stock unit on the right.

Thanks!

Just to double check - all 10 from recent order are behaving the same way?

we can't get any of the previous version due to the silicon shortage. if the new ones dont work for you, you can return them for a refund but they are 'plug and play' - there's no changes or documentation

Okay unfortunately these aren't working in my build that utilizes the old chargers. I would like to proceed with the return.
