Feather 32u4 RFM95 LoRa Radio - Product ID 3078

by mathieusnt2 on Thu Aug 22, 2019 3:31 am

Hi,
We ordered for 270 units of Adafruit Feather 32u4 RFM95 LoRa Radio - Product ID 3078 but some of them were damaged.
Indeed, when we connected the Feather in USB, only one red constant LED was visible on it and no communication was possible with ARDUINO.
Thus, could you send us more units for next delivery please?
Thank you.

We're going to need more information to authorize any kind of replacements.

First, verify your USB cables by using them to connect some other known-working device to a computer. There's a plague of charge-only cables out there with USB connectors at both ends but no wires for the data signals.

Just swapping cables has no diagnostic value. You need the true positive of a working USB connection to rule out the false negative of a charge-only cable.

We tested in same conditions for all 270 units and 3 was damaged.
So the problem comes from Feather.
We do not have more choice to delete them from our preparation
Thank you.

If you used the same USB cable for all of the units, we can assume it's good.

For the 3 units that failed your tests, what were the specific failures? Did they fail to make USB connections, or was there some other problem?

Honnestly, they didn't remember if other problems occur
