Feather 32u4 w/ LoRa No USB Connection

Post by derekbarnhart »

Hello,
Today I received a Feather 32u4 Lora Module and I have not been able to get any of my machines to recognize/detect it as a USB device.

What I have tried:
- Installed Arduino IDE board support for adafruit boards
- confirmed the cable I am using is a data usb cable by using it to connect another device successfully
- confirmed no change in the output of `ls /dev/tty*` after plugging in to both a Mac M1 and Raspberry Pi
- pressed reset on the board after plugging the usb cable in (this had no visible effect on the board leds)

Observations:
The led near the charger connector never lights up.
The CHG led flashes once momentarily when connecting to usb without a battery or stays lit if the battery is plugged in.

There are 2 barcodes on the packaging. P3078 and W14712-C are the labels under the barcodes on the packaging incase that helps traceability to a batch.

Should I attempt burning a new bootloader or would it be better to just get a replacement board?

Thanks

Well, you've done all the appropriate troubleshooting, so you're getting a new one either way. ;-)

Trying to burn a new bootloader on the one you have can't hurt, and if it works, cool. It still counts as a production failure on our end, and warrants replacment.

Send a note containing a link to this page and your order number to support@adafruit.com. The folks there will get you a replacement.

Unsurprisingly, burning the bootloader failed. Thank you for your help!
