feather 32u4 RFM95 LoRa no communication
I purchased 40 of these feathers in December. When I went to upload to them some were not being recognized by my computer. Double checked device manager, arduino, updated all my board and library info, restarted and retried. I could not get them to connect. I noticed the red LED does not flash when I plug them in. This is happening to 14 of the 40 I got. The rest operate just fine.

Okay, we might be replacing 14 units for you.
Do you have the original pink ziplocks they came in? There can be useful batch numbers on there. Maybe there was a batch that did not get a bootloader or had a assembly issue?
Did you observe any physical differences between a working and non-working board?
Do any LEDs come on with the non-working boards? Does double-reset have any effect to enter bootloader mode?

I do not see a physical difference between the ones that work and do not work. I do have the packaging that they came in. They are red seal bags, not the zip-lock bags. I had to put a small cut to test each board. The two bar codes have the codes P3078 and W14712-C under all of them. They still have the yellow LED blink once when you plug them in, but then nothing happens afterwards. The reset has no effect.
