We'll survive. I have a 3.6, two 4.0's and a 4.1 I can keep going with the current projects on the 3.6 but will design new base boards for the 4.0 and 4.1. Getting PCBs fabricated is no longer the expensive nightmare...
I got careless with my outputs and connected a power amp to the headphone output on my Teensy audio board, which killed my Teensy 3.6. Yeah, I know. I feel a right idiot.
I have a spare 3.6 so development hasn't...
