I had my VIN & GND connected to 10V and moteino was working fine. Then I forgot that external power was connected and then connected the USB to my mac through the FTDI board. My mac rebooted and the moteino was flaky (intermittent led flash) and now it does not seem to flash (led I mean) at all.
I am not able to get the serial port to show up on my mac anymore. I thought I busted my USB port on my macbook, but I am able to read USB drives just fine, so I do not think it is damaged.. Could it be the that FTDI board also got damaged? Should I try to get another one?
Did something similar once, most probably the FTDI is the damaged part. Try another one.
Yes the FTDI is probably damaged.
