Feeder programming steps don't mention setting VCC jumper to 3v3 #114

Moving this issue over from the feeder source repo. Original issue by @KC0D can be found here.

The instructions for updating the feeder firmware shows the use of an Arduino type USB to serial adapter with 6 pins. The adapter like the one you have shown, has a jumper near the pins that sets the output voltage and output signal levels to 3.3V or 5V.

The instructions should warn users to set the jumper to 3.3V before inserting it into the board. Failure to do this could blow up the processor chip if it is set to output 5V image
