| Jan 6, 2015 at 22:34 | comment | added | Alex Wayne | Are you saying that using a fully charged LiPo at 4.2V and then using 5V logic form the programmer can cause damage to the chip? If so, I guess that's a good reason to connect the 5V power pin from the programmer to the chip, to bring the supply voltage up to match the logic voltage? | |
