  • I ordered twelve of these for our PORPOISE Robotics program in the schools and have started working with 5 of them. 3 are working fine but 2 suddenly stopped working. They don't get recognized by the Arduino IDE. The yellow LED at 13 goes on but there is no way to upload even the blink program. The back of one of them gets very hot, and the back of the other gets medium hot. It doesn't seem to be the IC chip because we swapped out one to test it with a good one. Anybody else having these problems? Has me very concerned. Ideas?
