My Espruino died today. When plugging in the USB or battery it did not seem to work. Trying to enter boot loader mode did not work and no flickering from the LED's. I measured voltage levels on batt and 3.3 with USB plugged in. Bat was 4.9 volts 3.3pin reads 0.7 volts. If I connected a 3.3 volt power source to the 3.3v pin next to bat the espruino works and I am able to send commands from the serial console via USB. Is there a fuse on the board or which component number is the voltage regulator?
