Subject: Re: [beagleboard] beaglebone green wireless is shutdown To: "BeagleBoard" <beagleboard@googlegroups.com> Date: Friday, February 10, 2017, 8:33 PM Thanks for the answer. Today were added two capacitor of .1uF and 10uF in power line to beaglebone. System is testing about 4 hours and works fine (all weekend will be testing) El jueves, 9 de febrero de 2017, 18:38:37 (UTC-3), Gerald escribió:It needs to be steady at 5V. 4V is not going to work very well. You can try adding some bulk capacitance across the connections. Maybe 10uF to 20uF and add a 0.1uF as well..

DC-DC converter is stable at five volts in almost time, but there are some events that looks like this picture. (voltage is under 4 volts.)
