I hate to bring this topic up again, ( its been about a year )
Back last year I put two SuperCap rated 1.5f @ 5v in series ( 1.5f 10v ) on EZB's input servo power ( 6v Battery ) to prevent brownouts and its been very successful, and worked well. ( Stopped brownouts ).
But since converting some of InMoov's large scale HS-805BB servo's over to EZ-Robots HDD Servo's I've been getting Brownouts? So I tried various things but still kept getting brownouts.
I then put one of the 1.5f 5v caps on the 3.3v rail of the EZB as you recommended last year, but for some reason it prevents me from connecting to the EZ Builder in Client mode? I've checked and double check and its wired up correctly and as soon as I've removed it, it connects OK! I've carried this out a number of times powering off and back on in-between and get the same results.
I also tried other supercaps, just in-case these two have gone faulty, but still get the same result, regarding the wifi connection.
I measured the 3.3v rail, when the supercap is connected and its still 3.3v, so its not being pulled down at all?
