4 pin EDU PWM out power, red pin2 V in error
Our EDU controller measures 7.2V(to ~8v charged) on both pins 2 & 4.
Pin 2 (red) should be +5v
Pin 4 (unk color) should be 7.2v
Has any other teams observed this problem ?
I was looking for but find no jumper option
(so servo's could use either unreg or reg)
We could have a fault/failure inside the EDU +5v power distribution.
The middle digital IO pin does properly read +5v
(have been using that until problem is resolved)
anyone know if there are separate +5 regs inside EDU ?
Any ideas what the problem is ? or Do other EDU's have it too ?
Beacons w/7.2v to 8V charged,
using this fault would start our ~2X brighter
8v-1.34/33ohms=.2A
where orig design=5v-1.34/33 =.111A
(note IR LED's were tested, forward V=1.34v at .11A dc)
