*11-19-08 : traced MC power.  Found that 3.3V supply only goes 1V - applied 3.3V from prg adpt and MC booted.  Forced R155 high and 5V MC supply worked.
 
*11-19-08 : appears that MC switcher is bad.  Apply 3.3V to ISP, SC boots, but MC does not.

*[[dclamp1]] : passive and digital
*11-26-08 : added R141 to GND ECO (force power on)
 
*11-25-08 : Applied power, not operational
 
*11-19-08 : Applied power, seems to run okay.
 
*11-19-08 : Needs 3.3V to poweron    status : component gets hot.
 
*10-8-08 : received from UPD - tested - seems to be DOA
 
*10-7-08 : received by UPD
 
*10-6-08 : died in ankle while using the battery and under high current load - traced to 3.3V motor controller supply not working.  Was used with power board that has TVS installed on caps, and external TVS were also used.  Died

* 11-26-08 : appears that the motor controller dsPIC is unpowered.
 
 
* 11-19-08 : Rob added GND connection to keep board powered on (either at TP93 or otherside R141)
 
 
* 11-19-08 : Applied 3.3V to ISP header and SC booted.
 
* 11-19-08 : IMU #2 connected, push switch and won't power up
 
 
* 10-5-08 : need to evaluate
 
* 10-4-08 : Removed from UP#3, as randomly powers on at ~10hz due to noise?  possibly damaged due to the pushbutton that WAS attached.
 
* 10-1-08 : Modified for auto-off : requires external signal for power on, has MC battery voltage ECO
