− | *11-26-08 : NEEDS U39 replaced
| |
− | *11-25-08: Not operational
| |
− | *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.
| |
− | *11-8-08 : requires external device to hold it on...

− | *11-26-08 : operational
| |
− | *11-26-08 : R102 missing this is a pull up on the real time clock
| |
− | *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

− |
| |
− | * 11-19-08 : Applied 3.3V to ISP header and SC booted.
| |

| |
− |
| |
− | * 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

| |
− | *11-19-08 : Needs battery measurement modification.
