- Verify operation of RE40 encoder new motor test stand. Appears to not be working
- Rewire 8-cell A123 battery pack to 7cell.
- programming cable in PCB repair box is bad.
- Build Vclamp8 with NEW PFET and 35w resistor
- Ship 1 Vclamp8 to UPD
CEB todo
- current measurement PCB (with Y voltage measure)
- encoder breakout boards
- SG breakout boards
State / Motor Controller
110-006
- 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...
- 10-6-08 : installed in UP#3
TODO
- replace U39
ECOs
110-007
- 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
- 10-5-08 : installed in UP#3, made battery measurement ECO
TODO
- install R102
ECOs
110-008
110-009 (BF1)
- 11-26-08 : operational
- 11-20-08 : Needs the 24 pin flex connect to be replaced. (replaced 11-25-08)
- 11-19-08 : Needs battery measurement modification.
- 11-8-08 : has jumper wire to turn self on, but wouldn't boot until IMU attached. After first power, remove IMU and works fine.
TODO
- needs battery voltage ECO
Power Board
110-004
- 11-26-08 : benched tested for 3 days.
- 11-26-08 : has 2.0 ohm gate drive
- 11-26-08 : has 225W TVS on bypass caps.
TODO
- needs gate drive ECO
