todo
- install R102
ECOs
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
