100-8A (BF2)
- 12-15-08 : force power on ECO & battery voltage ECO
- 12-14-08 : scan of SC ADCs show that they're out of range.
- 12-14-08 : applied power, MC is now operational
- 12-12-08 : MC switching regulator replaced???
- 12-11-08 : verified that MC switchers have Vsup. Applied SC 3.3V to MC 3.3V, ~80mA flowed, and the MC booted.
- Motor control NOT operational (State operational)
TODO
- needs testing
110-006
- 12-10-08 : bench top offsets (3250, 3200) with power board #110-005
- 12-04-08 : Installed into PROTO2
- 12-04-08 : Board ran all night tests Good!
- 12-04-08 : started Upd_test_pattern_112608a with PB 110-008
- 12-04-08 : added force power on ECO and verified that power board lights
- 12-03-08 : U39 has been replaced with LT3470AEDDB#PBF
- 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

110-007
- 12-17-08 : has trouble starting.
- 12-15-08 : Installed R192 replace C137, C146 with 0.0001uf
- 12-11-08 : current offsets caused by missing R192. Also verify filter caps - C137, C146 (remove or replace)
- 12-10-08 : offsets (3254, 22197) mode 7adc reads (2252, 3440)
- 11-30-08 : 1st current sensor has large offset
- 11-30-08 : appears that solder on a 1210 cap was making case contact. This was corrected, and tape is being put on the case surface.
- 11-28-08 : installed into #2, appears to have trouble turning on - staying on. Appears to be caused by rework and raised components shorting to case.
- 11-28-08 : Ran 36 hrs test with Upd_pcb#110-005
- 11-26-08 : operational
- 11-26-08 : R192 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 system 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

110-008
- 12-14-08 : powered and no motor controller LED
- 12-12-08 : switching regulator replaced??
- 12-11-08 : verified that MC switchers have Vsup. Applied SC 3.3V to MC 3.3V, ~100mA flowed, and the MC booted.
- 12-10-08 : MC is unpowered. Need to replace MC 3.3V switcher?
- 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

==110-009 == (BF1)
- 12-22-08 : Replaced cap C142 & ECO battery voltage done
- 12-12-08 : robert states that there is mechanical damage to the PCB and some of the encoder decoders.
- 12-12-08 : still running in morning
- 12-11-08 : ran Upd_test_pattern_112608a with PB 110-008 overnight
- 12-11-08 : Added jumper wire from R68 to U16.6. Encoder now works.
- 12-11-08 : No QEI signal MC pic pins 11 and 13. Look back at U16,17. No signal on U16.6
- 12-10-08 : appears that board is unable to read what appears to be a working encoder.
- 12-10-08 : With FET 110-008, mode 7 offset (3128,3153) adc (2244, 2252)
- 12-04-08 : was operational in PROTO2 since Monday. Worked well. Removed to add ECO
- 11-29-08 : operational - tested with PB 100-002
- 11-26-08 : operational, but missing CAP in middle row (C142?)
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.
