Made changes that Abe recommended:Fixed SHDN pin connection.Changed inverter voltage level from 5V to 3.3V.Modified PB Controller to have value displayed.TODO: Address concerns about shutdown timing and switch power loss.
Added a new push button controller circuit. Uses new IC instead of solid state machine because there was no room for solid state machine circuit. Preformed changes that Abe recommended. Routed new circuits. Board should be ready to send back out to kwoo.
Added new switching power supply for 5V and 3.3V supplies. Routed board to include these, and switch.
Added packages to kwoo for diode, dd2pak for switching regulator and switch. Working on schematic for the new power system using switching regulator.
Changed center ground pad for DS2786 and LT3650
Changed ground pads for packages 10MSOP and 12TDFN to have through-holepads on the bottom instead of SMD pads. Updated power test board to usethe new DS2786. Drew a polygon of BATT_GND around center pad. Not sure...
Changed USB port drill holes back to spec
Looked at mini USB port with Dan. Observed that corner drill holes aresupposed to be multiple drills right next to eachother. Decided tochange holes back to specfied radius and ignore long hole for now.
Updated DS2786 footprint in kwoo library
Updated package footprint for DS2786 in kwoo.lbr based on recommendedland placement in datasheet for DFN10 package. DS2786's datasheet listsTDFN10 as its package type but doesn't give placement guidance or auseful package description. Unable to find a datasheet for TDFN10, but...
Increased mini-USB plug drill hole size
Imported MINI-USB- device from Hirose Connectors library into kwoolibrary. In UX60-MB-5S8 package, increased drill hole size on cornerpins from .8 mm to .9 mm. I did not drill out the original too-smallholes on Scoutfly, so I don't know whether this is sufficient or not....
Updated inductor package for power board
Created new package and device in library for MPI4040 inductor to beused in power test board. Updated part on power test board.
Fixed GND pad on LT3650 charger IC
LT3650 package in kwoo.lbr had a polygon around a through-hole pad toapproximate a large SMD pad connected by a via directly to the groundplane. Created a new package that is like this one but has no via, just anormal SMD pad. Used this package in the power test board, which has no...
