Routed USB circuit and most of AVR on power board

Routed most of the signals connecting the USB port, FTDI chip, and AVR.

1a5559b0 11/05/2011 10:46 PM Abraham Levkoy

Changed USB port drill holes back to spec

Looked at mini USB port with Dan. Observed that corner drill holes are
supposed to be multiple drills right next to eachother. Decided to
change holes back to specfied radius and ignore long hole for now.

30d533fe 11/05/2011 07:05 PM Abraham Levkoy

Preliminary power board placement complete

Placed all parts on power test board in what I believe will be their
approximate final locations. No routing done yet. Board probably won't
get bigger, because I left room to grow.

9180be39 11/05/2011 06:17 PM Abraham Levkoy

Partial placement of power board

Placed AVR, FTDI chip, and USB port on power test board, along with
their accessory components. They are probably pretty close to their
final resting place but may move a little bit later.

00c7cdb1 11/05/2011 05:29 PM Abraham Levkoy

Changed IO voltage for FTDI IC on power board

Changed VCCIO input for FTDI chip on power test board from USB_VCC to
internally generated 3.3V signal. This should have no power effects, but
Kevin suggests that it may make the chip behave a litte bit nicer (not...

344a6bf3 11/05/2011 04:00 PM Abraham Levkoy

Fixed ERC errors from unconnected wires

Some wires created in the previous few commits were not actually
connected to the pins they ended at. I fixed them.

13790121 11/05/2011 03:20 PM Julian Binder

Changed Schematic

Tied USB Shield pin to ground

168d92e6 11/05/2011 03:09 PM Julian Binder

Added a missing junction

90591b4b 11/04/2011 06:39 PM Abraham Levkoy

Undo accidental extraction of zipped Gerber files

Restored compressed Gerber files from commit
6bcd5b932bde03c525653653638fddd5251a5705 after they were accidently
uncompressed (and the ZIP files deleted) in commit
072e099013d16c67deffe4ef7299f8c05c2dd6c2. Deleted directories created...

33c4366f 11/04/2011 06:10 PM Abraham Levkoy

Updated DS2786 footprint in kwoo library

Updated package footprint for DS2786 in kwoo.lbr based on recommended
land placement in datasheet for DFN10 package. DS2786's datasheet lists
TDFN10 as its package type but doesn't give placement guidance or a
useful package description. Unable to find a datasheet for TDFN10, but...

51b65a87 11/04/2011 05:09 PM Abraham Levkoy

Increased mini-USB plug drill hole size

Imported MINI-USB- device from Hirose Connectors library into kwoo
library. In UX60-MB-5S8 package, increased drill hole size on corner
pins from .8 mm to .9 mm. I did not drill out the original too-small
holes on Scoutfly, so I don't know whether this is sufficient or not....

fc0c916c 11/04/2011 03:12 PM Abraham Levkoy

Updated inductor package for power board

Created new package and device in library for MPI4040 inductor to be
used in power test board. Updated part on power test board.

109296da 11/04/2011 04:10 AM Abraham Levkoy

Fixed GND pad on LT3650 charger IC

LT3650 package in kwoo.lbr had a polygon around a through-hole pad to
approximate a large SMD pad connected by a via directly to the ground
plane. Created a new package that is like this one but has no via, just a
normal SMD pad. Used this package in the power test board, which has no...

4327ce8c 11/04/2011 02:57 AM Abraham Levkoy

Updated design rules for power board

Updated design rules for power board to match DorkbotPDX specifications.
This removed some of the DRC errors for the USB port and charger. The
charger still has a couple that may be from inherently illogical
package specification.

a7a07a86 11/03/2011 11:52 PM Abraham Levkoy

Disapproved DRC errors on power board

Disapproved of previously approved DRC errors for power board. They are
apparently legitimate problems that need to be taken care of.

072e0990 11/03/2011 10:32 PM Yuyang Guo

powerboard placed, needs routing

6bcd5b93 11/03/2011 05:28 AM Abraham Levkoy

Fixed gas gauge and charging components

Added extra decoupling capacitor between battery voltage and ground next
to charging circuit to allow board to run with charger but no battery.
Connected system side of gas gauge sense resistor to GND to make all
current returning to battery go through sense resistor. Removed 0 Ohm...

cbe8706d 11/03/2011 03:34 AM Abraham Levkoy

Added missing components around AVR on power board

Added ISP header, pullup resistor for AVR reset line, and decoupling
capacitors for AVR power lines. Connected ISP header to SPI interface on
AVR.

cb409f92 11/03/2011 02:37 AM Abraham Levkoy

Finished USB interface on power board

Added decoupling capacitors to FTDI chip, changed signaling VCC from USB
VCC to AVR VCC so that AVR can signal to FTDI chip. Added USBTX and
USBRX signals between FTDI chip and AVR.

8c16f5aa 11/02/2011 07:15 PM Abraham Levkoy

Started to add USB port to power board

Added USB port and USB-UART converter to power board schematic. I think
the converter has enough hooked up to it to run without burning up, but
it's not hooked up the AVR yet.

107d33d7 11/02/2011 05:10 AM Abraham Levkoy

Shorted GND to BATT_GND in power schematic

Connected GND and BATT_GND to eachother using a 0 Ohm resistor. I want
to keep the signals separate to ease routing, but they need to be
connected to ensure that all of the current that needs to go through the
fuel gauge sense resistor does so.

9f7d5c6f 11/02/2011 04:35 AM Abraham Levkoy

Fixed ERC errors

Added some missing junctions and a missing label. Approved "no value"
warnings for parts for which a value would be nonsensical.

f6a93a04 11/02/2011 03:24 AM Abraham Levkoy

Started making kwoo's recommended changes

Made changes to charging circuit: Connected CLP to VIN on U1. Added
diodes to charge BOOST capacitor from battery and provide current
sensing inductor with outlet if power turns off (don't really understand
how the latter works). Adjusted inductor to 4.7uH after re-calculating...

aa3e7f85 11/01/2011 03:13 AM Abraham Levkoy

Update prefixes and names for two parts

Updated prefixes for DS2786 and MP1702 in kwoo.lbr to U so that Eagle
won't use the default prefix, U$, for them. Also manually updated names
in charging_test.{sch,brd}.

680676e5 10/27/2011 05:03 AM Abraham Levkoy

Added pullup resistors and an LED to power test

Added pullup resistors for I2C connections to power test board. Also
added a diagnostic LED to indicate when the AVR has power. Still
probably needs an ISP header and USB controller/port.

0d19b5ca 10/27/2011 04:20 AM Abraham Levkoy

First draft of power testing circuit schematic

Fleshed out power testing circuit. It is still missing a few things, and
I don't understand every little bit of it, but it probably won't look a
lot different when it's done. Added some passive components on the...

94e948f2 10/26/2011 11:59 PM Abraham Levkoy

Updated charging test circuit from kwoo library

Ran update command in charging_test.sch to update parts from kwoo.lbr.

acbd1e46 10/26/2011 10:27 PM Abraham Levkoy

Updated kwoo.lbr with previous kwoo changes

A few months ago, Kevin sent me a new version of kwoo.lbr. Updated
kwoo.lbr with these changes (using the Eagle update command). Also ran
update in scoutfly.sch. This did not affect the results of erc or drc
for scoutfly.

Added kwoo's standalone charging schematic.

charging_test.sch is a standalone circuit schematic for a prototype to
test the charging circuit that will ultimately go on Scoutfly. kwoo
created it. It uses some new parts, but I don't know that much about it...

b68f4fd7 09/29/2011 10:13 PM Abraham Levkoy

Finished hooking up new gyroscope.

Connected pitch output of gyroscope to AVR and gave pitch an output LPF.
Added optional HPFs to both pitch and yaw outputs. We can just leave the
pads empty if we think they won't be useful.

To route the changes, had to squeeze some other stuff. Moved the AVR...

0075932e 09/17/2011 04:39 AM Abraham Levkoy

Routed new gyroscope.

Routed new gyroscope on board in Eagle.

64958645 09/17/2011 03:53 AM Abraham Levkoy

Swapped gyroscope part in schematic.

Replaced old gyroscope part with new one in schematic. Assuming that
pitch output or amplified outputs are undesired. Not using optional
high-pass filter on output. Have not yet routed connections to gyroscope
on board.

5dbaecb0 09/13/2011 11:06 PM Abraham Levkoy

Flipped FFC connector on PCB.

Flipped FFC connector (part J3) on Scoutfly so that mating side faces
out from edge of board. Rerouted wires connecting to J3 to accomodate
this. Because the connected ports don't line up as well as they used to,
the area below J3 has a lot of roundabout paths and layer switches. I...

d374c1a4 08/15/2011 01:56 AM Abraham Levkoy

Began fixing bugs for Scoutfly fixup.

Made several of the changes listed on wiki page ScoutflyUpdate2011. In
particular:
Removed R4 and connected pin 4 on U$3 directly to VCC.
Connected VREG_EN to VCC with 10 kOhm resistor (new R4).
Changed value of R26 to 100 kOhms....
