fix beeper interference with sma
Bdale Garbee [Mon, 18 Apr 2011 08:27:59 +0000 (02:27 -0600)]
resolve switch / sma interference issue by moving switch 50 mils farther out
Bdale Garbee [Mon, 18 Apr 2011 08:18:53 +0000 (02:18 -0600)]
route complete, drc clean, added the usual silkscreen elements
Bdale Garbee [Sat, 16 Apr 2011 00:27:33 +0000 (18:27 -0600)]
pull ground plane back away from BT antenna, work more on placement
Bdale Garbee [Thu, 14 Apr 2011 02:17:25 +0000 (19:17 -0700)]
adjust placement to account for pcb dimension reduction
Bdale Garbee [Thu, 14 Apr 2011 02:07:17 +0000 (19:07 -0700)]

working on placement
Bdale Garbee [Tue, 12 Apr 2011 07:10:29 +0000 (00:10 -0700)]
connect both VDD pins on BT module, add a second bypass cap by it
Bdale Garbee [Tue, 12 Apr 2011 07:07:44 +0000 (00:07 -0700)]
add beeper
Bdale Garbee [Sun, 10 Apr 2011 20:30:41 +0000 (13:30 -0700)]
pcb syncronized with schematic, all parts on board but not placed yet
Bdale Garbee [Sun, 10 Apr 2011 20:07:16 +0000 (13:07 -0700)]
move the "ground plane" to the "top" of the board since we want all the SMT
parts in this design "down" towards the bottom of the box and all the through
hole "up" towards the lid. this seems much easier than trying to invert the
board outline.
Bdale Garbee [Sun, 10 Apr 2011 20:00:51 +0000 (13:00 -0700)]
fix hole size in schematic to match 1551K mounting holes
Bdale Garbee [Sun, 10 Apr 2011 19:49:25 +0000 (12:49 -0700)]
lock the outline, the bottom poly and boundary vestigal lines, and the holes
clear out the rest of the parts
Bdale Garbee [Sun, 10 Apr 2011 19:39:41 +0000 (12:39 -0700)]
expand bottom poly to full board size, then clone outline into bottom layer
as a 1-mil-wide vestigal line to use line clearance to shape the bottom side
ground plane to uniformly cover inside the board outline with some margin
Bdale Garbee [Sun, 10 Apr 2011 19:32:43 +0000 (12:32 -0700)]
holes moved to the right places for maximum size 1551K board outline
Bdale Garbee [Sun, 10 Apr 2011 19:16:35 +0000 (12:16 -0700)]
outline now matches Hammond max PCB size for 1551K box
Bdale Garbee [Sat, 9 Apr 2011 20:43:31 +0000 (13:43 -0700)]
Outline and hole positions right for board that is 2mm smaller in both
axes than max for 1551K box. Not satisfied, though, as the PCB mounting
holes land very close to the edge of the board this way. Must re-evaluate
outline before proceeding!
Bdale Garbee [Fri, 8 Apr 2011 18:40:07 +0000 (11:40 -0700)]
update to use freshly generated Rayson module footprint

loss the vdd_usb connection on the BT chip
Bdale Garbee [Tue, 5 Apr 2011 04:27:48 +0000 (00:27 -0400)]

Bdale Garbee [Tue, 5 Apr 2011 03:18:31 +0000 (23:18 -0400)]
hook up pin on BT widget that would allow us to reset its serial port
Bdale Garbee [Tue, 5 Apr 2011 02:59:44 +0000 (22:59 -0400)]
replace BTM182 datasheet with fresher copy from the company themselves
Bdale Garbee [Tue, 5 Apr 2011 02:58:57 +0000 (22:58 -0400)]
symbols needed for schematic
Bdale Garbee [Sun, 3 Apr 2011 19:01:06 +0000 (13:01 -0600)]
