Yes, this was all considered and the template follows that, thanks.James Adams wrote: make sure they are isolated (NOT electrically connected to GND or any other net) and preferably non plated (non plated holes can generally be drilled to tighter tolerances). Basically make them the same as on a B+ and you're good.
In Eagle you can switch between metric and imperial on the fly. During this template creation I switched this probably 5 or 6 times (to metric for outline and to imperial for components placement).panik wrote:Since the spec is defined in metric and Eagle works with imperial
Displayed offset might occur due to some rounding. If you switch to metric and check the dimensions, they should match.panik wrote:the header in my version is 0.0005" off compared to yours.
Optical illusion...panik wrote:I also noticed the rounded corners on the display flex cutout in your version are a bit too big. Spec says R=2mm, and I think yours are 3 or 3.5?
Ok, I've updated the template (URL of the zip is the same, as listed in my initial message).panik wrote:Just a heads-up; as it turns out, the "R=2mm" in the drawing is a mistake. It should be "R=1mm"
Really handy, thankyou.I have created a full-blown EAGLE component library which contains (among other boards & shapes) the RasPi model B+ HAT.
Trace width is just one parameter. What might prevent autorouting success is clearance - check values of these parameters.dickon wrote:I can't seem to get Eagle to autoroute from the top row of pins to anything else I place on the board. What am I doing wrong? I'm assuming that it thinks the tolerances are too tight, but even making the nets thinner doesn't seem to help.
You can make a serious design, means put components on a schematics page, wire them up, etc. Then change to PCB and place/route them.JohnKoz wrote:Hi, sorry for the remedial question, I'm new to PCB board design.
I downloaded the HAT template that FlyFish shared, and added the component from raspberrypi_bastelstube_v13.
It is a single image of a hat board with a connector.
How do I drop components on the board surface and align them to this template, do I just align by site over the image, then remove the image later? Do I add my own connector, or route lan's to the existing image?
(I attached a screenshot of an example hat template)
the .zip-file in the first post contains two sets of .sch+brd for a HAT with and without slots. Use them as a template, adding components to the schematics page. The GPIO connector is placed correctly already.JohnKoz wrote:My apologies to readers of this thread, I confused 2 links. One was the link provided in this thread, which was to an actual board and schematic.
The other was actually the subject of my question, which was not related to this thread. My question was actually regarding the following library: http://eagle.autodesk.com/eagle/download/254, specifically the RASPI_BOARD_B+HAT component. That is the image which appears in my question. As it is not a brd/sch file, but simply a component, I was asking how it was intended to be used.
Again, my sincere apologies to @aBUGSworstnightmare and other readers of this thread.
I've pursued my question elsewhere, as to not ware out my welcome on this Raspberry Pi forum. I will post my answer here for completeness when I figure it out.
