Editing BeagleBone


''(FIXME: a few words here about the BeagleBone ...)''

The '''BeagleBoard''' and the '''BeagleBone''' are [[motherboards that run Linux | open-hardware boards that run Linux]] based on Texas Instruments system-on-a-chip.

The BeagleBone is based on the Texas Instruments AM3358/9 system-on-a-chip which includes a ARM Cortex-A8 CPU.

The BeagleBoard is based on a Texas Instruments OMAP3530 system-on-a-chip, which in addition to the ARM Cortex-A8 CPU also includes a TMS320C64x+ DSP.

They are supported by the Texas Instruments company.

== tips for designing a new BeagleBone cape ==

''(If you've designed a cape, please add to this page a few tips that you wish you had known earlier)''

A few OpenCircuits members have designed BeagleBone capes.

You may want to throw together a quick proto board
before spinning a custom PCB.

When designing a cape, you may want to look at the capes that have already been designed -- see "lists of existing capes" below.
Perhaps some pre-existing cape (or a stack of capes) is close enough that you can buy one,
cut out stuff you don't want and hack in a couple more things,
then confirm that the new circuit will work,
with less effort than making a prototype completely from scratch.

When designing a cape, consider perhaps making the outline small enough
that the stack fits in some off-the-shelf
[[Enclosures#BeagleBone enclosure]].

Alas, many designers assume *their* cape is going to be on top,
which makes such capes useless to people that need to have some *other* cape on top.
Therefore, try to design your cape so it works when plugged into the middle of a stack.

=== stacking connectors ===

''(FIXME: isn't there some other OpenCircuits page that discusses stacking connectors? Link to it here.)''

BeagleBone capes need to have 23x2 position gold plated 0.1" pitch stacking connectors.

http://blog.machinekit.io/2013/06/using-bebopr-with-beaglebone-black.html
lists one source of stacking connectors for BeagleBone.

Perhaps using several of these connectors side-by-side and end-to-end would be adequate?:

Is this connector adequate?:
"Samtec SSQ-123-03-G-D" available from DigiKey

Major League SSHQ-123-D-06-G-LF
Major League SSHQ-123-D-08-G-LF
Major League SSHQ-123-D-10-G-LF
or etc.
according to p. 101 of the
BeagleBone Black System Reference Manual (SRM).
