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?: https://www.sparkfun.com/search/results?term=stacking+connector

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). and the BOM at http://boardzoo.com/index.php/beaglebone-black/extended-proto-cape.html Available from: stacking connector at Future Electronics.
