So, we heard you like SAOs. How about some SAOs for your SAO? That’s exactly what’s going on here with [davedarko]’s SAOAO — introducing the Supercon Add-On Add-On standard, which is inspired by another minibadge standard by [lukejenkins]. At most, an SAOAO is 19×19 mm and features a 1.27 mm 3-pin header. As [davedarko] says, no pressure to do I²C, just bring the vibes.
All SAOAOs use the Yo Dawg SAO baseplate, which has room for three SAOAOs. Because six pins is often too many to make a few LEDs light up, the SAOAO standard uses a mere three pins. Not only are SAOAOs easier to route, the pins can’t even be mirrored accidentally because VCC is in the middle, and both outside pins are grounds.
Want to get your hands on some of these bad boys? [davedarko] is bringing 100 Yo Dawg SAO baseplates and 200 SAOAOs to Supercon. But if you want to make your own, you are more than welcome to do so.
I am waiting for someone to abuse the standard and come up with a power-pulsing based communication protocol. Simplified SAO over SAOSAO? SSoS?
I believe 1wire already has a standard for this, you just need a capacitor.
or something like the modern model trains have these days
DCC is neat but runs at 12 volts.
shitty addon addon rather, no?
no – I made it, I can name it.
Ok technically I call it simple add-on myself, but we can all agree that it’s shitty add-on compatible at least.
It’s SAOs all the way down…
