Quickstart kind of set the new standard,
But once you want to mix and match small add-on boards you run out of Vcc and Vss pins.
Hence I here introduce the new 6P add-on board standard.

The 6 slots on the left have P0 to P23 brought out, good for SPI or any generic I/O.
Pinout: 3.3V, Gnd, IO1, IO2, IO3, IO4
If you want to secure the board down, add a solder glob to the round pad shown, it will also add Vin to the add-on board. (sorry there are no 7P connector)

The 3 slots to the right are for I2C add-on boards.
Pinout: 3.3V, Gnd, SDA, SLK, IO1, Vin

If you need 6-8 GIO, Boards that bridge two connectors will be available.
The board is 100x50mm, this is the connector it uses:

Though a top-mount version is coming out soon, I think the through hole I use will add strength.

    Tony, Nice layout. Looks like a new twist on the old SpinStudio boards. I am actually surprised that someone hasn't made a QuickStart add on board that broke things out in a similar manner. That style of setup would be good for an educational kit where all of the peripheral items are designed in a standard form factor. Just plug n go!

    I will create bare boards in various sizes (Diptrace) so you can put a project together fast and then you order 3 boards from OshPark for around $5 each.
    Here is a Phono Connector Video board, it does not use the left part of the max width.
    Res values takes in account that main board have 100ohm on all pins.
