Use the new Alchitry V2 boards with your old V1 add-on boards with this V2 -> V1 adapter.

It has the new style connectors on the bottom and the old style on the top.

It is not 100% compatible with V1. The V2 headers no longer expose the 100MHz clock signal or UART Tx and Rx signals. The actual pinout is also different but global clock inputs for the Au route to the same spots as well as analog and dual voltage pins.

Dual voltage pins are also now 2.5V instead of 1.8V.

This board is currently in the prototype stage.
