This adapter lets you use new Alchitry V2 boards with older Alchitry V1 add-on boards. It is designed as a bridge between the updated V2 connector layout and the original V1-style add-on ecosystem.

The board has the new style connectors on the bottom for the V2 board, and the old style connectors on the top for V1 add-on boards. A schematic is provided in the documentation for checking connections before you build around it.

Please note that this adapter is not a 100% V1 compatibility layer. The V2 headers no longer expose some signals, the actual pinout is different, and the dual-voltage pins have changed voltage.

Specifications:

Bottom connectors: New style connectors
Top connectors: Old style connectors
Compatibility: Use new Alchitry V2 boards with old V1 add-on boards
V1 compatibility: Not 100% compatible with V1
V2 header signal availability: 100MHz clock signal is no longer exposed
V2 header signal availability: UART Tx and Rx signals are no longer exposed
Pinout: The actual pinout is different
Au global clock inputs: Route to the same spots
Analogue pins: Route to the same spots
Dual voltage pins: Route to the same spots
Dual voltage pin level: Now 2.5V instead of 1.8V
Documentation: Schematic

Jargon buster

Plain-language definitions for the technical terms used above.

Headers: Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
UART: UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
