The Alchitry Au is the "gold" standard for FPGA development boards and it's possibly one of the strongest boards of its type on the market. FPGAs, or Field-Programmable Gate Arrays, are an advanced development board type for engineers and hobbyists alike to experience the next step in programming with electronics. The Au continues the trend of more affordable and increasingly powerful FPGA boards arriving each year. This board is a fantastic starting point into the world of FPGAs and the heart of your next project. Finally, now that this board is built by SparkFun, we added a Qwiic connector for easy I2C integration!

The Alchitry Au features a Xilinx Artix 7 XC7A35T-1C FPGA with over 33,000 logic cells and 256MB of DDR3 RAM. The Au offers 102 3.3V logic level IO pins, 20 of which can be switched to 1.8V; Nine differential analog inputs; Eight general purpose LEDs; a 100MHz on-board clock that can be manipulated internally by the FPGA; a USB-C connector to configure and power the board; and a USB to serial interface for data transfer. To make getting started even easier, all Alchitry boards have full Lucid support, a built in library of useful components to use in your project, and a debugger!

By adding stackable expansion boards similar to shields or HATs called "Elements," the Alchitry Au is able to expand its own hardware capabilities by adding prototyping spaces, buttons, LEDs, and more!
