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 SparkFun builds this board, 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 256 MB of DDR3 RAM. The Au offers 102 3.3 V logic level IO pins, 20 of which can be switched to 1.8 V; Nine differential analogue inputs; Eight general-purpose LEDs; a 100 MHz 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!
