Description:

If you are not needing a lot of power to start your FPGA adventure, or are looking for a more economical option, the Alchitry Cu FPGA Development Board might be the perfect option for you! The Alchitry Cu is a "lighter" FPGA version than the Alchitry Au but still offers something completely unique. 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 Cu truly exemplifies 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 Cu uses the Lattice iCE40 HX FPGA with 7680 logic cells and is supported by the open source tool chain Project IceStorm. The Cu possesses 79 IO pins with 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.

Notice: Lattice offers free licenses to hobbyists, enthusiasts, community educators & start-up companies. If this describes you, please contact them to register for a free iCEcube2 license with subject “New iCEcube2 License Request”.

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