Alchitry Au V2 FPGA Development Board (Xilinx Artix 7) - แท้จาก Sparkfun, USA

The Alchitry Au V2 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. 

The Artix 7 FPGA requires a free license for Vivado. Click here for instructions on installing it.

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!
