FireAnt: Low-cost, thumb-sized, breadboard-friendly FPGA development board (including schematics, source code, etc.) for manufacturers and hardware designers

FireAnt is the first third-party development board in the Efinix Trion product family. It provides an easy-to-use development platform for FPGA manufacturers and enthusiasts. Powered by Efinix Trion T8, FireAnt requires only a PC and requires no additional components. Breadboard-friendly design allows applications to be quickly deployed using sensors, peripherals or other interfaces. It is the perfect solution for manufacturers prototyping their projects or for digital design students to quickly learn FPGA development using the new Efinix platform. The power/performance/size advantages of Trion T8 FPGA also make it ideal for edge IoT applications.
