Ready for Crowdfunding

After many months of preparation, the team here at Radiona is ready to launch our crowdfunding campaign for the ULX3S FPGA with ESP32. Hackaday described ULX3S as creating "the Year of the Hacker FPGA," and we are finally ready to make that prediction a reality. Many people have worked to prepare this board – and the sample code that highlights its potential – for distribution to makers and hobbyists worldwide. We believe this is one of the best developer boards ever designed, as it incorporates a vast array of features and capabilities into one relatively small and reasonably priced package.
