This open-source hardware project was made possible with generous support from
|
|
\textbf{PCBWay}, who sponsored prototype PCB fabrication and assembly for
|
|
DigiRadio. Our sincere thanks and deep gratitude go to the PCBWay team for
|
|
believing in the project and helping bring the first boards to life.\par}
