We need a processing unit such as Rockpro64 that supports USB 3.0 (schematic is available online) that connected through USB 3.0 to a FREE SPR SDR board (schematic is available online)
into one board.
Who design this should make sure that the board is working perfectly, The money will be transferred after testing the board.
after the designer prepared the PCB he/she will order the board assembly (cost on me) to our address, we test it and if ok we will release the money. if not no money will be transferred.
After money release, if expect all schematic and PCB files in original format and pdf format.
