From the project

HF Software Defined Radio Transceiver that includes ADC and DAC circuits. No soundcard is needed. Board communicates only trough one USB cable.

- 96kHz digital I/Q interface. - more then 80dB dynamic range. - DG8SAQ/PE0FKO/SoftRock control interface. - Open Source firmware (https://github.com/AE9RB/peaberry) - SWD/JTAG port.

ToDo: - Change SMA and USB footprints - Add PA - Implement band switching

Based on: AE9RB Peaberry SDR and RS-HFIQ Transceiver
