What is SDRstickTM ?

SDRstickTM is a small, low-power SDR built in a narrow strip or "stick" form-factor. The initial three receiver boards (BeRadio, UDPSDR-HF1 and UDPSDR-HF2) are designed to be used with the BeMicro SDK FPGA development board to make a complete receiver. The companion transmitter (UDPSDR-TX2) plugs into UDPSDR-HF2 to make a complete SDRstickTM transceiver.

NEW!  UDPSDR-TX2 User's Manual now available! (7 August 2014)
UDPSDR-TX2 Transmitter and HSMCMEC-AD1 Adapter boards now available (7 August 2014)
