JTAG adapter board 04.pcb

LimeSDR 'JTAG' adapter for connecting SPI bus to Arduino 3.3v Due. The pinout connectors on the LimeSDR are extremely small and almost impossible to get a reliable connection with 'bare wires'. The only sure way is to get this PCB made.

Here I attempted to re-transmit received frequencies at centre frequency 806MHz with a bandwidth of 30MHz. (Band 20 base Tx LTE). Although I got a nice Rx spectrum in the LimeSuite FFT, my second SDR rig failed to notice successful transmission :(
