JTAG adapter board 04.pcbLimeSDR '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.pcb - 88.00 kB - 10/18/2017 at 12:07 |

Cell Phone 4G LTE Repeater / Booster / Femtocell
An outside pole mounted aerial picks up 4G signals which are then filtered, amplified and re-transmitted through a second inside aerial.
