LimeSDR mini 2.0

Sprzętowa platforma transceivera SDR LimeSDR mini 2.0

LimeSDR mini 2.0 to sprzętowa podstawa typu open source do stworzenia transceivera SDR lub wykorzystania jako odbiornik szerokopasmowy SDR. Może ona posłużyć do własnych konstrukcji, zarówno autonomicznych (stand-alone), jak i sterowanych z poziomu komputera czy nawet tabletu lub telefonu. Zakres pracy 10MHz-3,5Ghz.
