LimeSDR Mini Updates: Demonstrations with Universal Radio Hacker, LattePanda, PothosSDR and GNU Radio

Over on their CrowdSupply crowdfunding site LimeSDR have been releasing several short tutorials and demonstrations showing their new LimeSDR Mini in action. The latest update shows a short tutorial on using the LimeSDR Mini together with Universal Radio Hacker (URH) to reverse engineer a 433 MHz remote control

Other previous updates include showing how to use the LimeSDR Mini and Wireshark to analyze WiFi signals, using it with a LattePanda mini computer, creating an FM demodulator in PothosSDR and decoding a 433 MHz keyfob in GNU Radio.
