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.
The LimeSDR Mini is a smaller and cheaper version of their LimeSDR which has slightly reduced specifications. The main changes are the slightly restricted frequency range of 10 MHz – 3.5 GHz, and half the maximum bandwidth at 30.72 MHz. The mini also only has 1×1 TX/RX channels.
Recently the LimeSDR was released for crowdfunding on crowdsupply.com and already has raised $165,000 of it’s $100,000 threshold with 12 days remaining. Currently you can back the project for $139 with shipping expected on Dec 31.
