This L5973D module can accept input voltage up to 20 V. The 5 V output is used as a power supply for Rasberry Pi 3 B+ board. The 12 V input is connected via XT60 socket and passed to L5973D module and to MikroTik devices via PoE header. L5973D – step-down voltage converter (12 → 5 V).I bought a loudspeaker used in Dell E5470 laptop, which fits into the aluminium case together with other components and provides sound feedback (new network detection, no GNSS fix loss, connection problems, etc). This is a nice and cheap mono audio power amplifier module. I soldered an external CR2032 battery which should last many years of continuous operation. The long-term accuracy seems to be even better than specified. It has configurable parameters, including update rate – up to 10 Hz.ĭS3231SN is a great TXCO real-time clock IC, with 2 ppm accuracy specified within 0☌ to +40☌ temperature range. It is connected directly to Raspberry PI via UART (115200). This is a very reliable GNSS receiver (GPS, Galileo, GLONASS and BeiDou). This build is based on Raspberry PI 3 B+ with… New version (2021)ģ × OmniTik and 2 × SXT SA5 ac with a new Raspberry PI 3 B+ build is up and running! All received packets are forwarded to the Raspberry PI, where beacons and probe responses are analysed. Using the passive sniffer tool in MikroTik RouterOS software, each device performs TZSP streaming. The user interface is available via VNC on a mobile phone or laptop. The Raspberry PI computer runs Arch Linux ARM operating system with multiple instances of the MTscan software. Its purpose is to provide an additional source for network identification in my Wi-Fi DXing project. It is based on Raspberry PI computer installed inside a car and multiple MikroTik devices with built-in dual-polarization antennas. I built an advanced wardriving system for Wi-Fi network logging dedicated for the 5 GHz radio band. (…) Wardrivers use a Wi-Fi-equipped device together with a GPS device to record the location of wireless networks. Wardriving is the act of searching for Wi-Fi wireless networks, usually from a moving vehicle, using a laptop or smartphone.
