  • Hardware SmartPort Inverter using BC547 bipolar transistors

    Hardware SmartPort Inverter using BC547 bipolar transistors

    This post is only a short update for SmartPort inverter for F4 flight controllers. Here is alternative SmartPort inverter circuit using bipolar BC547 instead of unipolar 2N7000. All other aspects of operations are the same like in MOSFET version.

    SmartPort inverter for F4 flight controllers

    While STM32F4 family processors installed in newest flight controllers are superior to STM32F3 (and F1 of course) in terms of raw speed, they are inferior to F3 family in terms of IO handling capabilities. For example, F4 family is not equipped with UART port inverters. There is an S.BUS inverter, but not a SmartPort inverter.…

  • DIY wireless telemetry link for UAV

    Telemetry link between UAV (drone, airplane, boat) and laptop/mobile/ground station device can be very useful. Not only to get current drone position, altitude or battery level, but also, when wireless link provides such a possibility, to update drone parameters in-flight. Some radio links, like OpenLRS provides such a possibility out of the box. They include…
