    EScooter controller serial sniffing

    Upon setting a more suitable baud rate (9600) I was able to see some changes in the data. I'll try to analyze it but it seems a bit random at the moment. Are there any good resources for UART reverse engineering that I should look at before dumping hours into the top google search results? Thanks.

    EScooter controller serial sniffing

    Dear modders I've been trying to gain control over an eScooter drivetrain to control via arduino and figured out the best option would be to intercept the serial communication between the control up on the handlebars and the motor controller. However, after hooking up a logic analyzer and...

    Why BLDC Kv rating? Why not sine wave frequency?

    Phenomenal explanation, Addy! Thank you very much. This also explains why motors with less windings have higher Kv. Less windings means lower back EMF voltage per RPM and thus higher RPM per Volt. :bolt: Best regards

    Why BLDC Kv rating? Why not sine wave frequency?

    I understand that it means noload rpm per volt from the battery, but I cannot figure out how that really works.. If a common BLDC motor is really just a synchronous AC motor, then why is not the speed of the motor solely dependent on the sinewave frequency from the motor controller? Is there...
