I am an engineer and I do flight controllers. Let me share some of my knowledge with you. Today let's talk about which buses modern flight controllers like Betaflight, Ardupilot, and INAV use. Pros and cons of each one and what kind of devices we connect to every one of them: UART, SPI, I2C and CAN bus!
