This video shows a Flip32 flight controller ($15 from re readytoflyquads.com) onboard a min 250 quadcopter, sending IMU attitude telemetry (pitch, roll, yaw) to my laptop via a Bluesmirf Bluetooth module ($35 from sparkfun.com). The Bluesmirf connects to the Flip32's UART via a four-pin jumper cable, also from Sparkfun ($.095).…Continue

In my last post I showed a Flip32 flight controller talking to a PX4Flow unit using the I^2C protocol. Once that was working, I wanted to mount the PX4Flow to a vehicle and make a more permanent cable connection.
I added a few lines of code to the Baseflight firmware to get optical-flow velocities and sonar altitude from a PX4Flow unit connected to a Flip32 flight controller over I^2C. In the video you can see the readout on the laptop showing the computed X/Y flow velocities (meters per second) and distance (meters), multiplied by…Continue
