Troubleshoothing INAV: magnetometer/compass is not working
A magnetometer is a sensor that measures the strength and direction of magnetic fields. In drones, magnetometers are used for navigation to determine geographical direction and allow precise position hold when stationary Your magnetometer/compass is not working with INAV? Is the sensor red in Configurator? You are not the only one… Not only most popular…

Why INAV is not arming
Few weeks ago I’ve decided to shoot more tutorial videos about INAV and this is the first effect of that decission: INAV Troubleshooting: why INAV is not arming Long story short, here is a short list: If you want to know details, here is a video with all relevant information

INAV 1.8 Release Incoming! New Features & Improvements
Next release of INAV, navigation enabled flight controller software, is almost here. INAV 1.8 RC1 has been released just 2 days ago. List of changes is rather long, so here is shortened version with the most important things:

How to connect APM Airspeed Sensor (Pitot Tube) to INAV
Recently released INAV 1.7.2 introduced new hardware support: analog airspeed sensors. I’ve written new but it is new only to INAV. Analog airspeed sensors aka APM Pitot Tubes aka Ardupilot Airspeed Meter and one the market for years. And they are cheap. By cheap, I mean below $30. And until recently they were usable only…

Omnibus F7 Flight Controller
I got my hands on a new STM32 F7 flight controller: Omnibus F7. Before we proceed, small note. I am a huge fan of F7 flight controllers. In a year, they will be a main line of high performance FC on the market. STM32F7 with built-in UART inverters solves so many issues STM32 F4 boards…

How to connect APM Power Meter to INAV
This topic was eluding me for some time now. It’s time fix the problem and finally present a short tutorial how to connect 90A APM Power Meter for flight controller boards running Betaflight / INAV software and equipped with Current Meter ADC input. I will not show where to connect APM Power Meter to flight…

Using PCA9685 with INAV
The PCA9685 PWM driver working as servo extender is no longer supported in INAV. Use S.BUS output and S.BUS servo extenders instead One of the hardware limitations of flight controllers that usually multirotor users ignores is a number of PWM outputs. To fly a quadcopter you need “only” 4 PWM outputs. Since most FCs have…

INAV: how to setup asynchronous gyro
This functionality was removed from the code together with INAV 3. Do not try to set it up, it won’t work. Just flash latest INAV and enjoy the flight without any hassle Your Uncle Good Advice Together with version 1.4, INAV introduced asynchronous gyroscope processing. What is async gyro and why it is useful to…

Mastering INAV Accelerometer Calibration – Step-by-Step Guide
One of the most often forgotten tasks required to bring the most of INAV, is good accelerometer calibration. Why? While flight controller software like Betaflight use accelerometer only to compute UAV’s body inclination (Angle and Horizon modes as well as artificial horizon), INAV uses it also for position estimation. INAV not only has to know…
