ArteryTek AT32 Flight Controller – NeutronRC F435
OK, I’m kind of hyped with this! What you see on the image looks like an any other flight controller, right? Looks again! It’s not STM32 but ArteryTek AT32! And F435 as a bonus 😉 With the continuing chip shortage supply of STM32 is limited and prices high. Maybe have an alternative source of MCUs…

Matek F765-WSE flight controller preview
Who makes the best fixed-wing flight controllers? Most probably Matek. Their series that begun with Matek F405-WING in 2018 is still going strong. Some models are end-of-line and new ones are created. The Matek F765-WSE is the next generation of Matek WING flight controllers that will appear on the market in late Q3, early Q4…

Beitian BN-180 GPS Module Troubleshooting
Beitian BN-180 is one of the most popular small, and cheap GPS modules used with INAV on airplanes, or on Betaflight on quadcopters. Most of the time, they work just fine, but I discovered that they could make problems from time to time. Here is a shortlist of possible issues and solutions for Beitian BN-180…

STM32 F1, F3, F4, G4, F7 and H7 flight controllers
Currently, almost all flight controllers we use on our multirotor FPV drones and airplanes are powered by microcontrollers from an STM32 family. When we say about flight controller families or generations, we refer to them by the family of the MCU. For example: F1 flight controllers are no longer supported or You should get F7…

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…

Hardware revisions of Omnibus F4 flight controllers
The Omnibus F4 series is one of my favorite flight controllers. Two of my quads are flying thanks to them. They might not be the best or the famous ones, but they get the job done. And that is what counts. Unfortunately, they are not free of faults (and what is?) and each next revision…

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…

Omnibus F4 Pinout
Omnibus F4 is a new family of All-In-One (AIO) STM32F4 based flight controllers with integrated OSD (On-Screen-Display) for FPV purposes. Basically, it is Airbot F4 / Flip32 F4 with added MAX7456 and some minor tweaks.

Connecting ultrasonic rangefinder (Sonar) to INAV
Keeping constant altitude with a drone is not a trivial task. Specially, if drone is supposed to keep give altitude very precisely few meters above the ground. One of the reasons for it is difficulty of reading precise altitude. Barometer can drift when atmospheric pressure changes and can produce a lot of noise. GPS is…
