A new flight data recorder has been brought into service and is currently being tested. See this page. It uses the new possibilities linked to the recent redesign of the CAN bus architecture. It is based on an Arduino Nano ESP32 board; see the microcontroller boards page, which has been revised and updated.
- March 26, 2024
A new page about the CAN bus has been added in the software section. At the same time, a new configuration of the CAN bus has been implemented, where the old UART communication line between the AHRS and the EFIS main unit has been removed. The AHRS is now connected to the CAN bus. Of course, many software updates were made for that purpose. New and old software versions are available to download on GitHub. Many minor updates were also made accordingly to the EFIS and AHRS pages.
- March 10, 2024
A new page about variable reluctance sensors and signal conditioning has been added in the hardware section.
It is now possible to attach files to comments: images in JPG or PNG format, ZIP archives, and documents in PDF or TXT format. Furthermore, visitors posting comments will now be notified by email as soon as the moderator has approved them.
An advice page for writing comments has been added.
- February 13, 2024
The EFIS page has been thoroughly reviewed for clarification purposes.
- February 11, 2024
GNSS configuration has been clarified. AHRS and GNSS configuration pages have been updated
- November 9, 2023
The Teensy Micro-EMS page has been extensively revised. New versions of the PCB (v 4.1) and software (v 4.2) are available, correcting the initial defects affecting the rev counter function and providing several improvements.
The EMS page has been updated accordingly (new software version 1.5).
- May 8, 2023
Many pages have been updated. In particular, Gerber and drill files are now available for download for all PCBs, in addition to Kicad files, to make ordering these PCBs from manufacturers easier.

The new Teensy Micro-EMS page is now online. A much more advanced version compared to the previous Micro-EMS, which was based on an Arduino UNO board.
- April 13, 2023
The “U-Blox NEO-M9N GNSS Configuration” page has been added. The AHRS page has been modified accordingly to better specify the exact GNSS configuration options.
- April 11, 2023
The EMS page has been added.
- December 16, 2022
The Micro-EMS page has been updated.
The French version of the EMS page is now complete, with software and Kicad files ready to download. English version as soon as possible.
- November 18, 2022
On the EFIS page, the EFIS V2 Kicad files and source code have been updated. There was an error in the electrical diagram; two connection pins of the rotary encoder were reversed, which did not allow the benefit of the four hardware quadrature encoder channels available on the Teensy 4.1. This bug is now fixed, allowing for the implementation of the Hardware Quadrature Library for the Teensy 4.x in the source code.
- November 6, 2022
The Current measurement page has been updated with a software example.
The power supply page has been added.

EFIS V2: Kicad V6 files and source code are now available for download on the EFIS page
- October 3, 2022
The EFIS page has changed with the introduction of the V2 EFIS.
The AvionicDuino AHRS software is now available for download on the AHRS page.
- October 1, 2022
The Flight Data Recorder page has been added.
We are actively working to improve the quality of our English; many pages have already been revised accordingly. There is still a lot of work to do. We ask for the reader’s indulgence.
- September 30, 2022
The AHRS page has been modified by introducing our new open source open hardware AHRS. Download links for the schematics, the realization of the printed circuit board, and the software will be added soon.
The Micro-EMS page has been extensively revised, introducing the Micro-EMS V2.
- September 26, 2022
There has been a lot of progress over the past few months. The EMS page will finally be written soon! Currently, this page only contains a short in-flight video of the new EFIS-EMS, the EFIS part of which mainly benefits from a new homemade AHRS. This AHRS’s electronic schematics and open-source software will be released soon; the AHRS page will be modified accordingly. This new AHRS settles the question of the commercial unavailability of the previous Naveol system. The EMS works perfectly. The visual interface is currently bare in text mode, facilitating flight tests. The schematics, KICAD files, and open-source software will soon be available on the site.
