Step 1 consists of preparing the M5Stack AtomS3 lite module with the Atom v2 GPS. Simply place the Atom S3 on the Atom v2 GPS. Regarding food: For testing purposes, the module can be powered via USB-C. Next, connect the Adafruit PowerBoost 1000C module by connecting the red wire to 5V and the black wire from the Grove connector to GND. Connecting the LiPo battery to the Adafruit module (being careful to observe the correct polarity) will power the AtomS3 lite module. It is po

The first version of the anemometer is finished. Positioned on one of the autonomous buoys, it allows the wind speed on the body of water to be measured and transmitted to the remote display, which is located at the level of the radio control of the boats.

Le GPS est intégré dans un boitier étanche qui ferme la trappe du df95 We now have four GPS units to mount on DF95s, allowing us to track speeds in real time on a display near the remote control. Each unit has its own USB rechargeable battery. A magnetic switch allows the GPS to be turned on/off without opening the cover. The data transmitted to the display can be recorded onto an SD card and then replayed.

Three major components wirelessly transmit, using the same protocol (ESP-NOW), information allowing for the replay of a training session afterwards and the study of options taken in relation to other boats or according to the wind: Autonomous GPS buoys broadcast their positioning every second. One or more anemometers transmit the wind force over the body of water. The boats' GPS systems also broadcast their positioning every second. Le boitier bleu contient le GPS du bateau T

Three DF95s were equipped with GPS for training with three autonomous buoys, one of which had an anemometer. The following replays were used for debriefing and to refine race strategy.
