Step 1 consists of preparing the M5Stack Core2 module. There's practically nothing to do as it comes pre-assembled with its screen, battery, and microSD card reader. All that's left is to format the 32GB microSD card to FAT32 and insert it into the card reader . Wi-Fi connection and time setting In order for the module to synchronize to the exact time and allow retrieval of data recorded on the microSD card via Wi-Fi , without having to remove it, you must enter your Wi-Fi

Step 1 involves connecting the M5Stack AtomS3 with the voltmeter and the anemometer motor. Step 2 involves installing the software inside the M5Stack AtomS3 module. To easily install it on the M5Stack AtomS3 module, you can use the M5Stack Burner utility which allows you to download and install the software very easily. Step 1 — Download and open M5Burner Download M5Burner for your system (Windows/macOS/Linux). Unzip the archive and open the M5Burner application. Tip: On macO

Find all the photos from the Class M regatta on 16/11/2025 at the CNCR, in Choisy Le Roy. We used three autonomous GPS buoys, two for the starting line and one as a leeward gate. They performed well, except for one whose computer shut down in the early afternoon, after several stable hours. Analysis of the problem to follow.

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. Anémomètre accroché à la Bouée autonome Les données sont transmises sans fil (protocole ESP-Now) à l'afficheur qui se trouve sur la radio commande The wind speed display is shown in real time to compare boat speeds to wind
