Funktioniert wie es soll.

Le convertisseur USB vers 4 ports TTL est de bonne qualité et de finition impeccable. Il est reconnu directement sous Windows 10 & 11.Il est fourni avec tous les câblages nécessaires : 1 câble USB et 4 câbles pour les ports UART. La connectique des câbles UART sont d'une part (côté du convertisseur USB2UART)) un bloc de 6 câbles avec détrompeur et d'autre part (côté à connecter sur carte électronique) 6 connecteurs individuels (de type Dupont).La sélection 5V/3.3V est très utile si vous utilisez le convertisseur sur un système ne supportant pas une tension supérieure à 3.3V.Bon produit dans l'ensemble

This device helps a lot on my bench.I have several arduinos to acquire data on my bench and this device simplify my installation.It is easily recognized by Windows 10 and above, as a 4 channel UART device.It was a good choice to have ordered it.

Geliefert wird der Converter gut verpackt in einem ESP-ZIP-Beutel, zusammen mit einem USB-Anschlusskabel und vier Anschlussblöcken in einem ProduktkartonDas Anschlusskabel ist ca. 1,2m lange und hat eine USB-A Anschluss und einem Ferrit in der Leitung. Der Converter wird ohne Treiberladen unter Windows 11 erkannt und zeigt unter den Com-Schnittstellen vier unterschiedliche Ports auf.Die Pinnbelegung ist auf dem Gehäuse aufgedruckt, sodass man z.B. einen Mikrocontroller anschließen kann. Das Metallgehäuse ist schön stabil. Die Umschaltung der VCC zwischen 3.3V und 5V ist klasse und macht das Gerät vielseitig einsetzbar.Mein Fazit ist, dass es sich hierbei um einen robusten TTL-Converter handelt, der mit allen benötigten Kabeln geliefert wird. Von mir einen Daumen hoch und volle 5 Sterne ⭐️⭐️⭐️⭐️⭐️ :-)
