Did its job to serial attach & revive my semi-bricked router (mx4200 v1).

Damit ich mein Laderegler von Victron mit dem PC verbinden und auch auslesen kann, habe ich mir diese Modul von xicoolee bestellt.Es wurde schnell und gut verpackt geliefert. Im Lieferumfang war auch neben dem Board selbst eine recht ausführliche Anleitung/Modulbeschreibung (engl.), Ein Stecker-Verbindungskabel und ein USB-Adapter.Das Modul sieht qualitativ hochwertig aus und ist auch sehr sauber verarbeitet. Es ist auch endlich ein Modul, das mit USB-C Anschluss ausgestattet ist und besitzt noch zusätzlich einen Switch, mit dem man zwischen 3V und 5V manuell wählen kann.Die Verbindung zwischen meinem Laderegler und dem PC konnte ich, so wie ich es mir vorgestellt habe, realisieren. Die Daten werden problemlos übermittelt und ich bin somit mit dem Ergebnis sehr zufrieden.Somit vergebe ich in der Gesamtwertung 5 von 5 Punkten.

Ce produit répond parfaitement à mes attentes.Aucun souci de compatibilité avec mon imprimante 3d (de la marque Qidi) pour y charger un firmware custom.Je ne peux que recommander.

Preso per la programmazione di ESP32/8266 e simili, rispetto alle alternative economiche ha una presa USB-C, che sta diventando lo standard ormai ma è fornito anche di un adattatore per USB-A e, cosa non sempre comune, anche del connettore dupont per i collegamenti, cosa che evita di usare cavetti sparsi.Il cambio da 3.3 a 5 V si fa con un semplice interruttore a scorrimento, non ci sono quindi pin distinti ed occorre fare attenzione di volta in volta a selezionare il voltaggio corretto.Non ne ho avuto bisogno perché probabilmente li avevo già installati, ma servono probabilmente i driver per il chip USB to UART, facili da reperire ovunque. C'è perfino un manuale cartaceo.
