Used this to upload custom firmware OpenWRT to a Linksys EA7500 router using 1.8V TTL logic, worked great!

シリアル通信なんてRS232Cで9600bpsでやり取りしてるだけだから何だって一緒でしょ？そんなレガシーで単純なシステムに細かい違いとかないでしょ？と思ってたらどハマりした。温度計Center301の3.5mmシリアルポートはUART。TTL。5V。これを満たさないと通信できない。紆余曲折、いくつもUSBシリアルを試した結果これに辿り着きようやく通信成立。長かった。

Commandé pour dépanner un Odroid N2+, je n'ai pas réussi à la faire fonctionner mais cela vient du N2+ qui est vraiment HS.Drivers installés sous Win10 sans aucun problème, reconnu de suite. Les jumpers sont faciles à bouger et l'adaptateur est de bonne qualité, la coque tient bien. Les câbles sont un peu courts (à mon goût).

Si tratta di un adattatore da USB a TTL.Pratico e compatto, adatta diversi livelli logici tra cui 1.8V, 2.5V, 3.3V e 5V.Integra il chip Silicon Labs CP2102 in grado di raggiungere 1 Mbps. A forma di pennina usb, è protetto da un robusto rivestimento in plastica blu trasparente. Nella confezione troviamo:- 1x Convertitore da USB a TTL SH-U09A1;- 1x manuale utente;- Cavo DuPont 1x4 PIN.Sulla scheda PCB sono previsti dei led di notifica per il pin TX, RX e per l'alimentazione. Collegato al pc, viene immediatamente rilevato e pronto all'utilizzo. Lo trovo davvero un comodo strumento per flashare microcontrollori. Il prezzo è in linea con altri modelli simili.
