Review: No instructions doesn't seem to work as expected - Very poor set of instructions and pointless video on you tube. Trying to convert a UART signal from a USB device straight into an RS232 device, tried used the RX and TX pins on the board and also the USB to pass through data doesn't get sent. Not sure why I need software and driver for this as I'm not trying to connect to a computer I just want to convert USB data into RS232. Shame there isn't more instructions or a telephone support so I guess ill be returning
Review: Sehr guter UART-Konverter - Ein prima Kompromiss zwischen einem einfach (der nur TXD/RXD/CTS/RTS anbietet) und den ­– meiner Ansicht nach überteuerten ­– C232HD-basierenden. Dieser UART-Konverter hat alle wichtigen Pins, insbesondere RTS und DTR, welche bei vielen eingebetteten Systemen (Arduino, ESP32, etc.) benutzt wird, um einen RESET auszulösen (damit man in den Bootloader/Upload-Modus kommt). Das Preis-/Leistungsverhältnis stimmt.
