  • It works, but I received something else

    posted by DorinC on 00:42:23 G5T 25/05/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: It just works as a USB to serial converter without control lines (no DTR). It is small, it has a fair price.

    Cons: The one that I received doesn't have the pads on the PCB with control lines (I want DTR for Arduino) like I saw in the pictures when I ordered it. It is like SKU: 202547, with small differences. On mine, the TX and RX are reversed (the pin marked as TX is input), it took some time to figure out this. The RST pin is an input signal that resets the onboard chip, I think it is unusable in most cases.

    Other: Buy this if you want a cheap converter and you are willing and have time to hack around.

    posted by RichS on 17:57:11 G5T 13/05/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: The board is well-made with good solder joints and a secure USB connector. A five-conductor female-to-female ribbon cable is included. The drivers are available from SiliconLabs for the CP2102 chip. The board works with baud rates from 110 and 921600.

    Cons: The board delivered does not have any control lines, just TXD and RXD (along with 3.3V, 5V, RST and GND).

    Other: A nice little board, but I need the control signals (at least either RTS or DTS).

  • Capable USB to TTL converter

    posted by eeyoresan on 04:39:12 G3T 27/03/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Easy to use, has default drivers for Win7. Just connect Rx/Tx and GND to the board and insert it into a USB connector on your computer and your ready to go. Full documentation and application notes for this chip can be downloaded from www.silabs.com.

    Cons: Have not discovered any real cons with this product yet.

    Other: If you need a simple to use USB to TTL converter that is not expencive, this is a great choice

  • The complete USB to RS232 interface

    posted by bigjack65 on 05:02:50 G3T 10/03/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Cheap, small, well usb support, all RS232 signals available. It's perhaps the only full signal interface offered by DX. I've ordered two from 2012/12 to now, and last received have a 5 pin headed flat cable instead of earlier 4 single cables, so it's more simple to connect to Arduino board that requires DTR signal. Both 5 and 3,3V are supplied.

    Cons: Not really a con: both received have little differences from the DX images. In detail, are missed the SPD and SPDI usb control signals. Not a big deal, their use is very not usual, but I've to advise you. Lack connection monitoring, there is a power-on led only. Also, for embedding, is surely much more useful a mini-USB female connector, that seem to be not very usual in DX USB interface. Perhaps, would be better to replace reset line with DTR to comply with FTDI interface.

    Other: Reset is the INPUT line to resetting usb interface so Host OS can re-enumerate it.

  • Good value and goos selection of I/O

    posted by robbage on 19:16:25 G1T 31/01/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Very small. Uses a well known and reliable chipset. Supported for WinXP through to Win8, 32 & 64 bit. Best price for functionality. I needed access to DTR and RTS which are available.

    Cons: A data sheet would be good. What does the reset pin do? Output to reset an Arduio or is it an input to reset the module?

    Other: Excellent value for money and no problems with fake chipset that won't work with official drivers.

  • Good USB TTL converter

    posted by wirewrap on 04:34:12 G1T 27/01/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Does what it is claiming to do. Delivered with a bunch of nice jumper cables that can be used for other things. More signals brought out to connection points DTR data terminal ready, DCD data carrier detect (What it does I have not checked) RI ring indicator DSR data set ready, CTS clear to send. DTR/CTS can probably be used for HW flow control, I have not tried.

    Cons: Seems that the CP2102 does not have a unique identity for each chip so under Windows 7 I have not been able to use more than one at a time. Using a similar FTDI chip, each device gets its own virtual communications port like COM5 COM6 etc. but the CP2102 all devices get the same VCP. Might be a workaround, have not consulted the data sheet for CP2102

    Other: A little expensive compared to other DX products of this complexity level.

    posted by TheCompiler on 16:11:41 G9T 16/09/2012 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: - Has pins for 3.3V, RST, TXD, RXD, GND and 5V, as well as unpopulated pin headers for DTR, DSR, RTS, CTS, SPD, SPD1, DCD and RI. So even if you need hardware flow control or any other rather uncommon features you're good to go. - Works out of the box with Linux with the cp210x module - Comes with a nice colored cable

    Cons: Nothing I can think of really. I'd have liked a 2.54mm to 2mm cable and the unpopulated pins could have a pin header on them as well, but these are minor details.

    Other: Really handy to have one or two of them around when doing embedded development or anything like that. Probably better than SKU 81872 because of the different pins if you need them (also cheaper)
