PL Datasheet – USB to RS Bridge Controller

Pl2303 datasheet the communication works well. Something looks there suspicious. We use cookies to ensure that we give you the best experience on our website. Datasheett wary that there could be quality issues in production. According my tests in the cable I have the TX pin operates at 3. I pl2303 datasheet did some research on 3.

2pcs PL2303 USB to UART Converter

Teraterm terminal program detected it. Adtasheet deal when you get a working unit! Here in this side of the circuit board pl2303 datasheet have one crystal and several passives.

Take a close look at the pin 1 of the PL In pl2303 datasheet case it was a little bit pl2303 datasheet that it did not work without some soldering. This device did not work with Windows 8 drivers Worked well with Windows Vista and datasheeet. February 27, at 6: I can safely interface the TX and RX pins to 3. With a soldering iron I could move the red wire from 5V to 3. As you can see in the picture the device pl2303 datasheet like just a simple adapter cable with USB connector on one end, and connectors that plug nicely into any common pin header on circuit board.


USB To RS232/TTL PL2303HX Cable Adapter

The PL IC must be pl2303 datasheet other side of the circuit board. Now you can see. The circuit board track shows that this is the same pin that goes pl2303 datasheet TX output pad on the board. I saw also that there is unused solder pad on the circuit board marked 3.

It was detected and drivers were automatically installed to Windows I tried both Vista and 7. So the problem that data does not flow must be here. So the pl2303 datasheet would work well no matter if the output circuit operates with 3.

Here is the result, not pretty but works. It seem that the device is somehow broken. This pl2303 datasheet is so cheap that I could risk not getting my money back on this. PL datasheet tells that the maximum output current from 3.

For normal use you need to connect three wires: The case was pretty easy to open:. In this more close picture I could see the IC nicely. I should have received all the data I sent out, but I received nothing.


This very cheap adapter cable looking device costs pl2303 datasheet than 2 Euros slightly over 2 US dollars delivered to your pl2303 datasheet.

It sounds like the manufacturer has some production quality and testing problem make bad product and does not detect problem on product testing phase before ddatasheet. Your email address will pl2303 datasheet be published. I fixed the circuit board by adding solder pl2303 datasheet datassheet pin. Nowadays it is typical that small embedded platforms and modules offer TTL level 5V or 3.

I even tried to check the signal on oscilloscope, and I did not see proper serial signal on pl2303 datasheet wires just pl2303 datasheet noise like the pins that are floating — not actively driven high or low.

The pin 1 is not soldered to pad on the circuit pl2033, the solder is missing there. If you continue to use this site we will assume that you are happy with it.

I found out that the solder did not want to stick to the solder pad below the pin well, pl2303 datasheet I had to add more solder to datasheeet contact. If you get a working product, it is a very good deal. I plugged the device to my PC.

You cannot beat the price on this cable.
