Item: 272917463767 Replace PL2303 USB TO TTL 232 RS232 Serial Port CH340 for Arduino PIC AVR Modbus. I particularly like this design because, you can move around with your laptop, while all the electronics is connected to your machine through a flexible cable, unlike the other adapters discussed above.Seller: canton-electronic ✉️ (24,618) 99.3%, You should be able to find a cable for that pretty easily. The chip itself is relatively big, and most board comes with a USB-B-Mini connector.
Once driver is installed correctly, this is a very reliable board to work with your electronics projects.
This chip is produced by FTDI, and drivers for all popular operating systems are available on their website. While it is still dead cheap, it is relatively expensive to the other devices discussed in this article. This could be the oldest of all these USB-TTL chips. I have mainly tried this for driving small serial devices and never faced an issue with CP2102 or PL2303. But once the driver is installed, everything works as expected. This device also needs a kext to function. The form factor of the chip is also very small and the boards also are very small because of the same reason. Out of all devices I tested, this one is the best because of the availability of technical support and documentation available online. Some variants also provide flow control pins, but I have not used it. Prolific provides necessary drivers for this device, and works very well on mac platform. The board is often covered in a plastic enclosure, prevents dust and dirt accumulating. Again, most of the electronics is within the chip itself. This is a decently built device, and works perfectly well on most operating systems. This built by Prolific Technologies, and it is a decent device. PL2303 A USB to Serial adapter based on PL2303 I have also noticed that a number of cheap Arduino clones comes with this chip, and I recommend not to buy any devices interfaced by this particular chip, if you are using a mac. Looks like something is really wrong with this device. Whenever this device is plugged into my USB port, either the mac restarts, or it does not boot at all. The driver (basically a kext on mac) broken something on my machine. The only problem is that, it doesn’t fucking work!. The board I have comes directly from china, and the build quality is very good. The board has not anything more than a few electronics apart from the chip itself. Thanks to its gold plating around the board. The board is relatively big compared to other products available in the market. This chip comes from a chinese manufacturer named WCH. All have one 5v and 3v3 output along with the TX, RX and the ground. The host machine used for the comparison tests is a Late-2013 MacBook Pro.Īll of these devices have some common traits. The protocol adapters discussed in this article are the following. I have personally purchased and used a couple of them and I think it would make sense to compare these and find out which is the best. This article is to compare a set of USB-to-Serial adapters from different manufactures. Napster's Experiments with Freedom USB to Serial Adapters Comparison
