SH-U09C3

Great Product. Easy to use. Be carful to have GND connected when using the device, I had a ground pin disconnect on my application side and killed 3 units when I plugged them into the computer.

I needed a serial interface for a commercial prototype that offered total isolation. I'm familiar with the FT232RL and prefer it over other USB-to-serial chips because of broader platform compatibility, especially with newer versions of Windows. The DSD unit worked flawlessly out of the box, connected with my Windows 10 system and my prototype and has been running experiments all day without a hitch. I had to take isolation a step further by removing the DC-to-DC converter (the big black rectangle) and supply 5v power from the prototype. The nice acrylic case the DSD unit came in was easy to disassemble. A little prying with a jeweler's screwdriver and voila... I had access to the board to remove the converter. Afterwards it snapped back together without a fuss. This is a clean, well-designed unit that does what it's supposed to do. Highly recommended.

This device worked perfectly. I wanted the serial data levels to be powered externally and was a bit confused about doing that although I found in an answer that you can remove the 3.5/5 jumper altogether. That did it.

This adapter works great. It is a nice design and actually has a case on it unlike other adapters that are just a bare board. It was tested to make sure it was really isolated and it is. If you need an isolated TTL adapter with the FT232RL chipset this is the one to get.

Worked perfectly to allow me to program and monitor serial output of my smart plug while it was running off AC power.

Very well made. Works great. The case is nice touch.

It is working well good price

The pullup on RXD is way too strong, 4.7 kohm. I had to desolder it to get incoming data to be read because the slave device couldn't fight that resistor enough (dropped to like 0.6 volts when it needs 0v). After that, isolation works at 115200 baud. I dislike that this sends power to target device. Really should just receive power for the return signals -- I'm pretty sure in noisy environments, it's going to need to be removed.

Works as expected, no problems encountered so far.

Deze gekocht als alternatief kabel voor de victron ve aansluiting. Zoals de foto laat zien werkt het dus zonder problemen. Deze is ook geïsoleerd zodat je meerderen van deze kabels kan gebruiken op een usb hub .

Quand on cherche une liaison USB-ttl fiable, ce composant a une bonne puce FTDI, avec driver compatible windows même >10, linux ubuntu, mac, et il est isolé, donc plus de pb de CEM et tension secondaire disponible. Attention, il y a plusieurs versions chez le fabricant. Ca m'a sauvé pour faire fonctionner un appareil et le PC, car sinon les deux plantaient avec un câble non isolé. Je crois que ça existe aussi chez ce fabricant en version USB-UART, les signaux UART étant inversé par rapport à ttl, mais en 3 ou 5V contrairement au RS232 en -12/+12V.

Used on victron ve direct. Would be nice to turn off the LED power and data indicators but not essential. Not checked the maximum data rate, works well at the lower end.

Very good. Auto driver in win11 with protection of isolation. Worth of money
