Isolated USB to TTL UART RS232
JST XH connector soldered
Transparent sleeve Mounted on the board
Description
The smallest USB to UART with isolation! Working at max 3 Mbaud and 5 to 1.8V
I was using a cheap USB serial converter, but sometimes they didn’t work correctly and I was losing time.
So we decided to design our own customized board, with only the essential pins and the possibility to work at 1.8V
With the galvanic isolation and the possibility to work at different logic levels according to the target voltage.
What makes it special?
Thanks to the digital isolator the computer and your target board are electrically isolated.
The noise coming from your computer doesn’t enter in your target board, this can be useful when you are working with sensible analog circuit.
This device is very helpful when your target project is not connected to ground.
The voltage levels of TX and RX are the same of your target board. This means that it doesn’t matter if your board is working at 5V or 3.3V or 1.8V, the logic levels are always correct!
