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.
Thanks to the digital isolator MAX12931BASA+ the computer and your target board are electrically isolated.
Name | Description | Direction | Voltage level |
---|---|---|---|
+ | Positive power supply | Input | 1.8V - 5V |
- | Ground | Input | 0V |
RX | UART RX | Input | same of + |
TX | UART TX | Output | same of + |
