What is it? This is a USB to UART converter based on FTDI FT230X with a voltage translator 74AVCH1T45. Why did you make it? Today the most low voltage MCU and FPGA are working below the 3.3V, the …
Read More…Thanks to the voltage translator 74AVCH1T45 you can use a UART port down to 0.8V.
The voltage level of TX and RX are the same of your target board power supply. This means that it doesn't matter if your board is working at 3.3V or 1.8V or 0.8V, the logic level are always correct!
| Name | Description | Direction | Voltage level |
|---|---|---|---|
| + | Positive power supply | Input | 0.8V - 3.6V |
| - | Ground | Input | 0V |
| RX | UART RX | input | same of + |
| TX | UART TX | output | same of + |
