Sounds interesting - a little board, manufactured? With 5V supply? Perhaps with 5V-tolerant I/O, or maybe not? Welcome! |

The FPGA has input and outputs at 3.3V. A low drop linear voltage regulator can also be added, allowing the board to be powered at 5V. SN74LV4T125 with 5V voltage supply can provide the up translation for outputs at 5V. SN74LV4T125 with 3.3V voltage supply can provide the down translation for inputs at 5V. |
