A bidirectional levelshifter designed in KiCad to control higher voltages on an FPGA.
Access the interactive BOM here.
I designed this board to interface a keyboard over a PS/2 port. The logic level of the keyboard is 5V whereas the FPGAs IOs run at 3.3V. The pmod-levelshifter relays a signal from the HV side to the LV side and vice versa. When no side is driven, the lines are pulled high. 8 IOs are supported.
