 # LogicAnalyzer
+----
+## UPDATE 12/07/2022
+
+I have received the shifter PCB's and there is an error. The footprints of J1 and J2 are exchanged, so what should be inputs are outputs and vice-versa. Thankfully this is not a problem, as the PCB is completelly symmetric and it has components in both sides flipping the board fixes the problem.

+
+The KiCad project is already updated.
+
+The good news is that the board works like a charm, I have tested it with my clock generator with a 50Mhz clock and it captures every single half cycle perfectly, like if the board was not there :D
+
+So if you want to build your own shifter board, it's ready and tested.
