Check the wiring of the “In” and “Out” pads of the PCB. From what I can make of the photos, they appear to be reversed on both sides. (But I can’t see them clearly, so I’m guessing.) The blue wires at the “In” & “Out” pads on the PCB need to be connected to the pad marked with a “T”.
Do you have any voltage readings for the ICs to compare with those listed in the build docs?
