The XEP1541 adaptor
You need the following parts to build this adaptor:
Step 1. Build the board of the adaptor, cut it to shape and drill the holes in it, based on the board diagram (300 DPI resolution). This diagram shows the board as viewed from below.
The cathodes should be pointing towards the pins in the right column of the table, which corresponds to the right when the adaptor is viewed from its back side, where the DIN port and the user port edge are.
The parts should be soldered the following way onto the board. This diagram shows the board as viewed from above. Note the small band on the right side of the diodes.
You can find the description of all parts used on the diagrams at the legend page.
