- insert the protruding pins of the 2×6 header into the top of the hole pattern for J4 on the Multi kit and solder the header pins in place from the bottom side of the multi kit. Make sure the QSB board is flush with the multi kit pcb.
- Add solder into the 2 holes on the right side of the QSB making a connection to the pads for SWD6 and SWD7.
- Attach the QSB to CN9 on the B board using the provided 6 pin JST NH terminated cable. For B boards without CN9 you just solder the wires to CN2 using the provided cable, just like a normal key writing install.
