Installation tips

Here are some tips I have for you when you are soldering your chip into the PU-20.

• Cut your wires to be as short and direct as possible.
• You don’t need to connect pins one and two of the ATtinyX5 chip. Just desolder the wire.
• The DATA pin can be trickier to solder, make sure you don’t use too much solder or you risk bridging pins on the chip.
