Above is the diagram for the PU-18.
All of the points are fairly easy to solder to.
Here are some tips I have for you when you are soldering your chip into the PU-18.
- 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.
- A good place to put the chip is underneath where the legend is, towards the middle of everything.
- Use a multimeter to probe around for alternative VCC and GND points closer to where you position your chip for a cleaner installation.
This section displays example installations to help you get a better understanding what a successful installation looks like.
