Soldering points
Back Home Up Next



The yellow arrows show the points where I soldered the wires.

Prepare a hot glue device to fasten the wires as soon as possible
otherwise you may tear them accidentally off.

I started with the left top, then the left bottom one - as said before,
the connection of pin 9 to 7 is already done under the chip.

The third was the right top (copper plate of pin 4) and the
Last was the wire on pin 4 itself.
