Passive components soldering

Now take all the passive components : the amplifier, the slide switch and the buzzer :

Pay attention to the L9110 orientation :

Solder just one pin, check the placement, solder the opposite pin and finally all the remaining pins. Cut the tips as close as possible of the PCB.

Put the slide switch in place, solder just one pin. Check that the switch’s metal shield is flat on the PCB and solder the other pins.

Cut the slide switch pins and legs :

Same thing with the buzzer. The orientation is not important but ensure the buzzer is flat on the PCB. This component is not over the battery.
