This is an extremely small version of the drawdio tone generator.

For this build i have used 01005 capacitors and resistors, these are 0.2x0.4mm in size and pretty hard to hand solder without magnification.

For reference:
the whole board is about 12x13mm and the leg pitch of the 555 is 0.635mm.
Distance between the three 01005 components placed in a row is 0.6mm.
There are a total of five 01005 components on the board.
