Step 8
–
3.3V voltage regulator &
2n2222 transistor
Important: These two components are very similar
so make sure to read the text on the components
carefully because that is the only way you can
recognize them.
(Please note that the text on your transistor may
vary
and have something like “KSP 2222A –
708”
written on it. This happens because the different
manufacturers tend to write unique serial numbers
on their components)
Solder the regulator on the board where “IC2
3.3V” is marked and the transistor to the
spot with “T1 2N2222” marking on it.
Be careful to turn these components on the
right side!
Important: Make sure the flat side of the
regulator and the transistor faces down
towards the board, this is achieved by
bending the pins of the components by 90
degrees.
