CMOS Steezer Colour Build Guide

Please see the Bill of Materials at the end of this document for placement of components.

1) Install resistors.  Use a digital multimeter to identify and sort all of the resistors with the kit.  If you don’t own a DMM, you may refer to a resistor color code chart.  You will note that the BOM indicates that R9 is empty.

2) Install ceramic capacitors.  The 10pF caps are blue and the 100nF are yellow.

STZ-Build-13) Install IC sockets.  Make sure that the notch on the socket lines up with the notch on the silkscreen.

STZ-Build-24) Install film capacitors.  The 100nF cap says “u1” on it (short for .1uF, which is the same as 100nF).  The 47nF says 47n on it.

STZ-Build-35) Install electrolytic capacitor.  Note that the longer leg on the cap is the + side.  Ensure that it goes in the hole indicated by the + on the PCB.

6) Install Samtec header.  This installs from the bottom.  Make sure that it sits absolutely flush with the PCB.

STZ-Build-47) Install standoffs.  These install from the bottom.  Make sure that the locking end of the standoff goes into the PCB.

colour-connectors18) Install ICs.  Both ICs have notches in them.  The notch aligns with the notch in the socket and on the silkscreen.  You may need to bend the pins in a little to get them lined up with the holes.  Just be careful doing so.
