Look at the resistor and try and find a gold or silver outer band. Hold the resistor so that band is on the right.
Look at the first color on the left. Using the chart above, calculate the first value. For example, if the first color
band on the left is orange, then the first value is 3. Look at the color band next to the first one, just off to the
right and get that value. Let’ assume the 2
nd
band is also orange. Now, the 3
rd
band is the multiplier. Let’s say
that color is red. Red is 2 which means we just put 2 zero’s at the end of the value. So, it goes 3 (orange), 3
(orange), 00 or 3300. Simplify that to 3.3K by dividing by 1000 and now you have calculated the resistor value.
This is a quick explanation on how to calculate the resistor value. There are many web sites out there to help
you out but the parts chart gives you color values to help you out.
There are 3 different types of capacitors on the Micro-KIM. The easiest way to figure them out is just put them
into 3 different piles.
The 1uF looks different than the .1uF caps and the .22uF caps.
The .22uF caps look close to the .1uF but the value on the capacitor is different.
The .22uF should have the number 224 on it but the number scheme on capacitors can vary.
On the .1uF capacitors, they should say 104. On the 1uF it should just have a 1 on it.
The 2 diodes are easy to identify. The 1N4001 is a larger black diode with a silver strip.
The 1N4148 is slightly smaller and looks like it’s made of glass.
It is important to note that diodes are polarized. The white or black stripe tells which way they mount on the
PCB. Pay attention when building your kit to ensure that the diodes are in the correct orientation.
The DB9 connector is your serial port connector and looks like a standard 9 pin connector.
The power supply connector is a male jack that fits many standard power supplies.
The 40 pin header has no incorrect orientation and can be mounted either way. However, one side is shorter and
that is the side that goes into the PCB. Make sure the longer end sticks up when installing on PCB.
There should also be 2 jumper post and 2 shunts. The JP1 on the Micro-KIM is essential for operation but needs
to be removed if an expansion board is used to decode memory differently than what is done on the Micro-KIM.
There are a total of 23 tactile push button switches that are easy to identify.
The power switch will mount next to the power jack on the PCB and has 5 mounting tabs on the bottom.
The SST (single-step) switch is black and sits with the keypad.
There is also a CD containing manuals and text files of some software. This completes your inventory check of
the Micro-KIM single board computer.
