• Prototyping Toolkit
• No Soldering
• Pros.
– Easy to use
– Testing with real components
– Re-usable
• Cons.
– Not good for mass-scale development
– Unstable
– Impossible to use high frequencies
– Larger footprint / space consumption

Memo
• Parts which looks alike
– Blue LED (wide foot)
– Green LED
– Phototransistor (normal foot)
• Colors of the jumper wires does not have a
functional meaning
– But, there are some formal rules
– Brighter : Higher Voltage
– Darker : Lower Voltage
