This 2x18 header strip is very useful to connect Arduino shields. Primarily intended for the Arduino Mega. They can be used with Arduino shields because of their height.
DIP breakout board for SOT23 packages. This will work with MOSFETs, Transistors, Voltage Regulators, etc.
Pins are 0.1" spaced for breadboard applications.
These large Tiller Traction Lug wheels are 13" in diameter. They come as pair and have steel 5/8" diameter shafts and bearings.
