This is a regulator board. It has a terminal strip with a common ground, input, and 5VDC output. Includes fuse, filter, and power LED. It uses a Dimension Engineering Switching Power Supply for maximum efficiency and isolation.
The switch mode voltage regulator is designed to be the easiest possible way to add the benefits of switch-mode power to a new or existing project. The switching regulator will allow you to take a higher voltage and it step down a 5V output in a compact, efficient manner. The switching regulator is pin-compatible with the common 78XX family of linear voltage regulators used in TE-045-000.
We use these in our ATRs to supply a regulated isolated efficient 5V supply from a battery to our motor controllers and/or RC receiver. The board is spaced out on 0.1" or more grid that is easy to solder with no surface mount components. The board is about 1.25" square.
Use these roll pins to fix sprockets to a shaft and keep them locked in place.
These large Tiller Traction Lug wheels are 13" in diameter. They come as pair and have steel 5/8" diameter shafts and bearings.
