The 4017 Light Chaser SMD Trainer by MitchElectronics is a light chaser made entirely with SMD components, and the goal of this kit is to help teach SMD soldering. RoHS and REACH compliant, ideal for classrooms and workshops, and superb for beginners looking to improve their soldering skills!

This kit is part of the SMD Trainer range that only uses SMD parts to test out your soldering skills. This kit provides all the parts needed to create the famous 4017 light chaser circuit that shows a light moving across a line, and the speed of the moving light is controlled via the SMD potentiometer. Before making this kit, be sure to read our SMD soldering guide found in our resources page, and pay extra attention when positioning components because de-soldering SMD parts can be extremely challenging.

The 4017 Light Chaser SMD Trainer is ideal for those learning to solder SMD parts, and the Soldering Guide under our resources page guides you through how to identify SMD parts, how to solder them, and things to watch out for. This kit can also be used for unique displays, props, and unique interfaces that use LEDs for visual interest. Finally, because this kit works with PP3 9V batteries, it is extremely useful for classrooms and universities where students are introduced to electronic components.


Note that product specifics such as output frequency depend on the tolerance of the components. The numbers provided here are an approximation only.

All parts sold by MitchElectronics are compliant with RoHS and REACH directives which ensure that they can be used in commercial environments as well as complying with environmental laws.
