What is it?

This is an un-assembled kit containing all the components to assemble a PWM led dimmer / DC motor speed controller based o the widely available NE555 timer.

It is excellent for educational purposes or for hobbyists that want to practice their soldering skills while building a useful electronic circuit. The kit is suitable for beginners thanks to the clear markings on the board to enable simple assembly. Note: Unfortunately there is a missprint on the silkscreen, it says NE556 instead of NE555. Luckily it is only a cosmetic error.

You will need basic soldering tools and skills to complete the assembly.

A video link showing the assembly will be provided upon purchase to simplify the installation.

The circuit can be used to control the speed of DC motors, or as a dimmer for LED lamps. Based on pulse width modulation (PWM) using the NE555 timer IC. Max 5A. 5-16V.

TAKE NOTE: In this batch there is a missprint on the silkscreen on the board, it says NE556 instead of NE555.

Order will be handled within 5 business days starting as soon as payment is received. Buyer will be notified by email as soon as the parcel has been handed over to the postal service.

I needed the ability to dim several led strips from almost turned of to fully lit up and did not like the idea of tying up several microcontrollers only to dim some leds. After a bit of reaserch and digging into knowledge I had almost forgotten I had this circuit is the result.
