“The 555 Micro” Kit

£11.99

Push your soldering skills to the next level with the latest in our popular discrete 555 timer rage – “The 555 Micro”. Measuring just 28 x 36 mm and featuring surface mount components, this is the challenge you’ve been waiting for.

 

Description

 

From its beginnings in 1971, the humble 555 timer IC has found itself at the heart of many designs.

Now you can find out what makes the 555 timer tick and build your own with this discrete 555 timer educational kit, while at the same time pushing your soldering skills by practising soldering SMT components with package size 1206 (resistors) and SOT-23 (transistors).

Kit contents:

  • Instructions (pdf download)
  • High-quality PCB
  • All necessary components to build the kit

Requirements:

To complete this kit you’ll need the following tools.

  • Soldering iron with a fine tip
  • Solder
  • Flux
  • Solder wick
  • Small side-cutters
  • Tweezers
  • Flux remover / Isopropyl alcohol
  • Magnifying glass
  • 5V dc power source to use the kit

Handy tools to have “just in case”

  • Solder paste & hot air soldering gun (great if you have, but not necessary as a soldering iron with a fine tip can be used)
  • Oscilloscope
  • Digital Multimeter

Example uses:

The astable circuit produces a square wave output, frequency derived from externally connected resistors and capacitor.
