I wanted to have a 555 development board so to speak, ready to configure and use in various projects without the need to have 3 different boards for each of the main modes of operation of the chip.
I also wanted to make this as a soldering kit, easy to build and fun yet practical.
This little board can be configured as Monostable, Bistable or Astable with 3 jumpers.
You can configure its timing elements via two trimmer potentiometers but if needed you can also use a different capacitor... its all TH so easy to play with and fun to build.
