rapide555

Rapide555 is a board of my RapideXXX series, small boards for quick prototyping, with everything you need around one component. This time, the all famous 555!

Presentation

Principle

Small board, monopurposed or multipurposed if better. For me 555 rhymes with PWM, so that will be the base business case (<- I'm working too much). Then around that I want to be able to hijack that quickly into other fun use cases of the mythic 555: monostable, on-off button etc... I won't fit them all, there's entire books about 555 circuits! Just make sure I have enough pins free for soldering the puppy in other config than PWM.

Points of interrest

Implementation

Bill of materials

  • 555 in DIP format (I like it retro, and 8 pins anyway you're not saving much with the SMD version)
  • PPTC?
  • Power regulation?
  • 2 free PCB holes per pin, in case
  • Solder switch ready to close to immediately get a PWM config
  • Optional status LED
  • Schematics
