Marminino, o Arduino Cearense! by Daniel Almeida Chagas
The marminino project is an arduino minimal, mounted in an very simple PCB, focused to be very simple to build, cheep, and easy to use. The marminino is an open hardware fork from the Nanino project, initially made by Johan von Konon, and updated by Brad Luyster.The project goals are:
- Single side PCB, who can be made for beginners and still with great results (big traces, with big spaces between).
- Minimal components, just the essencial.
- Some capacitors for a better battery powered experience.
- Jumper for selectiong the power source (FTDI or Batteries).
- Mounting holes attach a 4 AA battery support.
- Better led position.
- New component organisation.
- New switch position
- Two new female bar pins for easy prototyping with or without mini breadboard.
- Complete information about pins on silk screen.
The board was created using DipTrace software, who is freeely available for small projects.
