Versatile Board for AVR Microcontroller Circuits

Platino, the greatest star of the support act

The name Platino is a playful reference to the French and German word ‘Platine’ meaning ‘circuit board’, with a slight wink at ‘Arduino’. The goal of this project was to design a PCB that would be useful for many applications based on Atmel's ATmega MCUs that may need an LCD and/or push-buttons and that can be easily programmed using WinAVR, AVR studio, BASCOM, Mikro-C or Arduino. The dimensions of the board are adapted to a standard Bopla enclosure so it is easy to finalise a project properly.

Gerber file

CAM/CAD data for the PCB referred to in this article is available as a Gerber file. Elektor GREEN and GOLD members can exclusively download these files for free as part of their membership. Gerber files allow a PCB to be produced on an appropriate device available locally, or through an online PCB manufacturing service.

Elektor recommends the Elektor PCB Service service from its business partner Eurocircuits or AISLER as the best services for its own prototypes and volume production.

Components

The BOM (Bill of Materials) is the technically exhaustive listing of parts and other hardware items used to produce the working and tested prototype of any Elektor Labs project. The BOM file contains deeper information than the Component List published for the same project in Elektor Magazine. If required the BOM gets updated directly by our lab engineers. As a reader, you can download the list here.
