Daniele Corti

A new PCB project called miniP started in 2010 in Pisa.

This board is the sussessor of the PULSer And Recorder board

The first schematic and layout draft, done by Riccardo Paoletti

miniP vs PULSAR is more compact and can manage isochronous signals from connected mezzanine

Works done in 2010

9U board

6U board

Daniele Corti

The first prototype called miniP board V1.0 realized by Daniele Corti and Francesco Dazzi.

Three boards mounted, one used for BGA soldering tests.

Found little connections bugs and power supply noise during the functionality tests

Works done in 2011
