PIC18F4550 Pinguino Board for High School Students

[Leonardo]

In the past few weeks I have been working in a Pinguino board based in the PIC18F4550 with pedagogical purposes.

Pinguino PIC18F4550 DevBoard

   

This board will be used in a high-school by students to develop electronics systems. The school is located in Trelew, province of Chubut, Argentina.
(We really close to real Penguins, in fact we can visit them at Punta Tombo, the so called "paradise of the penguins").

The idea behind this design is build an ecosystem around the Pinguino environment, with shield/capes and everything needed to quickly setup and run complex systems.

E.g. 16x2 LCD Shield

   

The design was intended to be built by students or hobbyist with some knowledge in electronics, and for that reason the pcb is single side, all thru-hole, to simplify manufacturing.

As soon as I get build some new shields, I will upload them.

I hope you like, and find it useful.

Any comments or suggestions are greatly appriciated.
