DIY PIC32 Pinguino Almodovino

Pinguino Almodovino is a DIY development PIC32 board, low cost (least 15 USD).

The board, with few components, is easy to build. The components used mainly are Through-Hole components and only have 4 SMD components.

The board dimensions and format are similar to Arduino UNO (size board is 68.6mm x 53.3mm).

Pinguino Almodovino can use a PIC32MX220F032B, PIC32MX230F064B, PIC32MX250F128B or PIC32MX270F256B (in 28 pin PDIP format).
