MAKE posted an interview with the developers of the Pinguino Arduino-like platform for Microchip’s PIC18 and PIC32 microcontrollers:
We wouldn’t try to claim that the Pinguino is a “100% Arduino compatible board” as Microchip said for the chipKIT. Our goal is to add functionality to the original Arduino board as we did for 8 the bit version.
They also designed an open source tool chain for the PIC microcontrollers on the Pinguino boards. Notable differences to the chipKIT32 are:
- DC to DC converter instead of a liner voltage regulator, allows for larger input voltage range and lower consumption
- The use of PIC32 on-chip USB instead of using the FTDI chip, this also allows for the Pinguino to act as a USB host
- Pinguino has an on board Li-Po battery management circuit allowing it to be used as a handheld device
- They added on board microSD for data logging
