The Pinguino 45K50 is now available as a Kit in the Pinguino Shop for 9.90 € (inc. VAT).
This new Pinguino is based on the PIC18F45K50 which is pin to pin comparable with the older 4550 serie, and is also capable of running at 5V. It also features a USB precision integrated oscillator, enabling you to build USB projects without the need of any external oscillator, and a CTMU unit for measurement applications.
The Pinguino 45K50 is also very easy to build as it needs only few components (4 resistors, 3 capacitors, 2 LEDs, 1 reset button and 1 USB connector) to work.
The PCB has been designed to be upgradeable. If you need it, you can add a 5V regulator to feed the board from an external power supply. It’s also possible to add an external crystal. In this case, note that the PCB is fully compatible with the PIC18F4550 so you can easily turn your Pinguino 45K50 to a Pinguino 4550.
The Pinguino 45K50 comes pre-programmed with a USB bootloader, so you won’t even need a programmer to use it. You only need a USB cable and a computer (PC or Raspberry Pi).
