• Kit Pinguino 45K50

Easy-to-build, easy-to-use and very powerful.

The Pinguino 45K50 is one of the most simple board to assemble.

It is little (71x26mm) but very easy to solder even for kids.

It needs only 4 resistors, 3 capacitors, 2 LEDs, 1 reset button and 1 USB connector (as every Pinguino is a full-speed USB device) to work.

The Pinguino 45K50 is also an upgradeable board.

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).

Building instructions are available on the Wiki.
