P-Star Programmable Controllers
P-Star 25K50 Micro (top) and P-Star 45K50 Mini SV (bottom).
The Pololu P-Star microcontroller boards are a family of general-purpose programmable modules based on the PIC18F25K50 and PIC18F45K50 microcontrollers from Microchip, which have 32 KB of flash program memory, 2 KB of RAM, and built-in full-speed USB functionality. The P-Stars add on-board components and connectors that support the microcontroller and make it easier to use. Each board ships with a USB bootloader that makes it easy to load new programs without using an external programmer.
