Overview

The Pololu P-Star 45K50 Mini SV is a general-purpose programmable module based on Microchip?s PIC18F45K50 microcontroller, which has 32 KB of flash program memory, 2 KB of RAM, and built-in USB functionality. On-board features of the P-Star (abbreviated P*) include a 16 MHz crystal, a USB Micro-B connector, and three user-controllable indicator LEDs. A switching step-down voltage regulator and power selection circuit allow the board to be powered from either USB or an external 5 V to 36 V source, while a current limit on the USB VBUS supply and reverse protection on VIN help protect it from accidental damage. The board ships with a USB bootloader that makes it easy to program the PIC microcontroller without using an external programmer.

This product requires a USB A to Micro-B cable (not included) to connect to a computer.
