The Pololu P-Star 25K50 Micro is a general-purpose programmable module based on Microchip's PIC18F25K50 microcontroller, which has 32 KB of flash program memory, 2 KB of RAM, and built-in USB functionality. Onboard features of the P-Star (abbreviated P*) include a 16 MHz crystal, a USB Micro-B connector, and three user-controllable indicator LEDs. A voltage regulator and power selection circuit allow the board to be powered from either USB or an external 5.5 V to 15 V source, while a resettable PTC fuse 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. Features - Dimensions: 1 ? 0.6 (1.05 ? 0.6 including USB Micro-B connector) - Programmable Microchip PIC18F25K50 microcontroller - 32 KB flash (8 KB used by bootloader, leaving 24 KB available for user program by default) 2 KB SRAM - 256 bytes of EEPROM - Native full-speed USB (12 Mbps) - 5 V logic voltage - Internally clocked at 48 MHz, resulting in execution speeds up to 12 million instructions per second (MIPS) - Precision 16 MHz crystal - Many I/O lines in a small package - 16 user I/O lines along the sides of the board - 3 additional I/O pins available in other locations - 13 pins can be configured as analog inputs - 2 PWM output signals (one of which can be sent to four different pins) - 5-bit digital-to-analog converter (DAC) output - Three user-controllable LEDs - USB Micro-B connector - Can be powered from USB or external source regulated to 5 V by onboard regulator - Operating voltage: 5.5 V to 15 V - Can operate down to 3.8 V with decreased logic voltage - Reverse-voltage protection on external power input - PTC fuse on VBUS supply - Ships with a proprietary USB bootloader developed by Pololu for the P-Star - Bootloader is usable from Windows, Linux, and Mac OS X with open source software - No external programmer required - Compatible with standard Microchip compilers, development tools, and programmers - Comprehensive user's guide
