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.
Our comprehensive user’s guide provides the basics you need to get started with the P-Star as well as detailed technical information.
This product requires a USB A to Micro-B cable (not included) to connect to a computer.

Notes:
- 1 Without included optional headers. This measurement includes the USB Micro-B connector, which extends 0.05″ past the edge of the PCB.
- 2 Without included optional headers.
- 3 8 KB of the MCU's 32 KB of flash memory is used by the pre-installed USB bootloader. All 32 KB is available if you use an external programmer and erase the bootloader.
- 4 All 30 can be used as digital I/O, 25 can be used as analog inputs, and one can be an analog output. 28 of the 30 are available along the sides for use in a breadboard.
- 5 For light loads. The regulator's dropout voltage increases approximately linearly with the load, from a few millivolts at no load up to around 0.6 V at 500 mA.
- 6 On BAT+.
