RoboPi v1.00

Introduction

RoboPi is the most advanced robot controller add-on board for the Raspberry Pi available at this time.
RoboPi adds an eight-core 32-bit microcontroller running at 100Mhz to the Raspberry Pi in order to
off-load hard real time I/O and allow more precise timing than Linux running on the Pi allows.
RoboPi Features
• Parallax Propeller P8X32 eight core 32 bit Risc microcontroller running at 100Mhz
• Each of the eight cores provides up to 25MIPS as most instructions take only 4 clock cycles
• three ten-pin Mikronauts I/O module expansion connectors (P0-P7, P8-P15, P16-P23)
• 24 servo compatible headers on P0..P23
◦ P0-P7 jumper selectable power from Pi's 5VDC supply or external servo power supply
◦ P8-P15 jumper selectable power from Pi's 5VDC supply or external servo power supply
◦ P16-P23 is powered by 5V from the Pi expansion header for sensors
• Screw terminal for providing external power for Servo connectors P0-P15
• 8 servo compatible headers for an eight channel 0-5V analog to digital converter with choice of
◦ MCP3008 for 10 bit A/D conversion
◦ MCP3208 for 12 bit A/D conversion
• Choice of 256Kbit or 512Kbit boot EEPROM for the Propeller
• On-board voltage regulation providing 3.3V with power on LED from the 5V on the Pi header
• 4 pin I2C expansion header for the Raspberry Pi
• 4 pin I2C expansion header for the Propeller
• 5 pin HCOM connector for use with PropPlug in stand alone operation (optional)
• Mikronauts EZasPi prototyping board can stack below RoboPi
• Mikronauts Pi Jumper can stack on top of RoboPi
• Mikronauts SchoolBoard ][ and other Propeller products are compatible with RoboPi
