• Stacking header for the
• Onboard voltage
3.3V from the 5V on
the Pi header.
• Three screw terminals
• Four-pin 3.3V I2C
• Four-pin 5V I2C expansion header.
• 20-pin header for connecting to a breadboard
can be configured with a choice of the male
header on top for female-to-male jumper wires;
female header on top for using any cut wire or
jumper wire; or a male header on the bottom
for plugging directly into a breadboard.
• Mikronauts EZasPi prototyping board can stack
above and/or below the Pi Jumper.
• Can stack on Mikronauts RoboPi robot
The RoboPi controller adds an eight-core 32-bit
microcontroller running at 100 MHz 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
It’s features include:
• Parallax Propeller P8X32 eight-core 32-bit RISC
microcontroller running at 100 MHz.
• Each of the eight cores provides up to 25 MIPS as
most instructions take only four clock cycles.
• Three 10-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 5 VDC supply or
external servo power supply; P8-P15 jumper
selectable power from Pi's 5 VDC supply or external
servo power supply; and the P16-P23 is powered by
5V from the Pi expansion header for sensors.
• Screw terminal for providing external power for servo
• Eight servo compatible headers for an eight channel
0V-5V analog-to-digital converter with choice of
MCP3008 for 10-bit A/D conversion or MCP3208 for
12-bit A/D conversion.
• Choice of 256 Kbit or 512 Kbit boot EEPROM for the
• Onboard voltage regulation providing 3.3V with
power-on LED from the 5V on the Pi header.
• Four-pin I2C expansion header for the Raspberry Pi.
• Four-pin I2C expansion header for the Propeller.
• Five-pin HCOM connector for use with PropPlug in
stand-alone operation (optional).
• Mikronauts EZasPi prototyping board can stack below
• Mikronauts Pi Jumper can stack on top of RoboPi.
• Mikronauts SchoolBoard (and other Propeller
products) are compatible with RoboPi.
RoboPi is based on Mikronauts RoboProp advanced
robot controller, and when configured to run at 100 MHz
with MCP3208 and 512 Kb of EEPROM, RoboPi can run
RoboProp software that does not require the L298 motor
driver or a microSD card reader present on RoboProp.
Pi Jumper and RoboPi are supplied in kit form in order
to be more cost-effective for schools and individuals. Pricing
is to be announced. Quantity pricing is available for
distributors and educational organizations.
