RoboProp Controller Board
Mikronauts RoboProp is an advanced eight core 32- bit RISC robot controller with on-board motor
driver, ADC, and up to 32 GB of storage.
RoboProp is the latest in controller boards designed
for students and hobbyists. Unlike conventional robot
controller boards, RoboProp can be programmed with a
native development environment running right on
RoboProp with the addition of an inexpensive video output
/ PS/2 keyboard module and a uSD card pre-loaded with
RoboProp has eight dedicated 12-bit analog inputs,
and 24 I/Os that can be used for servos, digital inputs,
encoders, other Mikronauts I/O and prototyping boards,
an optional on-board L298 dual motor driver, and the on-board SD card. RoboProp also provides separate I2C and
3.3V serial communications ports and two small
RoboProp features include:
* 4.000” x 3.050” standard form factor with standard
mounting hole pattern.
Designed to fit onto a BOEBOT as an upgrade.
Designed to fit Dagu “Mr. Basic” and “Arduino
Motor” robot platforms.
Parallax Propeller processor with eight 32-bit cores
running at 100 MHz.
uSD for data logging and program storage.
L298 full H-bridge driver with up to 2.5A drive with
a large heatsink per motor (3A peak).
Optional current sense resistors.
Eight channel/12-bit ADC for three-pin 5V sensors
Up to 24 channels for servos or digital inputs.
Mikronauts I2C connector for upcoming Mikronauts
HCOMM connector for programming via a Propeller
Plug or Mikronauts SerPlug.
20 SERVO 08.2011
EXP connectors for breadboards and Mikronauts
Can use FlexMem for SRAM/FLASH/FRAM/MRAM
memory expansion (uses 6-8 I/O pins).
Can add the upcoming MCP3208 module for an
additional eight analog input channels (uses four I/O pins).
Can stack on other Mikronauts CPU boards and
breadboards with stacking headers for EXP1/EXP2.
Two small, high density prototype areas.
Screw terminals for Vin/GND, MotorA, and MotorB.
On-board 5V and 3.3V regulation.
RoboPropDiag diagnostic software for testing and
ADC/SERVO/L298 features included:
* Uses OBEX objects for PWM, servos, and ADC.

The new SPG785A- 5.0 servo power gearbox from servocity.com is a
patented rectangular tube
gearbox designed to be
Trading total rotation
for power and
precision is what this
gearbox is all about.
The power plant of the
gearbox is the ultra-popular
Hitec HS-785HB servo which rotates 3. 5 turns right out of
the box. The internal potentiometer provides positioning
feedback which allows the gearbox to perform accurate
and repeatable motions. The user selects a gear ratio that
provides the amount of torque and rotation that best suits
the application. The lower gear ratios provide more
precision and power while the higher ratios offer more
speed and rotation. The dual ABEC- 5 precision ball
bearings and 3/8” stainless steel shaft are able to handle
extreme loads from any direction. The stainless steel shaft
has a .290” bore to allow wires from cameras, sensors,
and other devices to pass through and protect them from
being tangled when operating the gearbox. The rigid 6061
T- 6 aluminum body offers several mounting options so
that the user can mount it in any orientation. Various
attachments can easily be coupled to the aluminum hub
