Servo/Sensor/Motor Interface Board
for NanoCore12DX™
Data Sheet
Description
Designed primarily for robotics and mechatronics
applications. this module provides a wide range of features
that a user would need to realize these applications using a
NanoCore12DX microcontroller module. Support for hobby
R/C servos, DC motors, and IR and sonar
distance-measuring sensors are the primary features. A
generous solderless breadboard section is provided for
additional circuits and experiments that the user may wish to
design. Both 3V and 5V operation is supported, via the
on-board adjustable regulator, and the power source can be
wall-powered or battery-powered. For battery-powered
applications, a battery voltage monitoring circuit is
implemented. Both a microphone and audio transducer are
provided to enable interactive applications.
Detailed Feature List:
• four analog sensor connectors, can be used with IR distance-measuring sensors, accelerometers, etc.
• six connectors for hobby servos (implemented on Port T of the MCU, to enable PWM control)
• one 9-pin serial port connector for programming and communications
• two connectors for Devantech SRF04 Analog Ultrasonic Ranger
• separate 6 Volt regulator for servos (isolates electrical noise and provides increased torque)
• separate 5 Volt regulator for analog sensors (isolates electrical noise)
• battery voltage monitoring (up to 20volts)
• audio transducer
• microphone so your robot can detect sound
• dual high-current H-bridges (4A continuous, 6A peak)
• convenient pluggable terminal blocks for motor and power connections
• solderless breadboard for customized hardware design
• same mounting hole locations as NanoCore12 School Board (compatible with most hobby robot bases)
• requires 32-pin NanoCore module (#NC12DXC32)
• supplied with schematic and datasheet

*Note: to use higher voltage motors (e.g. 12V or 24V), remove L1 and L2, and supply Vin
to MCU module separately (maximum 12V), via pin 32 on H1 or H2. Then motor voltage
may be safely applied via J5.
