This board is also designed to be connected on any other driver board which could share the
same interface. Power and all signals needed for a power stage board are available on the right
side of the board. Interfaces like USB or Atmel DB101 Display module are also available for
enhanced human interface.

2. Hardware overview
Please refer to schematics, layout and BOM available at http://www.atmel.com.
The MC310 motor control processor board is a ATmega32M1 AVR
®
microcontroller solution con-
nected to a power stage board intended for driving DC motors (Brushless or brushed). All
signals coming from the power stage board are connected to the microcontroller either directly
or through jumpers for sensorless or sensor configuration. External comparators present on the
board allow for the sensorless control mode with this particular ATmega32M1.
A potentiometer can control speed and rotation direction of the motor.
A UART to USB bridge is available to transfer motor control status & commands to a PC soft-
ware interface: Atmel Motor Control Center.
Three 2,54mm headers are available to add the Atmel DB101 Display module in order to
enhance visualization of motor control data & commands.
Three 8-pin & one 16-pin 2,54mm (100mil) horizontal male pin headers on the right side of the
board form a system connector for the power boards like MC300.
Both microcontrollers: ATmega32M1 & AT90USB1287 have their own debug/ISP interface for
user’s specific developments.
Test points either mounted or not, are also available for instrumentation.
