MOTOR-2 simultaneously controls two bipolar or unipolar stepping motors with phase currents up to 2.5A. Featuring an Atmel ATmega168V AVR microcontroller and an Allegro A3979 stepper motor IC, MOTOR-2 can be used as a stand-alone microcontroller board or as a motor controller peripheral board.
Six control pins and 5V power supply connections are available on a 20-pin (2×10) expansion connector. This board can be connected either in piggyback using standoffs or can be placed away using a 20-wire ribbon cable.
As a peripheral, the board's expansion connector is plug-in compatible with MicroTRAK, MINI-MAX and BSCB systems. You can use it in your own system too, of course; see the manual for the expansion connector's pinout.
As a standalone ATmega168 system, the same expansion connector can be used to add your own peripheral devices to this board. There's also a 10-pin connector for the AVR's RS232 port. In-system programming of the ATmega168 is supported through a 6-pin SPI port connector with standard AVR ISP pinout.
Motor Control Board Features
- Atmel ATmega168V-10 microcontroller with 16 Kbytes on-chip Flash program/data Memory, 1 Kbytes RAM, 512 bytes EEPROM
- SPI Port connector for In-circuit Programming and for data communications
- RS232 Serial Port for data communications
- 10-pin terminal block to connect four stepper motor wings and a motor power source
- 20-pin Expansion connector for peripheral boards or a host microcontroller board
- Jumper blocks to select a work mode
- Two push-button switches to drive the motor by hand
- Single operating voltage: 12V to 35V DC (up to 2.5A) for stand-alone operations
- Secondary operating voltage: 4.5V to 5.5V, 130 mA maximum supply consumption for coupled operations
- On-board 5V regulator
If you want to chain multiple add-on boards together, you can purchase cable and connectors separately to construct daisy-chain cables that suit your setup.
