Product Description

Up for sale is an I2C controlled AMIS30624 breakout board.  This board uses the I2C serial interface to control and drive stepper motor motion, including adjusting speed, current, and aceleration and deceleration ramps.  The motor controller takes care of most software stepper controller code, and leaves you with high level functions to operate with.  See the data sheet to read more about its advanced functions.
 
Note:  An economical, compatible 12V stepper motor is now available in my store!
Features:
- Small form factor:  45x25mm
- 8 to 29V motor power
- TTL command voltage
- Up to 800mA motor power per coil
- I2C serial interface with simple command structure
- Addresses assignable via I2C interface
- Includes header pin for signal connection
- Power on indicator LED
- Screw terminals for motor power and motor output
- Standoff scew holes for mounting purposes
 
From the manufacturer:
The AMIS-30624 is a single chip micro-stepping motor driver with a position controller and control/diagnostic interface. It is ready to build intelligent peripheral systems where up to 32 drivers can be connected to one I2C master. This significantly reduces system complexity.
The device receives positioning instructions through the bus and subsequently drives the stator coils so the two-phase stepper motor moves to the desired position. The on-chip position controller is configurable (OTP or RAM) for different motor types, positioning ranges and parameters for speed, acceleration and deceleration. Micro-stepping allows silent motor operation and increased positioning resolution. The advanced motion qualification mode enables verification of the complete mechanical system in function of the selected motion parameters. The AMIS-30624 can easily be connected to an I2C bus where the I2C master can fetch specific status information like actual position, error flags, etc. from each individual slave node.
An integrated sensorless stall detection stops the motor when running into stall. This enables silent, yet accurate position calibrations during a referencing run and allows semi-closed loop operation when approaching the mechanical end-stops.
The device is implemented in I2T100 technology, enabling both high voltage analog circuitry and digital functionality on the same chip. The AMIS-30624 is fully compatible with the automotive voltage requirements.
