STMicroelectronics X-NUCLEO-IHM02A1 Motor Driver Expansion Board

STMicroelectronics X-NUCLEO-IHM02A1 Two-Axis Stepper Motor Driver Expansion Board is based on the L6470. The STMicroelectronics board provides an affordable and easy-to-use solution for low-voltage motor control driving for stepper motors.

The expansion board includes two L6470s, and a fully integrated micro-stepping motor driver to control stepper motors using high-end motion control commands received through SPI. The board can drive one or two stepper motors when plugged into an STM32 Nucleo board.

Features

Operating voltage: 8V - 45V DC
7A peak output current (3 A rms) for each motor driver
3.3V digital voltage supply may be provided by
- the STM32 Nucleoboard
- the step-down monolithic power switching regulator soldered on the expansion board (through jumper selection, it can also be used to supply the STM32 Nucleo board
USART communication
- enables receiving of commands from a PC
- enables sending information to a PC
- Requires no dedicated cable; uses the Type A to Type Mini-B USB cable already used to supply the STM32 Nucleo board

Digital voltage supply is selectable (3.3V or 5.0V) by a 0Ω resistor and is provided on the main board
SPI interface (may be connected in a daisy chain configuration)
Equipped with Arduino UNO R3 connectors
Layout compatible with ST morpho connectors
Five LEDs
- 2 green to indicate that each L6470 is powered
- 1 orange to indicate that the digital voltage is on
- 1 yellow to indicate when any L6470 is busy
- 1 red to indicate when a fault condition occurs (step loss, OCD, thermal pre-warning or shutdown, UVLO, incorrect command, non-performable command) for any L6470
RoHS compliant
