PCA9629APW stepping motor driver breakout board

This board has PCA9629APW, the stepping motor controller IC by NXP, soldered onto a breakout board.Output wave train is programmable using control registers. The control registers are programmed via the I²C-bus.

This board is an IC controller and does not have a motor driver. Please choose an appropriate driver on your own.

Spec

  • Operating voltage: 4.5 V ~ 5.5 V.
  • Controls four Unipolar stepping motor coils
  • Four balanced push-pull type outputs capable of sinking 25 mA or sourcing 25 mA
  • One-phase (wave drive), two-phase, and half-step drive format logic level outputs
  • Programmable motor action either multiple times (1 to 255) or continuously
  • Programmable re-start motor with new speed and operation while motor is still running
  • Programmable ramp-up on start and ramp-down to stop
  • 32-bit step counter to count output steps
  • Programmable watchdog timer with option to generate interrupt, reset device or stop motor
  • Four general purpose I/Os: P0 to P3
  • A variety of interrupting features from IC
  • Interface: I2C
  • I2 address: 0 × 40 (0100 000x) ~ 0 × 5E (0101 111x)
  • A pattern signal on pull-up resistor for I2. (resistor is not included)

Cautions

  • About pinheader
    Please prepare the pin header by yourself and solder it depending on your purpose.

  • About pull-up resistor for I2C.
    The pull-up resistor for I2C is not included at default. If you are thinking of adding, please solder chip resistor to R1 and R2 on back of board (chip size: 1608). When doing this, please be advised to assemble chip resistor first, because the distance between chip resistor and pin header is close.

  • About I2C address
    Default address is 0 × 44 (0100 010X) according to solder jumper (AD1, AD0) on back of board.
    You can change I2C address by processing solder jumper as shown on below chart.
