How Does The Stepper 9 Click Board™ Work?
The Stepper 9 Click Board™ is based on the TB67S581FNG, a two-phase bipolar stepping motor driver designed to control one bipolar stepping motor from Toshiba Semiconductor. The TB67S581FNG supports a PWM constant-current control drive and incorporates low on-resistance DMOS FETs, delivering a 2A maximum current. It can also provide a motor output voltage rating of around 40V and has integrated protection mechanisms such as over-current, over-temperature, and under-voltage lockout for error detection (red LO LED indicator). It supports full-step to 1/32 steps resolution for less motor noise and smoother control, with a built-in regulator that allows the motor to be driven by a single power supply.
The current value in the PWM constant-current mode is set by the reference voltage obtained by the MCP1501, a high-precision voltage regulator. Also, the current threshold point of the TB67S581FNG, alongside MCP1501, can be set manually using an onboard trimmer labelled VREF. The TB67S581FNG supports various step resolution configurations through its control signals. These signals, like step resolution settings, sleep mode, or LO/MO indicators, are controlled through the PCA9538A port expander, which establishes communication with the MCU via the I2C serial interface. In addition to this digital way of setting, these functions can also be selected manually via a multifunctional switch by selecting a particular switch (1,2,3 – Step Resolution Setting; 4 - Decay Mode Control). The PCA9538A also allows choosing the least significant bit (LSB) of its I2C slave address by positioning SMD jumpers labelled as ADDR SEL to an appropriate position marked as 0 and 1, alongside its interrupt feature routed to the INT pin of the mikroBUS™ socket.
The CLK clock signal, routed to the default PWM position on the mikroBUS™ socket, shifts the current step and electrical angle of the motor with its every up-edge, while the Enable pin, labelled as EN and routed to the default CS position, controls the state of the output A and B stepping motor drive channels. Besides, all circuits can be stopped using the Sleep function and thus enable power saving mode. A simple DIR pin routed to the default AN position on the mikroBUS™ socket allows MCU to manage the direction of the stepper motor (clockwise or counterclockwise) while the RST pin initializes an electrical angle in the internal counter to set an initial position. Achieving an initial electrical angle position is indicated via onboard orange LED labelled as MO.
The Stepper 9 Click Board™ supports an external power supply for the TB67S581FNG, which can be connected to the input terminal labelled as VM and should be within the range of 8.2V to 44V, while the stepper motor coils can be connected to the terminals labelled as B+, B-, A-, and A+.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
