Status:
Brushless 13 Click is a compact add-on board that controls brushless DC motors with any MCU. This board features the STSPIN830, a compact and versatile three-phase and three-sense motor driver from STMicroelectronics. The driver integrates both the control logic and a fully protected low RDson triple half-bridge power stage. On this Click board™, the single-shunt architecture is enabled, and the driver embeds a PWM current limiter based on user-settable values of reference voltage and OFF time. This Click board™ makes the perfect solution for the development of industrial robotics, medical and health care, factory automation end-points, home appliances, small pumps, and more.
Brushless 13 Click is fully compatible with the mikroBUS™ socket and can be used on any host system supporting the mikroBUS™ standard. It comes with the mikroSDK open-source libraries, offering unparalleled flexibility for evaluation and customization. What sets this Click board™ apart is the groundbreaking ClickID feature, enabling your host system to seamlessly and automatically detect and identify this add-on board.

Brushless 13 Click is based on the STSPIN830, a compact and versatile three-phase and three-sense motor driver from STMicroelectronics. The driver features the dedicated mode input, thus allowing you to decide whether to drive it through six inputs, one for each power switch or a more common three PWM direct driving inputs. The driver integrates a complete set of protections for the power stages, such as non-dissipative overcurrent, thermal shutdown, short-circuit, under-voltage lockout, and interlocking. Considering a low standby current consumption, it makes an ideal and bulletproof solution for the new wave of demanding industrial applications.
To control all high and low side driver control inputs of the STSPIN830, Brushless 13 Click features the PCA9538A, a low-voltage 8-bit I2C I/O port with interrupt and reset from NXP. Besides driver control inputs, this I/O port also controls the enable input of the motor driver. The BLDC motor can be connected over the screw terminal, labeled U, V, and W. Additional screw terminal is just aside for connecting an external power supply in a range of 7V up to 45V.
Brushless 13 Click uses a standard 2-wire I2C interface of the PCA9538A to communicate with the host MCU, supporting clock frequencies up to 400kHz. The I2C address of the PCA9538A can be set over the ADDR SEL jumpers, with the 0 position selected by default. If a fault condition occurs, the STSPIN830 will pull the FLT pin to a low logic state, along with the FAULT LED. The RST pin resets the STSPIN830 motor driver. The driver's mode can be set over the MOD pin, with a HIGH logic state for three PWM direct drive inputs. The LOW logic state will allow a driver to drive the motor through six inputs.
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. Also, this 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.

Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MIKROE compilers.
This Click board™ is supported with mikroSDK - MIKROE Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
For more information about mikroSDK, visit the official page.
NOTE: Please be advised that any peripheral devices or accessories shown connected to the Click board™ are not included in the package. Check their availability in our shop or in the YMAN section below.
