Hardware Overview

How does it work?

Brushless 20 Click is based on the DRV8313, a fully integrated three-phase BLDC motor driver from Texas Instruments. The highly integrated DRV8313 comes with PWM/enable control interface, a wide voltage operating range, an integrated 10mA LDO, and robust on-chip protection features. Low RDSON and efficient switching algorithms ensure excellent thermal performance and high drive capability. This Click board™ offers an energy-saving solution and quiet motor operation for brushless DC (BLDC) motors used in various applications. Each output driver channel comprises N-channel power MOSFETs configured in a 1/2-H-bridge configuration. Control pins can be accessed through the I2C interface

and the PCA9538A port expander, with which the states of those pins, alongside the state of the output terminals, can be directly controlled. The PCA9538A also allows choosing the least significant bit (LSB) of its I2C slave address by positioning SMD jumpers labeled ADDR SEL to an appropriate position marked as 0 and 1, alongside its interrupt and Reset features routed to the INT and RST pins of the mikroBUS™ socket. The DRV8313 is active unless the SLP pin, routed to the CS pin of the mikroBUS™ socket, is brought to a low logic state. The charge pump and output FETs are disabled in sleep mode alongside the internal LDO regulator. The DRV313 is automatically brought out of sleep mode if SLP is in a logic high state.

This board also supports an external power supply for the motor, which can be connected to the input terminal labeled as VM and should be within the range of 8V to 60V, while the BLDC motor coils can be connected to the terminals labeled as 1, 2, and 3. 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.

Features overview

Development board

Clicker 4 for STM32F3 is a compact development board designed as a complete solution, you can use it to quickly build your own gadgets with unique functionalities. Featuring a STM32F302VCT6, four mikroBUS™ sockets for Click boards™ connectivity, power managment, and more, it represents a perfect solution for the rapid development of many different types of applications. At its core, there is a STM32F302VCT6 MCU, a powerful microcontroller by STMicroelectronics, based on the high-

performance Arm® Cortex®-M4 32-bit processor core operating at up to 168 MHz frequency. It provides sufficient processing power for the most demanding tasks, allowing Clicker 4 to adapt to any specific application requirements. Besides two 1x20 pin headers, four improved mikroBUS™ sockets represent the most distinctive connectivity feature, allowing access to a huge base of Click boards™, growing on a daily basis. Each section of Clicker 4 is clearly marked, offering an intuitive and clean interface. This makes working with the development

board much simpler and thus, faster. The usability of Clicker 4 doesn’t end with its ability to accelerate the prototyping and application development stages: it is designed as a complete solution which can be implemented directly into any project, with no additional hardware modifications required. Four mounting holes [4.2mm/0.165”] at all four corners allow simple installation by using mounting screws. For most applications, a nice stylish casing is all that is needed to turn the Clicker 4 development board into a fully functional, custom design.

Library Description

This library contains API for Brushless 20 Click driver.

Key functions:

brushless20_perform_com_sequenceThis function performs a single commutation sequence at a desired speed for the selected rotation direction.
brushless20_drive_motor This function drives the motor for a desired time by performing multiple commutation sequences for the selected rotation direction at a desired speed.
brushless20_get_fault_pin This function returns the fault pin logic state.

Open Source

Code example

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.

 * @brief Brushless 20 Click example
 *
 * # Description
 * This example demonstrates the use of the Brushless 20 Click board by driving the 
 * motor in both directions at different speeds.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Drives the motor in both directions and changes the motor speed every 3 seconds approximately.
 * The current driving direction and speed will be displayed on the USB UART.
