Hardware Overview
How does it work?
Cooler Click is based on the DRV8213, an advanced brushless DC motor driver from Texas Instruments, as its core component. This innovative board integrates a miniature temperature sensor, TMP007, and a cooling fan, MF25060V2-1000U-A99, right on its surface, making it a ready-to-go cooling solution. It's perfectly suited for use in environments prone to overheating, such as server rack cooling, embedded systems and IoT devices, development board prototyping, gaming consoles and PC cooling, automotive electronics, medical equipment cooling, or similar applications, where continuous cooling is essential. The DRV8213 is a comprehensive motor driver featuring an integrated full-bridge driver with current sensing and regulation capabilities and a unique current sense output. It's designed for efficiency, using a 2-pin PWM interface for motor speed control through the
IN1 and IN2 pins on the mikroBUS™ socket, covering a wide PWM frequency range from 0 to 100kHz. Notably, its auto-sleep mode reduces the need for additional GPIO connections for sleep or turn-off functions by automatically entering a low-power mode when not in use. The DRV8213 is also enriched with several protection features, such as undervoltage lockout, overcurrent protection, and overtemperature shutdown, ensuring reliable operation under various conditions. The TMP007 sensor, another onboard component from Texas Instruments, employs infrared thermopile technology to measure temperatures without direct contact with the object. This capability accurately monitors the surrounding temperature where the Click board™ is placed. The sensor's output is digitized and processed along with the die temperature to compute the object temperature. It
uses an I2C interface for communication with the host MCU and an alert function via the ALR pin of the mikroBUS™ socket for temperature exceedance notifications. Complementing these components is the MF25060V2-1000U-A99 fan, a high-performance cooling fan operating on a 5VDC supply capable of reaching speeds up to 10,000 RPM. This fan is essential for dissipating heat efficiently, ensuring the system remains cool under operation. 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.
Features overview
Development board
Fusion for TIVA v8 is a development board specially designed for the needs of rapid development of embedded applications. It supports a wide range of microcontrollers, such as different 32-bit ARM® Cortex®-M based MCUs from Texas Instruments, regardless of their number of pins, and a broad set of unique functions, such as the first-ever embedded debugger/programmer over a WiFi network. The development board is well organized and designed so that the end-user has all the necessary elements, such as switches, buttons, indicators, connectors, and others, in one place. Thanks to innovative manufacturing technology, Fusion for TIVA v8 provides a fluid and immersive working experience, allowing access
anywhere and under any circumstances at any time. Each part of the Fusion for TIVA v8 development board contains the components necessary for the most efficient operation of the same board. An advanced integrated CODEGRIP programmer/debugger module offers many valuable programming/debugging options, including support for JTAG, SWD, and SWO Trace (Single Wire Output)), and seamless integration with the Mikroe software environment. Besides, it also includes a clean and regulated power supply module for the development board. It can use a wide range of external power sources, including a battery, an external 12V power supply, and a power source via the USB Type-C (USB-C) connector.
Communication options such as USB-UART, USB HOST/DEVICE, CAN (on the MCU card, if supported), and Ethernet is also included. In addition, it also has the well-established mikroBUS™ standard, a standardized socket for the MCU card (SiBRAIN standard), and two display options for the TFT board line of products and character-based LCD. Fusion for TIVA v8 is an integral part of the Mikroe ecosystem for rapid development. Natively supported by Mikroe software tools, it covers many aspects of prototyping and development thanks to a considerable number of different Click boards™ (over a thousand boards), the number of which is growing every day.

Application Output
1. Application Output - In Debug mode, the 'Application Output' window enables real-time data monitoring, offering direct insight into execution results. Ensure proper data display by configuring the environment correctly using the provided tutorial.
2. UART Terminal - Use the UART Terminal to monitor data transmission via a USB to UART converter, allowing direct communication between the Click board™ and your development system. Configure the baud rate and other serial settings according to your project's requirements to ensure proper functionality. For step-by-step setup instructions, refer to the provided tutorial.
3. Plot Output - The Plot feature offers a powerful way to visualize real-time sensor data, enabling trend analysis, debugging, and comparison of multiple data points. To set it up correctly, follow the provided tutorial, which includes a step-by-step example of using the Plot feature to display Click board™ readings. To use the Plot feature in your code, use the function: plot(*insert_graph_name*, variable_name);. This is a general format, and it is up to the user to replace 'insert_graph_name' with the actual graph name and 'variable_name' with the parameter to be displayed.
Software Support

/*!
* @file main.c
* @brief Cooler Click Example.
*
* # Description
* This example demonstrates the use of the Cooler click board
* by reading the target object temperature and controlling the cooler.
*
* The demo application is composed of two sections :
*
* ## Application Init
* The initialization of the I2C module, log UART, and additional pins.
* After the driver init, the app executes a default configuration.
*
* ## Application Task
* The demo application measures the temperature of the target object in degrees Celsius
* and enables a cooler if the temperature exceeds the temperature high limit value.
* Results are being sent to the UART Terminal, where you can track their changes.
