Hardware Overview
How does it work?
H-Bridge 4 Click is based on the AP1010AEN, a two-channel H-Bridge motor driver from AKM Semiconductor compatible with motor operating voltage up to. This IC is an efficient integrated H-bridge driver with low RDS ON output per switch. H-bridge, in general, allows the current to flow in one or another direction. The output stages consist of four n-channel MOSFETs in an H-bridge configuration. The outputs are protected against short circuits and over-temperature. The bridge is controlled using the inputs IN1, IN2, IN3, and IN4, routed to the AN, RST, INT, and PWM pins on
the mikroBUS™, respectively. Its motor operating voltage range is between 6V～18V, and the control power supply is unnecessary. Its maximum output current (DC) is 0.7A @Ta=25°C and has H-Bridge On-Resistance, which equals RON(TOP+BOT) = 1.1Ω @Ta=25°C. The Click board™ has an onboard motor supply voltage selection switch, although using the external power supply is recommended. The AP1010AEN also has a parallel connection undervoltage lockout and thermal shutdown circuits. When the current of 2.6A or more continues to flow to the
H-Bridge driver for 10μs, all H-Bridge driver outputs are set to Hi-Z and automatically return after 200ms. This Click board™ can operate with either 3.3V or 5V logic voltage levels. 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
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.

Accessories
DC Gear Motor - 430RPM (3-6V) represents an all-in-one combination of a motor and gearbox, where the addition of gear leads to a reduction of motor speed while increasing the torque output. This gear motor has a spur gearbox, making it a highly reliable solution for applications with lower torque and speed requirements. The most critical parameters for gear motors are speed, torque, and efficiency, which are, in this case, 520RPM with no load and 430RPM at maximum efficiency, alongside a current of 60mA and a torque of 50g.cm. Rated for a 3-6V operational voltage range and clockwise/counterclockwise rotation direction, this motor represents an excellent solution for many functions initially performed by brushed DC motors in robotics, medical equipment, electric door locks, and much more.

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.

*
* # Description
* This application is used to turn on DC or Stepper motors.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initialization driver enables GPIO and also starts write log.
*
* ## Application Task
* This example demonstrates the use of H-Bridge 4 click board by putting A motor
* in standby mode, then spining it in clockwise direction and applying brake function, and then
* spining it in counter-clockwise direction and applying brake function again.
