Hardware Overview
How does it work?
DC Motor 23 Click is based on the TB67H480FNG, a dual-channel, H-bridge, brushed DC motor driver from Toshiba Semiconductor. The TB67H480FNG has a current limit function that monitors the current flowing in the motor. When the motor current reaches the set current value, determined using onboard VREF trimmers (VREFA and VREFB), it shifts to Decay mode, selectable by positioning the SMD jumper labeled as DECAY to an appropriate position marked as 0 and 1, for a fixed OFF time and attenuates the current. The TB67H480FNG has a built-in regulator that allows the motor to be driven by a single power supply, provides 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. The setting current value can be adjusted with the torque function (100%, 71%, 38%,
or 0%), controlled through the PCA9538A port expander, which establishes communication with the MCU via the I2C serial interface. Lowering the torque setting can suppress the motor current when high torque is unnecessary. In addition to these torque setting pins, with the help of the expander, it is also possible to control some other signals, such as the control signals for selecting the operating mode of the motor driver. These pins, in combination with ENA and ENB pins, routed to default positions of CS and PWM pins of the mikroBUS™ socket, enable operational modes like CW, CCW, or short-brake. The PCA9538A also allows choosing the least significant bit (LSB) of its I2C slave address by positioning SMD jumpers labeled 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. Besides, all circuits can be stopped using the
Sleep function, routed to default positions of the AN pin of the mikroBUS™ socket, and thus enable power saving mode, while the RST pin provides a general-purpose reset function. The DC Motor 23 Click supports an external power supply for the TB67H480FNG, which can be connected to the input terminal labeled as VM and should be within the range of 8.2V to 44V, while the two brushed or one stepping motor coils can be connected to the terminals labeled 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. 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
Flip&Click PIC32MZ is a compact development board designed as a complete solution that brings the flexibility of add-on Click boards™ to your favorite microcontroller, making it a perfect starter kit for implementing your ideas. It comes with an onboard 32-bit PIC32MZ microcontroller, the PIC32MZ2048EFH100 from Microchip, four mikroBUS™ sockets for Click board™ connectivity, two USB connectors, LED indicators, buttons, debugger/programmer connectors, and two headers compatible with Arduino-UNO pinout. Thanks to innovative manufacturing technology,
it allows you to build gadgets with unique functionalities and features quickly. Each part of the Flip&Click PIC32MZ development kit contains the components necessary for the most efficient operation of the same board. In addition, there is the possibility of choosing the Flip&Click PIC32MZ programming method, using the chipKIT bootloader (Arduino-style development environment) or our USB HID bootloader using mikroC, mikroBasic, and mikroPascal for PIC32. This kit includes a clean and regulated power supply block through the USB Type-C (USB-C) connector. All communication
methods that mikroBUS™ itself supports are on this board, including the well-established mikroBUS™ socket, user-configurable buttons, and LED indicators. Flip&Click PIC32MZ development kit allows you to create a new application in minutes. Natively supported by Mikroe software tools, it covers many aspects of prototyping 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 via Debug Mode
1. Once the code example is loaded, pressing the "DEBUG" button initiates the build process, programs it on the created setup, and enters Debug mode.
2. After the programming is completed, a header with buttons for various actions within the IDE becomes visible. Clicking the green "PLAY" button starts reading the results achieved with the Click board™. The achieved results are displayed in the Application Output tab.

* @file main.c
* @brief DC Motor 23 Click example
*
* # Description
* This example demonstrates the use of DC Motor 23 click board™.
* by driving the motors in both direction every 3 seconds.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initializes the driver and performs the click default configuration
* which sets the output torque to 100%.
*
* ## Application Task
* This example demonstrates the use of the DC Motor 23 Click board™.
* Drives the motors in the clockwise direction,
* after that decay the motors with a 3 seconds delay
* then switches to the counter-clockwise direction,
* and decay the motors with a 3 seconds delay.
* Results are being sent to the UART Terminal, where you can track their changes.
