Hardware Overview
How does it work?
Tilt 5 Click is based on the RBS240100T, a ball-contact tilt sensor switch from OncQue designed to provide precise tilt detection in various applications. This Click board™ uses the capabilities of the RBS240100T sensor, which reliably detects a 45° tilt within a full 360° radius, making it a highly versatile solution for motion-based triggering and orientation sensing. The sensor operates in a normally open switch state, ensuring low power consumption until a tilt event is detected. It offers exceptional electrical performance and reliability with a contact resistance of just 50mΩ and an insulation resistance of 50MΩ. The RBS240100T can also handle a maximum contact current of 10mA, making it suitable for a wide range of low-power and energy-efficient applications. This Click board™ is ideal for security and safety systems,
such as anti-theft and anti-tamper devices, where detecting unauthorized movement is crucial. It is also well-suited for alarm systems, earthquake detection units, and wake-up mechanisms designed to optimize power consumption by activating only when movement is detected. This Click board™ is designed in a unique format supporting the newly introduced MIKROE feature called "Click Snap." Unlike the standardized version of Click boards, this feature allows the main sensor area to become movable by breaking the PCB, opening up many new possibilities for implementation. Thanks to the Snap feature, the RBS240100T can operate autonomously by accessing its signals directly on the pins marked 1-8. Additionally, the Snap part includes a specified and fixed screw hole position, enabling users to secure the Snap board in their desired location. Tilt 5 Click uses a single INT pin
as its primary connection to the host MCU, serving as the tilt detection signal. When a tilt event is detected, the sensor generates a signal through the INT pin, which is then processed by the host MCU for further action. In addition to the INT pin, the board features an orange LD2 LED that visually indicates tilt detection, ensuring real-time feedback for users and enhancing its practicality in various applications. 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
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.

Software Support
Library Description
Tilt 5 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.
Example Description
This example demonstrates the use of the Tilt 5 Click, which detects tilt motion using a ball switch sensor. The example initializes the device and continuously monitors the tilt state, logging changes between active and idle states.
Key functions:
tilt5_cfg_setup- This function initializes Click configuration structure to initial values.tilt5_init- This function initializes all necessary pins and peripherals used for this Click board.tilt5_get_out_pin- This function returns the OUT pin logic state.
Application Init
Initializes the logger and configures the Tilt 5 Click.
Application Task
Continuously reads the tilt state and logs changes. The state toggles between "ACTIVE" when a tilt is detected and "IDLE" when the sensor is in its default position.
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.
