Hardware Overview
How does it work?
Relay 4 Click is based on dual J1031C3VDC, high-current single-pole double-throw (SPDT) signal relays from CIT Relay and Switch. The J1031C3VDC relay is well known for its reliability and durability, high sensitivity, and low coil power consumption housed in a small package with PC pin mounting. Despite its size (12.5x7.5x10 millimeter (LxWxH)), the J1031C3VDC relay can withstand up to 2A and 125VAC/60VDC maximum. These relays are designed to easily activate their coils by relatively low currents and voltages, making them a perfect choice that any MCU can control. As mentioned, the contact configuration of the J1031C3VDC is a single-pole double-throw (SPDT), meaning it
has one pole and two throws. Based on the default position of the pole, one throw is considered normally open (NO) while the other is normally closed (NC), which is, in this case, its default position. When the coil is energized, it will attract the internal switching elements similar to a switch. This Click board™ uses two mikroBUS™ pins for its proper operation, the RL1 and RL2 pins routed to the RST and PWM pins of the mikroBUS™ socket. These pins control small N-channel MOSFET RET (Resistor Equipped Transistor) transistors that provide enough current for the relay coil. Two resistors are already integrated into the RET, providing the correct biasing and simplifying the
design. Also, each relay has its yellow LED indicator, which signals the state of the relay. When the current flows through the RET, the coil will be energized, and the relay will be switched from a closed to an open switch state. This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it comes equipped with a library containing functions and an example code that can be used as a reference for further development.
Features overview
Development board
Clicker 2 for Kinetis is a compact starter development board 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 ARM Cortex-M4F microcontroller, the MK64FN1M0VDC12 from NXP Semiconductors, two mikroBUS™ sockets for Click board™ connectivity, a USB connector, LED indicators, buttons, a JTAG programmer connector, and two 26-pin headers for interfacing with external electronics. Its compact design with clear and easily recognizable silkscreen markings allows you to build gadgets with unique functionalities and
features quickly. Each part of the Clicker 2 for Kinetis development kit contains the components necessary for the most efficient operation of the same board. In addition to the possibility of choosing the Clicker 2 for Kinetis programming method, using a USB HID mikroBootloader or an external mikroProg connector for Kinetis programmer, the Clicker 2 board also includes a clean and regulated power supply module for the development kit. It provides two ways of board-powering; through the USB Micro-B cable, where onboard voltage regulators provide the appropriate voltage levels to each component on the board, or
using a Li-Polymer battery via an onboard battery connector. All communication methods that mikroBUS™ itself supports are on this board, including the well-established mikroBUS™ socket, reset button, and several user-configurable buttons and LED indicators. Clicker 2 for Kinetis is an integral part of the Mikroe ecosystem, allowing 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.

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.
Software Support
Library Description
This library contains API for Relay 4 Click driver.
Key functions:
relay4_set_relay1_open- This function sets the relay 1 to normally open state by setting the RL1 pin to low logic level.relay4_set_relay1_close- This function sets the relay 1 to normally close state by setting the RL1 pin to high logic level.relay4_set_relay2_open- This function sets the relay 2 to normally open state by setting the RL2 pin to low logic level.

* # Description
* This example demonstrates the use of Relay 4 click board by toggling the relays state.
*
* The demo application is composed of two sections :
*
* ## Application Init
* Initializes the driver and logger.
*
* ## Application Task
* Switches the relays 1 and 2 state every 5 seconds and displays the state on the USB UART.
