Status:
Opto 7 Click is a compact add-on board that provides uncomplicated safety isolation from high voltage. This board features two ISOM8710, high-speed single-channel opto-emulators from Texas Instruments. The ISOM8710 opto-emulator has a diode-emulator input and digital output. It has a robust isolation barrier capable of withstanding up to 3750VRMS and a surge capability of up to 10KV. This Click board™ makes the perfect solution for the development of power supplies, grids, electricity meters, motor drives, factory automation and control, building automation, and more.
Opto 7 Click is fully compatible with the mikroBUS™ socket and can be used on any host system supporting the mikroBUS™ standard. It comes with the mikroSDK open-source libraries, offering unparalleled flexibility for evaluation and customization. What sets this Click board™ apart is the groundbreaking ClickID feature, enabling your host system to seamlessly and automatically detect and identify this add-on board.

Availability date:
Opto 7 Click is based on two ISOM8710s, high-speed single-channel opto-emulators from Texas Instruments. It can transmit data rates of up to 25Mbps and can output 3.3V and 5V signals with a CMOS-compatible output. Compared to an optocoupler, the ISOM7810 has a high common mode transient immunity, low propagation delay, small pulse with distortion, low power consumption, and more. Opto 7 Click is equipped with two of those opto-emulators, for receiving and transmitting data. The external power supply can be connected to a VCC2 terminal and must be 3.3V or 5V. The three-pin terminal is used to connect input and output data lines, along with the common ground.
Opto 7 Click can use general-purpose IO to communicate with the host MCU over the GP1 and GP2 pins. It can also be used for a standard UART communication isolation with commonly used UART RX and TX pins. The selection can be made over the OUT SEL and IN SEL jumpers. Both should be in a proper position for the communication to work.
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.

Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MIKROE compilers.
This Click board™ is supported with mikroSDK - MIKROE Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
For more information about mikroSDK, visit the official page.
NOTE: Please be advised that any peripheral devices or accessories shown connected to the Click board™ are not included in the package. Check their availability in our shop or in the YMAN section below.
