Status:
IR Beacon Click is a compact add-on board that provides a beaconing capability to your application. This board features nine VSMB2948SLs, high-speed infrared emitting diodes from Vishay Semiconductors. This board functions as a beacon device, transmitting infrared rays at a wide angle over nine VSMB2948SL LEDs, which nearby infrared receivers, such as the one on IR Click, can detect. The IR LEDs are packed in a half-circle way allowing the transmitted infrared rays to cover a broader space in front of this Click board™. This Click board™ makes the perfect solution for high pulses current operation, such as remote controls, robots, and more.
IR Beacon Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.

Availability date:
IR Beacon Click is based on the nine VSMB2948SLs, high-speed infrared emitting diodes from Vishay Semiconductors. The VSMB2948SL is a 940nm wavelength infrared emitting diode in a GaAIAs multi-quantum well (MQW) technology with high radiant power, high radiant intensity, and high speed molded in a clear untinted package with a lens. This kind of architecture allows the IR wave to have a half-intensity angle of ±25 degrees and a range of up to half of a meter that can be increased by stacking multiple IR Beacon Clicks onto the same mikroBUS™ socket.
The IR Beacon uses either UART or PWM lines of the mikroBUS™ socket, selected over the TX SEL jumpers, with PWM chosen by default, to allow the host MCU to transmit a signal to a target receiver. The mainboard MCU drives the infrared diodes through the MOD pin, providing a carrier signal which can be adjusted to match the frequency.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the PWR SEL jumper. 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.

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 MikroElektronika compilers.
This Click board™ is supported with mikroSDK - MikroElektronika 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.
