MIKROE IR Beacon Click

Product Overview

IR Beacon Click is a mikroBUS™ add-on board with an array of nine high speed infrared emitting diodes. It functions as a beacon device, transmitting infrared rays in a wide angle, which can be detected by nearby infrared receivers (such as the one on IR Click). Each of the nine VSMB2948SL diodes have a transparent plastic package that serve as tiny lenses.

The IR wave has a half intensity angle of ±25 degrees. The diodes have high radiant power and intensity with a peak wavelengths of 940nm.

IR Beacon Click is suitable for high pulse current operation. The mainboard MCU drives the infrared diodes through the mikroBUS™ MOD pin, providing a carrier signal (which can be modified to match the frequency of the receiver). Either UART or PWM can be used to transmit a signal to a target receiver (specified by the position of the TX SEL jumper is in the middle of the board).

The range is up to half a meter. You can increase it by stacking multiple IR Beacon Clicks onto a same mikroBUS™ socket.

The board can use either a 3.3V or a 5V power supply.
