Overview
The IR Beacon Click Board™ 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 Board™). Each of the nine VSMB2948SL diodes has a transparent plastic package that serves 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.
The IR Beacon Click Board™ 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 Click Board™s onto a same mikroBUS socket.
The board can use either a 3.3V or a 5V power supply.
