2. Soldering the headers Before using your click board, make sure to solder 1x8 male headers to both left and right side of the board. Two 1x8 male headers are included with the board in the package. 1 IR click 2 3 1. Introduction 4. Essential features IR Click with its TSOP38338 and QEE113 ICs is an easy and compact solution for infrared remote control communication protocol. The TSOP38338 - 38 kHz (carrier frequency) receiver is recommended for RCMM, NEC, RC5, Turn the board upside down so that Turn the board upward again. Make sure RC6, r-step and XMP codes. It is not sensitive to bottom side is facing you upwards. Place to align the headers so that they are supply voltage ripple and noisy environments. shorter parts of the header pins in both perpendicular to the board, then solder the It has improved immunity against ambient soldering pad locations. pins carefully. light and shielding against EMI. IR Click is an add-on board in mikroBUS form factor. Its a compact and easy 3. Plugging the board in solution for adding infrared (IR) module click to your design. It features TSOP38338 Once you have soldered the headers your IR receiver module as well as QEE113 IR board is ready to be placed into desired BOARD emitting diode. IR Click communicates mikroBUS socket. Make sure to align the www.mikroe.com with the target board microcontroller via cut in the lower-right part of the board mikroBUS UART (Tx, Rx), AN, and PWM with the markings on the silkscreen at the IR click Manual lines. The board is designed to use 3.3V mikroBUS socket. If all of the pins are ver. 1.01 and 5V power supply. LED diode (GREEN) aligned correctly, push the board all indicates the presence of power supply. the way into the socket. 0 100000 0231816. SMD Jumpers 5. IR Click Board Schematic Target board microcontroller can transmit signal to IR emitting diode via PWM (IN) or RX as well as receive signal from IR receiver via AN (OUT) or TX mikroBUS pins. Jumpers J2 and J3 enable you to choose between these VCC IN two ways. J1 zero-ohm SMD jumper is used to LED INPUT SEL RX select between 3.3V or 5V power supply. J1 VCC R1 PWR SEL 100 jumper is soldered in 3.3V position by default. J2 OUT J1 LD2 RCV OUTPUT SEL QEE113 TX J3 7.
