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. IrDA2 click 2 1 3 4. Essential features 1. Introduction Turn the board upside down so that bottom side is facing you upwards. Place shorter parts of the header pins in both soldering pad locations. IrDA2 Click™ is an accessory board in mikroBUS™ form factor. It’s a compact and easy solution for adding infrared communication to your device. It features TFDU4101 infrared transceiver module as well as MCP2120 infrared encoder/decoder connected with the 7.3728 MHz external crystal. IrDA2 Click™ communicates with target board via UART interface. The board is designed to use 3.3V and 5V power supply. It has a LED diode (GREEN) that indicates the presence of power supply. Turn the board upward again. Make sure to align the headers so that they are perpendicular to the board, then solder the pins carefully. 3. Plugging the board in Once you have soldered the headers your board is ready to be placed into desired mikroBUS™ socket. Make sure to align the cut in the lower-right part of the board with the markings on the silkscreen at the mikroBUS™ socket. If all of the pins are aligned correctly, push the board all the way into the socket. The combination of the TFDU4101 and MCP2120 results in support for fast and stable infrared data communication. The TFDU4101 infrared transceiver module covers the full IrDA range of more than 1m and speed up to 115.2 kbit/s. With low power consumption, all these features make this board ideal for TV and video systems, printers, fax machines, copiers, external infrared adapters, diagnostic systems and other industrial applications. click BOARD www.mikroe.com IrDA2 click Manual ver. 1.00 0 100000 020982 6.
