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 4. Essential features ETH WIZ click 2 3 The W5500 module onboard ETH Wiz click employs a variety of solutions to reduce the target MCUs memory load and enable a stable and secure Internet connection. High speed network communications are realized through a 80 MHz SPI interface. The module has 32KB of internal memory for TX/RX buffers. Reduced power consumption is achieved with Wake on LAN and power down modes. Turn the board upside down so that Turn the board upward again. Make sure Automatic handshaking, retransmit on the bottom side is facing you upwards. to align the headers so that they are collision and automatic rejection of erroneous Place shorter pins of the header into the perpendicular to the board, then solder the packets are also supported. The board is ideal appropriate soldering pads. pins carefully. for Home network devices and all sorts of embedded servers. 1. Introduction ETH Wiz click carries W5500, a 48-pin, 3. Plugging the board in 10/100 BASE-TX standalone Ethernet click controller with a hardwired TCP/IP Internet Once you have soldered the headers your protocol offload engine, along with a board is ready to be placed into the desired BOARD standard RJ-45 connector. Wiznets W5500 mikroBUS socket. Make sure to align the www.mikroe.com module supports TCP, UDP, IPv4, ICMP, ARP, cut in the lower-right part of the board with IGMP, and PPPoE protocols. ETH Wiz click the markings on the silkscreen at the communicates with the target board MCU mikroBUS socket. If all the ETH WIZ click manual ver 1.01 through mikroBUS RSTn, SCSn, SCLK, MISO, pins are aligned correctly, MOSI and INTn lines.
