This manual introduces the E-blocks internet board EB023 product information, including product introduction, appearance, circuit diagram, etc.
The EB023-00-1 Internet Board from Matrix Multimedia adds Ethernet and TCP/IP capabilities to microprocessor or FPGA projects. It includes a TCP/IP stack, a physical‑layer chip and an RJ45 connector, and communicates with a microcontroller via a PCO interface.
The board supports 10/100 Base‑TX operation, half/full duplex, auto‑negotiation and IEEE 802.3/802.3u compliance. It works with 3.3 V or 5 V systems, provides network status LEDs, and can handle up to four simultaneous connections. Detailed board layout, jumper settings, testing procedures and troubleshooting steps are included.
