HW-243 W5500 Ethernet Network Module Hardware TCP IP 51 STM32 Single-Chip Program 1. No need to write Ethernet underlying code to implement TCPIP protocol stack 2. Support sleep mode and wake-up on LAN, internal integrated 32K bytes on-chip buffer for Ethernet packet processing 3. Support 10100MBPS transfer rate 4. Support 8 independent ports working at the same time 5. The module supports 5V or 3. 3V power supply, which is convenient for users to use in different SCM systems 6. The communication method between the module and the microcontroller is SPI protocol, which supports speeds up to 80MHz 7. If you use the 5500 Ethernet module, you only need some simple Socket programming to realize the Ethernet application 8. Support protocols: TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE 9. We provide users with the source code of the routines based on the 51 single-chip microcomputer and ISTM32 single-chip microcomputer in the "client", "server" and "UDP" three working modes, as well as a detailed manual 10. Chip model: W5500 11. Input voltage: 3.3-5v 12. Size: about 55 x 28mm
