Ethernet, WIZ (DIY)

Regular price $21.00 Sale

Single-chip network SPI bus interface chip, TCP/IP protocol. Compatible with the DIY series.

Microduino-W5500 is an ethernet control module developed by the network chip W5500. Microduino-W5500 must be stacked with Microduino-RJ45 to compose into a completed network module, and it can’t be used alone.


  • A firenew all hardware TCP/IP protocol stack network chip since W5100, W5200 and W5300. With lower power consumption and operating temperature and modified process, and it’s the best solution choice of the embedded Ethernet;
  • Adopts U-shape 27pin Microduino standard interface, and can be used stacked with module Microduino-RJ45 . Plug and play. The whole size is smaller;
  • Open-source hardware circuit design, and compatible-with-Arduino compilation development environment;
  • With unified Microduino interface specification and abundant periphery modules, which make it can be extended and connected with other modules and sensors which meet the Microduino interface specification, quickly, conveniently and flexibly;
  • With 2.54-spacing female header connector interface, which is convenient for the integration to the pegboard.


  • Communication protocol
    • Supports hardware TCP/IP protocol:TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE
    • Supports 8 separate ports(Socket)to communicate at the same time.
    • With built-in 10BaseT/100BaseTX Ethernet Phy.
    • Supports automatic negotiation(10/100-Based full duplex/half duplex).
  • Operating characteristic
    • Supports power down mode.
    • Supports wake-on-lan.
    • Supports automatic reply(full duplex/half duplex)
  • Update rate
    • Supports high speed serial peripheral interfaces.
    • With 32k bytes interior send and receive buffer.
  • Interface features
    • TTL level input
    • Single power supply: 3.3V;
    • Doesn’t support IP burst.

Status indicator

    • Two programmable LED outputs used to show the status of connection, sending, receiving, conflict, full duplex and half duplex;
  • Pin introduction:

SO D11 Data output of SPI interface
SI D12 Input of SPI interface
SCK D13 Clock input of SPI interface
CS Default is D10, which can be changed into D8 Chip select input of SPI interface.
RESET RESET Low level effective device reset input
