This Ethernet Overlay Shield brings us one step closer to connecting to the Particle Cloud over Ethernet. This Beta release consists of working hardware capable of negotiating a IP address with a DHCP server and sending/receiving data over TCP or UDP sockets.
The senseBox is a do-it-yourself kit for stationary and mobile sensors. With the SenseBox citizens and schools are able to measure environmental data on climate, air quality, traffic, noise, and more position-related and thus contribute to more accurate statements about local environmental phenomena. The is provided data to the Internet as Open Data and visualized map.

RS485, RS232 Interface Comfortable with W5100, W5200, W5500 Module Support STM32 program
The W5500 Ethernet module can be used to provide your projects with internet connectivity. W5500 enables users to have the Internet connectivity in their applications just by using the single chip in which TCP/IP stack, 10 / 100 Ethernet MAC and PHY embedded. Supports 8 independent sockets simultaneously. The W5500 Ethernet module has a standard RJ-45 connection. Support 3.3V and 5V input voltage and logic level from SPI. Work with All AVR(Arduino) STM, ARM boards.
This W5500 is a Ethernet module that basic on the new type chip W5500, The W5500 chip is a Hardwired TCP/IP embedded Ethernet controller that enables easier internet connection for embedded systems using SPI (Serial Peripheral Interface). W5500 suits users in need of stable internet connectivity best, using a single chip to implement TCP/IP Stack, 10/100 Ethernet MAC and PHY. Hardwired TCP/IP stack supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE, …, which has been proven through various applications over many years. W5500 uses a 32Kbytes internal buffer as its data communication memory. By using W5500, users can implement the Ethernet application they need by using a simple socket program instead of handling a complex Ethernet Controller. It is possible to use 8 independent hardware sockets simultaneously. SPI (Serial Peripheral Interface) is provided for easy integration with the external MCU. The W5500 SPI supports 80 MHz speed and the new efficient SPI protocol, so users can implement high speed network communication. In order to reduce power consumption of the system, W5500 provides WOL (Wake on LAN) and a power down mode.
