Based on the W3100A hardwired TCP/IP stack chip from WizNET, this E-blocks board adds Ethernet functionality to an existing microprocessor based system without the necessity of a developing the TCP/IP software stack. As well as the Ethernet protocol, the module supports 10/100 connection and a number of protocols including UDP, IP, ARP, ICMP, DCHP, ARP, DLC and MAC. The unit interfaces to a microprocessor using I2C serial communication. The patch jumpers on the board allow more than one Ethernet module to be connected to the I2C bus.

E-blocks Overview

E-blocks can be put together to form a variety of systems that can be used for teaching and learning electronics, and for the rapid prototyping of complex electronic systems.

Each E-block has one or more 9-way D-type connectors that provide up to 8 input/output lines and a ground line. These D-type connectors allow connection between E-blocks to be made in buses of multiples of 8 lines, just like a real electronic system. Power is routed separately to those E-blocks that need it.

Processing E-blocks control the whole E-blocks system. PICmicro microcontrollers are used as the preferred processor; they provide up to 5 E-block ports with up to 8 lines per port.
