E-blocks are small circuit boards each of which contains a block of electronics that you would typically find in an electronic or embedded system. There are more than 50 separate circuit boards in the range; from simple LED boards to more complex boards like device programmers, Bluetooth boards and TCP/IP boards.

E-blocks can be snapped together to form a wide variety of fully functioning systems. The ease and speed of construction makes E-blocks ideal for the rapid prototyping of complex electronic systems in industry, and for use by teachers and learners in colleges and universities. Use of E-blocks is well supported with complementary ranges of software, courseware and curriculum, and sensors. In addition to this the products are well supported with applications information, product datasheets, and a very active forum for support and advice.
