If you want to experiment with or teach about various kinds of sensors using an E-blocks environment, you can get this kit that includes 16 sensor modules and the E-Blocks Sensors Motherboard, all in a neat organizer case that will protect the pins of the sensor modules that aren't in use.
If the case is not important to you, it actually is cheaper to buy all the boards individually.
E-Blocks Sensors Bundle Contents
This bundle does not include a microcontroller board. The Sensors Motherboard is a downstream E-block; it must be connected to one of the upstream E-blocks processing boards.
E-Blocks Overview E-blocks are small circuit boards each of which contains a block of electronics that you would typically find in an electronic system. Each E-block performs a separate function as either an input sub-system, an output sub-system, an input/output sub-system or a processing sub-system.
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 eight 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 based on PIC, dsPIC, ARM or AVR microcontrollers, Altera FPGAs, Arduino or Raspberry Pi control the whole E-blocks system. These "upstream" E-blocks provide up to eight input/output ports with up to eight lines per port.
Please see the E-blocks Category for a list of available components. For more details on E-blocks, see the E-blocks User Guide (in English, French, German and Spanish) or watch the Introduction to E-blocks video.
