E-Blocks Slide Switch Board, 8 Switches US$39.60

E-Blocks Slide Switch Board, 8 Switches

This is a downstream E-blocks peripheral module, designed to be connected to one of the upstream E-blocks processing boards which are available in a variety of MCU/CPLD architectures.

This module allows you to connect up to eight switches to any of the I/O ports on an upstream E-Blocks control board. Further downstream E-blocks peripheral modules can be connected to this E-Block via the downstream 9-pin Sub-D connector. The two D-type connectors provide a bus system that enables clean access to all I/O lines. A +5V or +3.3V connection is required to enable the switching from logic level 0 (0V) to logic level 1 (+5V / +3.3V). This is achieved easily by connecting a wire using the screw terminal blocks provided on most E-Block boards.

E-Blocks Slide Switch Board Features

  • Compatible with most I/O ports in the E-Block range (up to 8 I/O lines via 9-way D-type connector)
  • Upstream and downstream D-type connectors
  • 3.3V compatible

The circuit board consists of eight digital inputs on a downstream 9-way D-type plug. This routes each bit of the bus to an identical switch circuit and to a 9-way D-type socket that can be used for adding further E-Blocks in a bus configuration. This switch circuit board assumes that, to operate correctly, each input on the upstream processor board will be configured as a high-impedance input. With this in mind, each circuit consists of a 4k7 pull-down resistor which, when the switch is open-circuit, ensures a logic level 0 at the output from the switch board and into the processor input pin. When a switch is closed, the output from the switch board is effectively connected via a 390Ω resistor to the positive rail (usually 5V), or to logic 1. The effect of the 4k7 pull-down resistor at that time can be deemed to be negligible.

Care must be taken when connecting another E-Block to the switch board. Make sure that the impedance placed on each line of the bus is such that the fundamental operation of the switch circuit is not impeded.

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 CPLDs, Arduino or Raspberry Pi control the whole E-Blocks system. Processing E-Blocks provide up to five 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.
