This is a downstream E-blocks peripheral module, designed to be controlled by one of the upstream E-blocks processing boards which are available in a variety of MCU/CPLD architectures.
The E-Block SD/MMC Card Reader allows investigation of Flash multimedia memory cards (up to 1GB) by implementing serial communication protocols, specifically the SPI interface. The main function of this E-block is to add the capabilities of storing and retrieving large amounts of data for use elsewhere in the system. A set of jumper links are available which allow the Card Reader E-block to be set easily for all PICmicro microcontroller SPI-compatible devices. The patch system available on board makes this board compatible with numerous other devices (any microcontroller with a USART interface).
E-Block SD/MMC Card Reader Features
- SPI serial MMC interface
- Bi-directional voltage level shifter
- Storage compatible with IBM based computers

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.
