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. This E-block allows the use of high-power-demanding applications such as running medium-sized motors, relays and many other applications. The board allows processors in the E-Blocks range to provide the power demand that is required for these high-power applications. The board uses two 4-channel industry-standard power chips — L293D. Each channel can be used individually, forming up to eight 600mA power output stages. Two channels can be grouped together to form a full H-Bridge configuration that allows bi-directional motor control — thus enabling a total power output per H-Bridge of 1200mA. On-board resettable fuses automatically trip when too much current is consumed. These are rated to trip at 500mA in order to protect the L293 chips. The board is E-Blocks compatible and can be used with up-stream devices to boost the available output power of the processor. E-Blocks 8 channel Power Driver Output Features - E-blocks compatible

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 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. E-Blocks Power Driver Output Module Resources
