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 for RF communications at carrier frequencies of 915 MHz. The board can be switched between transmit and receive mode at baud rates up to and including 115 Kbps. The ALPHA-TRX915S RF module itself features programmable receiver bandwidth, sensitivity and a range of up to 300 meters. This board uses SPI to communicate with an E-Block processor board. The 915 MHz frequency band is for use in ITU Region 2 (i.e. the Americas) only. This device is illegal to use in Europe and Japan. Other areas, check your local regulations. E-Blocks ISM-band RF Board Resources 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.
