The Arduino MEGA-2560 is a versatile microcontroller board, but it has only 8 KB SRAM. SCIDYNE recently developed the XMEM+ to enhance a standard MEGA in two ways. It increases SRAM up to 512 KB and provides True Parallel Bus Expansion. The XMEM+ plugs on top using the standard Arduino R3 stack-through connector pattern. This enables you to build systems around multiple Arduino shields. Once enabled in software, the XMEM+ becomes an integral part of the accessible MEGA memory.
The XMEM+ also provides a fixed 23K Expansion Bus for connecting custom parallel type circuitry. Buffered Read, Write, Enable, Reset, 8-bit Data, and 16-bit Address signals are fully accessible for off-board prototyping. The XMEM+ makes any Arduino MEGA system much better suited for memory-intensive applications involving extended data logging, deep memory buffers, large arrays, and complex data structures. Target applications include industrial control systems, signage, robotics, IoT, product development, and education.
The introductory price is $39.99.
