Bank-Switched SRAM Memory Cartridge
Memory expansion cartridge built around a CY62256NLL-70SNC SRAM chip. An onboard switch divides the chip's 256KB of storage into four selectable 64KB banks, letting the host read and write a specific bank depending on switch position.

Engineering approach
Robotics controllers need to juggle real-time control loops, sensor input, and actuator output without the layout introducing timing jitter or noise into the control path. On this board, that translates into a component set built around CY62256NLL-70SNC and 4x 64KB Banks, with layout and stack-up decisions driven by motor drive integrity, sensor fusion timing, and expansion headers that keep the platform flexible.
