ELEGOO Motherboard for Neptune 4 Plus and 4 Max

The stock board from the larger Neptune 4 machines. A quad-core RK3328 runs Linux and Klipper — that's what serves the web interface and handles Input Shaper — while a dedicated STM32 microcontroller takes care of real-time motion. Splitting the work that way is how the Neptune 4 Plus and 4 Max hold high speeds without dropping steps. Ethernet, USB and a microSD slot sit on the board.
