ELEGOO Motherboard for Neptune 3 Pro/Plus/Max

The stock 32-bit board from the larger Neptune 3 machines — the ZNP Robin Nano DW V2.2. It runs silent stepper drivers, which is why these printers hum instead of scream, and the familiar Marlin firmware. People usually buy one after a blown bed heater output, a stepper that stopped being detected, or a printer that started rebooting itself halfway through a job.

Specifications

• 32-bit STM32 microcontroller running Marlin
• Silent stepper drivers with heatsinks
• Headers for X, Y, Z, two extruders and three thermistors
• Plug-in wiring throughout, no soldering

Compatibility: ELEGOO Neptune 3 Pro, Neptune 3 Plus and Neptune 3 Max. The Neptune 4 series uses a different board built around a Linux SoC running Klipper.
