The Makerbase MKS Robin Nano V3.1 is a 32-bit control board designed for 3D printers (and by extension compatible CNC/laser setups) offering high performance, multi-axis capability, and flexible connectivity in a compact footprint.
It represents a substantial upgrade over earlier versions (e.g. V2.0) primarily via a more powerful microcontroller (MCU), improved memory and I/O support, and added features like USB-disk support, dual-fan control, WiFi-module support, and multi-axis motor control making it suitable for more complex or modern 3D printing machines.
Key Features
High-performance 32-bit MCU — The 168 MHz Cortex-M4 processor with FPU ensures smooth, responsive, and accurate control of stepper motors, heaters, and sensors.
Multi-axis & Multi-extruder ready — Up to 6 axes supported; dual Z-axis configuration and dual hotend (2 heating heads + bed) option makes the board suitable for complex, multi-extruder or advanced 3D printers.
Flexible firmware support — Works with popular firmwares (Marlin 2.x, Klipper, RepRap) giving users flexibility depending on printer requirements or personal preference.
Storage flexibility — Supports printing directly from SD card (TF), USB-disk, or via virtual USB (MSC/VCP), which simplifies workflow and reduces dependency on PC connection.
WiFi / Remote Printing ready — Supports connection of external WiFi module (USART1 + SPI2), enabling cloud printing, remote access or firmware updates — nice for advanced users or networked 3D printing setups.
Dual fan control & improved PWM outputs — Two independent PWM fan outputs allow for separate cooling for hotend, part cooling, or electronics — important for print quality and board cooling.
Robust protection & reliability — Power TVS protection and anti-interference improvements on sensor and MOS circuits help with stability and reduce risk of damage from voltage spikes or electrical noise.
Wide LCD/display compatibility — Compatible with many display types (touchscreen and classic LCD), enabling flexible UI/display options depending on your 3D printer or user preference.
