NYSM.2 Stepper Driver Modules

The Open Source Modular Stepper Driver Standard Modules for Everyone

Every machine deserves Modularity! Licensed under GPL V3 and Released at the Ubuntu Summit 2024, NYSM2 Standard defines an open pinout standard to repurpose the M.2 Key B hardware interface to route stepper driver power and signal lines with high power capabilities of ~100W (25V@4A) total which can be further increased by higher voltage operations.

Instead of Limiting Proprietory connectors that locks you into a closed-source ecosystem, NYSM.2 Interface allows all manufacturers, Makers, Hobbyists, and Industries to utilize widely available M.2 key B interface over NYSM.2 Standard Pinout to add modularity to board and machine designs, apart from the already available advantages like Poka-Yoke designs, NYSM.2 Offers High Current capabilities, 3 reserved pins, more robust Horizontal and screw tightened mounting, and ability to utilize both top and bottom layers mounting to add double the number of drivers in the same footprint space.

We Plan to release modular versions of SmartPrintCoreH7x and SmartPrintCore Extravaganza with 2 more boards that'll adopt the new standard by Q2 2025.

This Board is a Fully Functional, production-ready variant of a TMC2209 NYSM.2 Stepper driver, for your future-ready 3D Printers.

More Info - "Not Your Standard M.2" is literally not your standard m.2 interface, and is a new open-source stepper motor driver board that utilizes the M.2 interface to control motors using the TMCxx and all other stepper drivers. Modular stepper drivers are far superior than traditional pololu footprints as it has

Poka-yoke installations: The Key's in the interfaces makes sure that you never mess up installation orientations of the driver apart from this NYSM.2 extends beyond these to provide more features as below:

physical locking mechanisms: to make sure drivers are locked in when In operation.

Horizontal installation: instead of vertical mounting, to not only save space in Z axis, but to also make the system less fragile to accidental damage if stuck by a physical shock.

Top and Bottom Installations: since NYSM.2 utilizes SMD and single layer mounted connectors, it means that it is possible to add by design 2 NYSM.2 modules in the same footprint area, drastically reducing the required footprint for more drivers - i.e - 20 drivers in 10 drivers area by installing 10 on top layer and 10 on bottom.

highly cost effective: since M.2 is a widely available standard with high MOQs already flooding the industry, the M.2 connectors can be integrated at very low costs into your design, where the stepper card doesn't even need a connector as it uses an edge connector built into the PCB only. in comparison to other modular standards that uses custom repurposed obsolete connector that has low manufacturing volumes. With NYSM.2 we can adopt a modular standard at almost same cost of a traditional pololu stepper drivers.

Powerful in terms of power: NYSM.2 utilizes 8 contacts(0.5A per pin) per power connection to deliver a whopping 4A to the motors, that too at 24V, that totals to 96W per driver. moreover it is theoretically possible to get more power out of it by increasing the voltages.

But that is not the best thing about NYSM.2 standard, the only best thing about it is only and only it's open source nature and GPL V3 license, that allows creators, hobbyist and manufacturers worldwide to move to a new and open modular stepper driver interface standard. unlike other modular stepper interfaces, this interface is open inside out, and is not designed to lock you into single specific manufacturer's ecosystem. and is made for the world to use.

Key Features for this NYSM.2 TMC2209 Board: NYSM.2 Interface: Compact, modular design that fits into M.2 slots, making it easy to install and maintain. TMC2209 Stepper Driver: One of the Industry-leading drivers for stepper motors, featuring sensorless homing, stall detection, and ultra-quiet operation. Assembly and Setup Step 1: Insert the NYSM.2 board into an M.2 slot. Step 2: Connect your stepper motor wires to the appropriate output terminals. Step 3: Configure your firmware (e.g., Marlin or Klipper) to control the TMC2209 driver. Step 4: Power on the system, and your motors are ready.
