About the NYSM2 Open Stepper Standard PCB

NYSM2 Open Stepper Standard is an open source PCB design by BoltzRnD, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 22 × 28.5 mm, with 17 components from 11 distinct parts.

Other key parts include the TMC2209 and M.2-B-KEY. By type, the board carries 7 capacitors, 7 resistors and 2 ICs.

It belongs with the robotics & motion designs in this gallery.

From the project

An M.2 Key B Based Open Modular Stasndard for 3D Printer Stepper Driver Modules.

Modular stepper drivers are far superior than traditional pololu footprints as it has

1. 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:

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