Review: Excellent Functionality and Price/Performance - Everything worked right out of the box. Only challenge is this board design and the software that runs it is a little stale, and seller doesn't help. I referenced protoneer for board documentation, Pololu video for setting driver board current, the grbl wiki for code, and transacted with the board using OpenBuilds Control.
Review: Works - Steppers all work. Drivers all work. Make sure you dial in the amperage with the screw on the driver for all of your steppers so you don't fry your driver chips; v20 on your multimeter and double the readout and that's the amps you're giving each driver. They're a bit finicky and in no way precise, and will definitely move over time. Modded some 28byj-48 to bipolar and they also run... fine... on this board... as fine as a $1 stepper will run anyway. Only complaint is that it's a bit expensive for what you're really getting. They're not TMC2209's.

## Features

- 【Nema17 Stepper Motor】Step angle: 1.8deg; Rated current: 1.7A; Holding torque: 0.45Nm (64 oz.in) ; Size: 40mm; Phase: 2; 1.8 ° ± 5% step angle (200 steps / rotation)
- 【UNO R3 Improvement Borad】 UNO is a Simple I/O platform based on open source code, and has a Processing/Wiring development environment similar to Java and C language, which is easy to understand, allowing you to quickly use UNC to make interesting things
- 【CNC Shield Board V3 Expansion Board】This expansion board can be used as a drive expansion board for engraving machines, 3D printers, etc.
- 【DRV8825 Stepper Motor Driver】Six different stepping modes: full, half, 1/4, 1/8, 1/16, 1/32; The adjustable potentiometer can adjust the maximum current output, so as to obtain a higher step rate.
- 【Mechanical Switches with 3-pin Cable】Under normal circumstances, the system needs to be equipped with at least 3 mechanical switches;easy to install, more common styles.
