Good value but needs a heatsink
The board functions well and is easy to wire. However, I recommend adding a small heatsink if you plan to run currents above 1.5A for extended periods.

Exactly as described
No issues with compatibility. It paired instantly with my Arduino controller. The documentation provided by the seller was also helpful.

Perfect for my CNC upgrade
This driver works flawlessly with my NEMA 17 motors. The microstepping is smooth and the heat dissipation is adequate for continuous operation at moderate speeds.

Best budget driver
I have replaced three other brands with this Shanshe model. It runs quieter and cooler than my previous drivers. Highly recommended.

Solid performance
Works great for 3D printer extruders. Only giving 4 stars because the terminal screws are a bit small, but otherwise excellent quality.

Reliable and compact
Used this in a custom camera slider project. The form factor is great for tight spaces, and the signal response is very precise.
Q: Does this come with a heatsink pre-installed?
A: No, the module does not come with a pre-installed heatsink, but it has mounting holes compatible with standard small aluminum heatsinks which are recommended for high-load applications.
Q: Does this support 5V logic signals from a Raspberry Pi?
A: Yes, the MD-2322 is compatible with 3.3V and 5V logic levels, making it safe to use directly with Raspberry Pi GPIO pins.
Q: What is the maximum voltage I can supply without damaging the board?
A: The maximum recommended input voltage is 24V DC. Exceeding this limit may damage the internal components.
Q: Can I daisy chain multiple of these drivers?
A: You cannot daisy chain the power or motor outputs, but you can connect the STEP and DIR signal lines from one controller to multiple drivers simultaneously.
Q: Is there a potentiometer to adjust the current manually?
A: Yes, there is a small trimmer potentiometer on the board labeled 'I-REF' that allows you to manually adjust the motor current output.
