A4988 Stepper Motor Driver:
A4988 Stepper Motor Driver Board is a breakout board for Allegro’s A4988 DMOS Micro stepping Driver with Translator and Overcurrent Protection;

Low RDS (On) Output :
Automatic current decay mode detection / selection
Mix with slow current decay modes
Synchronous rectification for low power dissipation
Internal UVLO
Crossover-current protection
3.3 and 5 V compatible logic supply
Thermal shutdown circuitry
Ground fault protection
Load short-circuit protection
Five selectable step modes: full, 1/2, 1/4, 1/8 and 1/16
Warning: Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver. (More generally, rewiring anything while it is powered is asking for trouble).

    My first Arduino UNO experience. I received my Robotlinking Arduino UNO R3 today via USPS mail. It was packaged in a yellow padded envelope. I was a little worried when I got it as the post office is not known for being gentle. Luckily it came in one piece. When I opened the envelope The UNO was in a small box not much bigger than itself and the cable was with it both inside an anti static bag. This is my first experience with Arduino so I have been excited about getting it. The first thing I did was plug it in and load and…

    Bought two – both arrived on time, and work as expected. Bought two of these, and they both seem to work great. Plugged them into PC, opened the software, and uploaded a test sketch immediately. While these are branded RobotCube, and the boards are as pictured, they came in boxes with RobotLinking brand, which is fine with me, as I previously purchased one under RobotLinking brand (found here, though currently unavailable) which also worked well. My only complaint might be that sometimes the pin headers aren’t 100% perfectly aligned; though this…
