Does everything I need to automate a Lego project. I'm using a pair of limit switches to keep some continuous-rotation servos within the bounds I need.

Now, if only M5Stack had a 4-input ADS.

A good module for making small mobile robots.

This device is EXACTLY what I need for prototyping, it's like they designed it just for me and my thesis. There are only things stopping me from giving it five stars. First, there is no indication for when the battery is charged or when it's low, so it often just shuts down when I'm in the middle of working with it. I've often left it plugged in for hours overnight and it still didn't have enough charge to even turn on by morning. I highly recommend getting an external charger for the battery, it's been a lifesaver for me. The second thing is that even though there is support for developing in the Arduino environment, there is little to no documentation about how to do so - you simply have to dig through the source code to figure it out. Nonetheless, I'm super excited about this device!

Batteries, microcontrollers, motor drivers for DC motors...etc, You get all the elements you need to create robots and other mechatronics in this product.

If you are a MAKER, you should have one.

for years I've been looking for a all in one robot controller. This is as close as I've found. A few things that I would add would be more GPIO (or a way to read wheel encoders. (See Pololu Romi Chassis as an example)), a distance sensor ( Time of flight ranging, or ultra sonic). Also needs an led to indicate that the battery is charging. Otherwise, I really enjoy the size, and functionality of the Atom Motion.
