We're so excited to introduce you to the Roller485 Lite Unit! It's an integrated brushless DC motor motion control kit designed with your efficiency in mind. This nifty little kit supports both 6-16V DC power input (via the PWR485 interface) and 5V input (via the Grove interface). It can even automatically adjust power coefficients to ensure optimal performance! This nifty little kit features a built-in FOC closed-loop drive system that uses a 3504 200KV brushless motor. Even without forced cooling, this little guy can still operate with a maximum continuous phase current of 0.5A and a short-term current of 1A. The driver uses a magnetic encoder for feedback, which is great for keeping an eye on things. It supports current, speed, and position control, so you can be sure it'll work just as you need it to.
And there's more! The device also has a handy 0.66-inch OLED display on the back that shows you the device's status in real-time. And there's more! It also includes an RGB indicator light and function button for easy human-computer interaction. We've made it super easy for you to put this product together! The base has LEGO-compatible mounting holes and M3 screw holes, so you can get it set up in no time. We're happy to say that the hardware and software of the Roller485 Unit are fully open-source! This means that you can use them for motion control and parameter adjustment through RS485 or I2C buses. And there's more! It also offers SWD and SWO debugging interfaces, giving developers even more flexibility. This product is great for all sorts of things, including robotic joints, motion control, industrial automation, and visual demonstration projects.
