Looking for a recommendation on a low‑cost robotic arm for hobby projects?

I’ve just come across a new budget robotic arm that claims to be compatible with open‑source firmware and a handful of common microcontrollers. It’s advertised as a great starter kit for people who want to dip their toes into robotics without spending a fortune.

The thing is, I’m not sure whether my Arduino Nano will be able to handle the real‑time control loop required for the arm’s servo motors, or if I should look at a more powerful board like a Raspberry Pi Zero or a Teensy 4.1. I’ve read a few forum posts that suggest the Nano can work, but the timing constraints for the arm’s motion seem tight.

I’d love to hear from anyone who’s actually built or used a similar low‑cost arm. Which microcontroller ended up giving you the best balance between cost, performance, and ease of programming? Are there any specific firmware libraries or motor drivers I should be looking for? If you’ve had trouble with the Nano, did you switch to something else, and what was the learning curve?

Also, if you know of any other budget-friendly robotic arms that come with solid community support, I’d appreciate the heads‑up. I’m hoping to get this up and running by the end of the month, so any quick wins or pitfalls to avoid would be a huge help.

Thanks in advance for the insights!
