DiGiYes 2Pack MG90S Micro Servo Motor Metal Geared 9G for Helicopter Airplane Boat Smart Robot Car Controls (Control Angle 360 Degree)

Not much to say about the DiGiYes 2Pack MG90S Micro Servo with metal gears. These seem like the standard MG90S servos I've gotten from various "no name" vendors over the last few years.The good news is they're cheap and work well for various project purposes, not just R/C vehicles. Each one includes 3 servo arms. Functional and affordable, they get the job done for my needs. Not much else to add!

This is a metal-geared Tower Pro branded servo, with no internal stops - it's designed to rotate continuously at a speed proportional to the delta from neutral pulse (1500us @ 50hz). I was able to integrate these with both Arduino and Esp32 projects with ease, using a separate 5v supply since several sensors are already hanging off of the dev board's supply. In motion, these are certainly audible, but it's a gentle noise... I think the metal gearing and internal lubrication does a great job of keeping friction and noise to a minimum. I'll be using these in some hobby robotics projects for which they're already a noticeable improvement over the plastic geared predecessors! These fit right into the existing mounts, and are a good value for a pair.
