4Pcs SG90 9g Micro Servos for RC Robot Helicopter Airplane Controls Car Boat

These are very good quality. I have used them with a raspberry pi camera to add tilt and pan functionality.It was a little bit of work to get the camera to attach to the mount and to get it to stay in place but I’m sure there were better ways than how I did it.But functionality, it works well and wasn’t much work to get put together!

At 50Hz a pulse width of 0.5ms corresponds to (0 deg) and a pulse width of 2.5ms corresponds to (180 deg).So a 2.5% duty cycle to 12.5% duty cycle is the range.The photo depicts 1ms(0 deg) to 4ms(180 deg) as the range which is not correct.All 4 worked normally and were able to traverse 0 to 180 degrees.They are not high end servos but for the price they work fine.

If youre using a Pi Pico or Esp32 to drive these with Micropython, I've found best results using a PWM object at 100hz and duty_cycle_16 between 3000 and 16000 gives you close to the whole 180 degrees. Two of these plus an S2 mini runs great on two CR2032 button cell batteries in series.

project worthy

These servos are great for the price. i somehow actually was given 8, but I guess i'll take it. so far ther have been no problems at all, and the cables are long as well.

I needed some small servos for a robotics project... these were not expensive, yet very accurate, quiet, and had more than enough power for my needs. Great product.

Absolute garbage. First two almost caught fire just plugging them in. Third one lasted maybe 5 minutes. And when it did work, it would grind. Last one probably won't even work. Don't waste your time

Purchased to use in a deerc RC boat. The plug included didn’t match but the leads where nice and long so I was able to solder the old plug onto this servo.Works as expected and now I have a few extra when/if this one fails
