LewanSoul (Lx-15d Without Bracket) - LX-15D High Torque Durable Full Metal Gear Serial Bus Servo with Real-Time Feedback of Position Voltage Temperature, RGB Colour Indicator, Metal Horn for Robot

This is a serial bus servo, so it doesn't work with a PWM signal like a lot of other servos. There is an adapter board available to control the servo with a computer via USB. It's quite strong and appears to be well made.

Le moteur n'a pas de PID(asservissement), les moteurs communiquent entre eux en TTL(pas le choix RS-485), les moteurs HiWonder sont de faible puissance, mais ils sont un peu plus précis que les moteurs PWM. Si vous acheter le controleur Hiwonder, vous pouvez gérer le temps des déplacements, ce qui améliore de beaucoup la fluidité lorsqu'il y a plusieurs mouvements d'un robot. Si vous désirez une coche plus haute pour des moteurs avec PID et beaucoup d'autres options, alors il faut regarder les moteurs de dynamixel (robotis.us) et le(s) contrôleur(s) Robot Operating System vendu par robotis aussi comme OpenCR, mais là c'est deux coches plus complexe.

This is smaller than an XL430 but with a theoretical stall torque that's equivalent at 6v to that of an 11.1v XL430, at less than half the price! I'm still in the process of getting it set up, so will update if it doesn't meet its spec sheet, but that's pretty impressive. Another advantage over Dynamixel's servos is that these seem pretty easy to set up using a ready made arduino library. YOU DO NOT NEED THE SUGGESTED SERIAL CONTROL BOARD. This primarily finds use when connecting directly to a computer. The XL430 does give more info on readout, but all the necessary info is there on these LX-15Ds.There were no instructions included, and Amazon doesn't like external links in reviews so if you're looking for documentation, there's ton on the manufacturer's site.Hiwonder's website > Downloads > Servo and Servo Controller > Hiwonder Serial Bus Servo > "download all" takes you to a public Google Drive folder with tons of resources for all their servos, including a quick start guide for sbus using arduinos.

This was my first attempt at a serial controlled servo and had a LOT of trouble getting it to just work. I ended up needing a dedicated control board just to use it with an MCU. But it is VERY torquey, and well protected. The mounting system works well.
