The (often referred to as the Emax ES08MA V2) is a legendary, high-performance, and incredibly affordable 12-gram micro analog servo. It is a staple component in the RC hobby, robotics community, and DIY maker scene. Known for its durable metal gear assembly and small footprint, this servo is often the go-to upgrade from flimsy plastic-geared servos for small airplanes, helicopters, and pan-tilt mechanisms. Emax Es08ma Ii Datasheet
The is a第二代 (2nd Generation) analog micro servo. It is an upgraded version of the popular ES08A, featuring a metal gear train for increased durability and torque transmission. It is widely used in small to medium RC models (airplanes, helicopters, cars, robots) and lightweight industrial projects.
Ensure your external power supply shares a common ground (GND) wire with your microcontroller. Jittering can also indicate an insufficient power supply dropping voltage under load.
The "II" revision typically addresses weaknesses found in the first metal-gear version, such as improved output shaft retention and tighter manufacturing tolerances on the potentiometer (feedback mechanism).
While they share the same physical size, the primary difference is the gear material: Metal Gear (Durable, slightly heavier) Emax ES08MA II Datasheet: Comprehensive Guide to the
The casing is made from durable engineering plastics designed for toughness. Applications
The is a high-performance analog servo that offers excellent value. It bridges the gap between cheap, fragile 9g servos and larger, more expensive metal-geared options. Its strong torque, impressive speed, and robust metal gears make it an ideal choice for RC planes, 1:18 scale cars, robotic arms, and STEM education.
Q: What type of motor is compatible with the EMAX ES08MA II? A: The EMAX ES08MA II is compatible with brushless DC (BLDC) motors.
