Introduction In the world of micro servos, few models have achieved the legendary status of the Emax ES08MA II . Whether you are building a 3D-printed robotic arm, a fixed-wing RC airplane, a hexapod walker, or a small CNC machine, the "ES08MA II" is a name that frequently appears on parts lists. But what makes this specific servo so popular? The answer lies in its datasheet. The answer lies in its datasheet
The ES08MA II occupies the "sweet spot." It is significantly more durable than the SG90 (which strips easily), but 1/4th the price of the Hitec HS-65MG. For hobbyists on a budget who need metal gears, this is the default choice. Part 6: Wiring and Control Signal (From Datasheet) The wiring standard is consistent with the datasheet’s pinout diagram:
Before integrating the ES08MA II into your next project, download the official PDF datasheet and verify the revision number (look for "V2" on the PCB inside the case) to ensure you have the latest potentiometer and gear materials.
With a speed of 0.10 seconds at 6V, this is considered a medium-fast servo. It is not a race servo (like a 0.06 sec unit), but it is perfectly adequate for flight control surfaces on a 1-meter wingspan plane or dynamic leg movement in a small robot. 2.3 Torque (Stall) | Voltage | Torque (oz-in) | Torque (kg-cm) | | :--- | :--- | :--- | | 4.8V | 21.7 oz-in | 1.6 kg-cm | | 6.0V | 25.0 oz-in | 1.8 kg-cm |
