Specifications: Adapted voltage: 3.6-16V Board size: Approx. 25x9mm Weight: 2.8g Support 500-2500us 180-degree servo Mini and lightweight, compact to use One 3P cable (10cm in length) and one plug design, simple to connect Application: Where you want to extend the angle with a remote control, such as (robot arm, homemade sailboat). Please note that some servos meet the limit plate before it reaches 180 degrees. Do not perform hard operation and cause the motor to stall. The steering gear reversal is to give the complementary signal of the steering gear, for example, it is currently 1500, and the motor sets the middle position. At this time, if the steering gear is rotated 9 degrees counterclockwise, the signal of 1600 should be given, but the reverser changes it. It is 1400 so that the steering gear rotates 9 degrees clockwise. Note: This is the extension of the remote control servo angle, which originally controlled 90 degrees, and expanded to control the 180 degree servo. It does not directly change the 90-degree steering gear to 180-degree. Servo Angle Expander 1. The servos on the market do not write how many degrees/or 90 degrees/or 180 degrees. They are generally 180-degree servos. 2. The PWM output of common RC model remote controls generally reaches a standard pulse width of 1000-2000US (so the maximum steering angle can reach 90 degrees) 3. Through the principle of expansion module: extend it to 500-2500US to achieve rotation The effect of 180 degrees. (Early stage: The servo supports a pulse width of 500-2500US and can rotate 180 degrees) 4. Application occasions: Users who need to use remote control to expand the pulse width signal requirements, such as (robot arm, homemade sailboat) (Note: Some servos will encounters the limit plate before reaching 180 degrees, do not cause the motor to stall by hard operation) Servo Slow Player 1. When we usually control the servo through the operating lever of the remote control, when the signal switches from low to high in an instant, the servo will quickly rotate from one side to the other. 2. Through the principle of the slow amplifier module: slow down the speed, that is, the servo rotation will not reach the final signal position of the operating rod instantly, but will slow down the rotation to the end point. 3. Application occasions: For users who need to slow down the speed of actual remote control operation and the speed of accessory execution. Commonly used accessories: servos, ESCs (such as: simulation effects of retracting and retracting the landing gear of model aircraft) (Note: This slow playback does not mean that after the operation, wait for a period of time before starting to execute the output, but that the time period from the beginning to the end after the operation becomes slow) Package Included: 1x Servo Angle Expander or 1x Servo Slow Player
