ALAMSCN 5PCS SG90 9g Servo Motor plus 16 Channel PWM Servo Motor Driver PCA9685 IIC Module 12-Bit DIY Kit for RC Robot Arm Helicopter Airplane Car Boat Remote Control for Arduino for Raspberry pi

SG90 9g Micro Servo Specification: Red: pressure-wire Brown: Ground lead Orange:signal wire Model: SG90 Weight: 9g Stall torque: 1.8kg/cm Operating speed: 0.1sec/60degree Operating voltage: 4.8V~6V Maximum rotation angle: 180 degrees Gear medium: nylon Working mode: Simulation Temperature range: 0? ~ +55? Dead-set: 7 microseconds Size: 21.5mmX11.8mmX22.7mm Accessories: Three kinds of functional rudder angle, fixed screw, line length 25CM PCA9685 16 Channel PWM Servo Motor Driver Features: 1. With the PCA9685 as the master chip, the 16-channel 12-bit PWM Servo Driver only needs 2 pins to control 16 servos,  thus greatly reducing the occupant I/Os. 2. PCA9685 16-Channel 12-Bit PWM Servo Driver can help a lot when there are insufficient PWM output pins for the MCU in your project. 3. The only condition is that the main control chip supports I2C communication, which means enabling the communication  between the chip and PCA9685, so as to control multiple servos simultaneously. Specification: Frequency: 40-1000Hz. Channel number: 16 channel. Resolution: 12 bit. Voltage: DC 5-10V Size: 60*25mm Note:  Due to the small pulling force, it is recommended to be only suitable for ordinary small electric aircraft models,  motor fixed-wing KT boards or foam machines, and larger fixed-wing and electric helicopters are not recommended! Package includes:  5 x SG90 9g Micro Servo  1 x PWM Servo Motor Driver
