搞了半天搞不懂怎么把9克舵机信号线接上去,IW02新板,没得原来的yt5188,取代的是AA51883。我在网上找了图纸,讲第八脚是信号输入脚(Vin),试了下还是不行,抖舵,加往一边转,(我用的是恒龙控)。鄙人不会电子哈...哪位大哥指点下,多谢多谢~ PIN NO. PIN NAME PIN FUNCTION 1 EXP1 Connect to the (Q1) base of the external PNP transistor 2 CFP Fixed driving pulse setting 3 VCC Power supply pin 5 VREG Constant output voltage of 2.5V (typical). Make connections from this pin to a potentiometer or pulse stretcher resistor. 6 CST Connect the capacitor and resistor of the pulse stretcher section. 7 CDB Dead band setting by connecting a capacitor. 8 VIN Input signal, an adjustable pulse of 20ms cycle and 1.0-2.0ms pulse-width, operate with a positive pulse of peak value 3V or greater. 9 RT Timing Resistor, connect a resistor that will determine the value of the constant current of this pin. A resistor of 18kΩ will yield a current of 1.0mA. 10 CT Local pulse setting, connect a capacitor that will generate a triangular wave by constant current charging. 11 POT Servo position voltage from the potentiometer connected to the servo's drive shaft. 12 EXP2 Connect to the (Q2) base of the external PNP transistor 13 OUT2 Output Driver 2 (connect to motor) 15 GND Ground pin 16 OUT1 Output Driver 1 (connect to motor) |
