IW02 AA51883 那个脚是接独立舵机信号线的?

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)

请问楼主是怎么接线的啊?

舵机马达线接马达线,还有一条信号线 不知道怎么接了

5188

AA51883

我看过图纸, 都是第二脚是舵机信号.

你把原来的这脚断开, 就可以取出舵机信号了, 注意是断开引脚, 不要去割电路板.这样, 就可以从电路板原来进5188的那个地方, 引出舵机信事情, AA51883很小, 操作要万分小心,建议用热风枪把 AA51883 吹掉, 再直接焊线.

具体是哪个脚可以搜搜帖子,里面有介绍,但是按我的理解应该是舵机的信号线接那个脚,舵机电源线直接接到板子的电源线而不是转向马达的电源线。另外注意电源不是2S锂电,否则可能会烧舵机,板子可以受得了2S20C里聚合物电池(我试过的),但是舵机不一定受得了。

能详细点解下吗?

多谢,确实,AA51883太细小了...

嗯...为什么直接接电源呢?道理是什么?
