futaba接收机的电压回传
平常玩油车,知道futaba接收机自带电压回传功能,不过回传的是接收机的工作电源电压,最近又玩电车了,就希望能回传电池的电压数据,最简单快捷方式是买一个futaba原厂的外置电压模块,170块钱,舍不得,也增加布线,不好看,只能另辟思路了。偶然蹲厕所的时候想起来,能不能把接收机内带的电压检测外引出来接去动力电池那里呢?这样电压检测就是动力电池的了,马上行动

逆向思维分析一下电路,有个初步方向了,找出内部电压检测,切断,再引一根检测线出来

断开内部电压检测后,开机,发射机显示接收机电压3.5v.这个电压知道顺丰哪里的电压了,不管它

把检测线接去动力电池的正极,发射机显示接收机电压马上变成7.9v了,实际电池电压是7.69,有偏差,得串个二极管,接收机内部原厂设计就是有串了一个二极管的
到此为止,实验是成功了,后面再研究一下如何布线,例如,把检测电压信号从电调那里跟信号线一起引过来,这样就不用再单独引一根线去动力电池那里了。
上面有过错误语句,知道顺丰哪里电压,应该是不知道哪里电压 补充个改装位置,大家可以参考一下,先确定自己动手能力能否胜任再折腾,弄坏了接收机别骂我

不知道这个最高能测到多少电压hh 但是这个最高就支持8.4 不错不错 你好请问一下这个接收机无法对频问题,通电后红绿灯交替闪烁,无法对频,这应该怎么解决? 200多块的接收机这么搞会不会太破费了https://app.rcfans.com/public/emotion/face_wulian.pnghttps://app.rcfans.com/public/emotion/face_wulian.pnghttps://app.rcfans.com/public/emotion/face_wulian.png
