Подключение двух контроллеров гироскутера к одному приемнику

Для реализации 4WD привода в самоделках с применением прошитых под радиоуправление контроллеров гироскутера существует несколько способов завязать их управление на один джойстик. Этот способ годится для аппаратуры без функции микшеров. Применив такое подключение двух контроллеров гироскутера к одному приемнику, получаем одновременное управление с одного джойстика четырьмя колёсами. При этом по прежнему используется только 2 канала приемника.

Используя платы с уже имеющейся обвязкой входов в виде конденсаторов и резисторов, подключение их на один приемник требует применить смеситель на резисторах. Проверено, что в диапазоне сопротивлений резисторов от 220 до 470 Ом смеситель работает отлично, возможно он также хорошо будет работать и с бОльшим сопротивлением резисторов. Экспериментируйте.

Обратите внимание на то, что на проводах кнопки включения есть потенциал напряжения. Если Ваши платы не абсолютно идентичны, обязательно проверьте мультиметром и объединяйте выводы соблюдая полярность.

Напряжение +5 В для питания приемника берем только с одной платы, GND обеих плат объединяем.

Также необходимо уделить внимание защите от помех. Если позволяет конструкция, минимизируйте длину сигнальных проводов между приемником и платами. В противном случае используйте экранированные провода.

Не забывайте после подключения провести калибровку!
