ДВС!
Есть радиоуправляемая машина на 40,680Мгц.
На плате в машине такая маркировка: HQ2109RX
Так вот - машина не едет вперед, остальные функции работают.
Подава без передатчика напряжение прям на движок в машине с разной полярностью - крутит в обе стороны.
Где копать?
Заранее спасибо.
Скорее всего, не работает приёмник. Или кнопка “вперёд” на передатчике.
Обратитесь к мастерам, что телевизоры чинят - разберутся.
Разбирал передатчик, всё там контачит.
Только вот нечем мне проверить радиосигнал он выдает или нет 😦((
