    Qualcomm CSR8645 с bluetooth. Установка модуля в автомагнитолу Alpine CDA-9883R [aptX работает, проверено].

    Bluetooth-модуль Qualcomm CSR8645 с питанием от 12В, с подтверждённой поддержкой Qualcomm aptX, Bluetooth 4.1, малым потреблением (не более 0.05А) и установкой в автомагнитолу.


    У меня в машине установлена магнитола Alpine CDA-9883R, в которой есть только радио, да CD привод. Захотелось простого: слушать музыку с телефона/планшета.
    Выбор был между: 1) fm-модулем в прикуриватель 2) проводом AUX 3) заменой магнитолы.

    Первый вариант был убран из-за низкого качества передаваемого звука. Второй из-за неудобства возни с проводом. После медленного подползания к третьему варианту наткнулся в обзорах на bluetooth-модули, которые можно встраивать в домашние колонки.

    Выбор пал на чип CSR8645, ну а на aliexpress выбрал продавца по наибольшему количеству заказов. Брал версию с питанием от 12В.

    Прямого входа AUX в CDA-9883R нет (только через переходник), поэтому разрезал кабель, выкинул лишнее и запаялся на провода левого и правого каналов. Чтобы включить вход на этот канал, нужно в настройках включить AUX+, но на drive2.ru один человек напаял провода прямо на плату и, по его фотографиям, он воспроизводит звук через простой AUX. Думаю по аналогии с этой магнитолой, так же можно поступить и с любой другой.


    Из-за нехватки места под bluetooth-модуль, а так же из-за редкого использования выкинул cd-привод. В освободившемся пространстве расположил модуль так, что его светодиод, сигнализирующий о работе модуля, виден через прорезь проёма под CD диски. Рядом просверлены отверстия для кнопок управления модулем: сопряжение, увеличение уровня громкости, уменьшение уровня громкости (сразу не сообразил наклеить малярный скотч и провести линию, чтобы ровно сделать отверстия, а потом уже не стал переделывать, всё равно не видно).

    Сами кнопки закреплены на пластиковой боковине с помощью эпоксидной смолы. Питание модуля выведено на управляющий провод магнитолы (тот, который на замок зажигания).




    Дальность приёма модуля в открытом состоянии соответствует заявленным характеристикам, в другой комнате через закрытые двери приём отличный, без потерь сигнала. Были опасения, что закрытый металлический корпус магнитолы существенно ограничит дальность передатчика, но опасения не подтвердились — в установленной магнитоле и закрытой машине дальность приёма до 10 метров от машины.

    В качестве вывода: качество воспроизведения через модуль не ухудшается, посторонних призвуков и шумов не наблюдается, тишина воспроизводится в колонках с еле различимым шумом, сравнимым с трактом от бывшего cd, удобство использования магнитолы повысилось (fm режим больше не использую).

    Модулем очень доволен, рекомендую к покупке.
