This US-020 ultrasonic module can realize 2 ~ 700cm of non-contact ranging function, has 5 V of wide voltage input range, static power consumption is less than 3mA. Their own temperature sensor will revise the ranging and has many communication modes like GPIO, just like watchdog inside, very stable and reliable.
VMusic1 модуль - простой способ подключения USB FLASH drive интерфейса и воспроизведения музыки к существущей системе
VMUSIC1 модуль построен на микросхеме VNC1L-1A фирмы FTDI и позволяет не только добавить USB FLASH drive интерфейс в существующее изделие, но и добавить возможность вопроизведения MP3 и других популярных аудио форматов с USB Flash диска (с флешки). Для управления и коммуникации с модулем необходимо только 4 сигнальных цепи, +5В и земля для питания модуля. Расширенная система комманд позволяет проигрывать выбранный файл с флеш-диск, управлять громкостью воспроизведения, балансом и т.п., а также получать информацию о статусе воспроизводимого файла. Имеется возможность выбора интерфейса управления модулем – UART или SPI. Интерфейс выбирается с помощью комбинации джамперов на плате модуля.
VMUSIC1модуль очень удобное и простое решение в случае необходимости добавления возможности воспроизведения MP3 файлов в существующую аудио систему или в автомобиль, а также в другие приборы, требующие возможности оспроизведения MP3 с флешки.
КЛЮЧЕВЫЕ ОСОБЕННОСТИ:
Модуль построен на VNC1L-1A USB хост контроллере в связке с популярным декодером VS1003 для воспроизведения музыкальных файлов
USB-A коннектор для подключения USB Flash диска (флешки)
Стандарный 3,5мм аудио разъем для подключения наушников или аудио кабеля
Линейный выход для аудио сигнала
Джамперы для возможности выбора UART или SPI интерфейса
Необходим всего один внешний источник питания +5В
Индикатор обращения к флеш диску
Расширенная система комманд VDAP
Возможность программирования или обновления прошивки с флеш диска
В качестве демонстрации возможно управление модулем через USB/UART преобразователь с помощью программы VPLAY
