    Very efficient low-cost solution for short-range communications, i.e. a tiny robot toy or domotic control. Battery consume is pretty low, practically indifferent. I am very satisfied with the product, thumbs up!

    Lo compre para comunicar el módulo DHT de frsky con la app y visualizar telemetría en el movil. Todavia no lo he probado, estoy a la espera de otras piezas.

    I bought one a month ago, today I received two more. Works well and you can update the firmware very easily.

    The connection Bluetooth with an Arduino never was so easy.

    I had bought one of these a couple years ago and could not find them until I found "" , What is so special about these modules is that the data (Rx and Tx) work with 5 volts, so no need for voltage dividers,just hook them straight up to arduino,picaxe,basic stamp or whatever 5 volt system you have. shipping was a little slow but it was free and the price of the modules was nice.worth the wait.

    This wireless bluetooth serial module is absolutely amazing for beginners with arduino! I made an application myself and used this bluetooth module to control the led coloring, which is just epic! Endless possibilites. It is also easy to change the name of the module (and all the other things if you are interested).

    Great Serial Module HC-05 Wireless BluetoothIl works perfectly. I am satisfied, great product and great seller. only the shipping is a bit long about 26 days for Italy, but given the price quality, that's okay
