PERFEITO ESTADO
Arrived nice and quick, packaged well. Haven't had time to wire one up yet but I'm confident in the quality.
According to the announcement
Product according to the description of the notice
good product
Sortie puissante, mais attention il y a un rejet assez important de parasites sur l'alimentation, ce qui peut crée un grésillement sur un module BT alimenté en parallèle (dans ce cas puisque l'ampli est assez puissant, il suffi de rajouter un résistant (44k ohm dans mon cas) pour reduire de façon significative ce grésillement)
Works really well on my yaesu 857d ham radio..... I use it in my car and the audio output of the radio is to low to hear so I used this simple little op amp to boost my external speaker and now it's very loud...... excellent simple fix for a problem that was driving me crazy... thanks banggood
ok
You arrived well
Not yet tested but they look good. components are okay and well soldered on the board. I will add more info when I will use them. Fast shipping.
