BOOM BOX 2 - custom made Bluetooth Speaker - NEW verson
EN
Somewhere in the list of topics in my website, I already show one self made battery driven Bluetooth Speaker with proper size.
Well, now is the time to to extend that a bit, and the new build use already two batteries, bigger amplifier and bigger speakers.
The amplifier, once again Chinese and use Bluetooth / 3.5mm jack as input source. The difference with previous one is the missing of SD card / USB reader.
The amplifier itself is based on TDA7498E chip and on paper it will be able to output about 150W@4ohm with 36V of power supply. The bridged mode will be of about 200W.. That is quite a lot for such a small foot print chip but let`s see.
