Hello all, i think this question could also be answered by people who use the older CSR6xxxx chips as well, i like to use the QCC3003 bt amplifiers as for their size and ability to quickly hook up to a USB/SPI and modify the EQ settings they make great lowfi portable options.
My last project i used the same amp, 3d printed my version of an 80's ghettoblaster and had a great time using it with a nice combo of DMA45's and ND90-PR's. One thing that let me down as that i used about 4-5 3v LED Diodes and significantly slashed the run time of the singular 18650 battery.
As i need to fix up the voltage step up module as i think it failed, it made me think if i could save some of the battery life by attempting to solder 2 LED bulbs directly onto the chip itself, so then they actually have some purpose when the button is activated. Watching a video using the CSR6xxxx chip variant, it looks like a guys managed to do this as it uses 5v (apparently), so was hoping that as it was already pulling down some mA's that i could save by utilising the same. Has anyone done this with any of the variants and is it possible?
I would still like to know if anyone has managed to upload an audio/wav/mp3 to these chips to use as the intiation/bootup sounds, as i beleive it can be done, but might be a little tricky.
