Puis-je connecter à AudioPhonics Dac et connecter simultanément le powersuply commutée qui vient avec le Raspberry Pi Raspberry Pi?
English: I have built a linear powersupply for my Audiophonics dac. It can only deliver 1 ampere (A). The Raspberry pie want to have 2,2 ampere.
Can i use the linear supply to drive the Audiophonics dac and at the same time use the switched supply that came with the raspberry pie to drive the raspberry pie?
Are you talking about a U-Sabre or I-Sabre ?
if you're talking about an I2S DAC, there's no need to power up the Pi separatly.
The PI will be powered trough GPIO pins.
If you have a PI 2 or 3 1A will not be enough.
Powering the pi itself with a standard SMPS wall adapter will pollute the clean DAC.
And thanks for your answer. This is My dac. http://www.audiophonics.fr/fr/dac-diy/a ... tml#idTab4" onclick="window.open(this.href);return false;
This is the pie. https://thepihut.com/products/raspberry-pi-3-model-b" onclick="window.open(this.href);return false;
Are there any modifications (bend some pins) that i can do to separate the pie and the dac from eachother, so that i can power them separately?
