I’m new to this. Can the DigiOne Signature get its dirty power through the raspberry Pi3B+ or do I need a separate 5V for that?
From the Allo website …
It needs 2 PSUs, one for 5V/2A-3A (RPI) and a second power 5V to 6V 100mA. We do recommend the cleanest power supply possible (batteries, linear but even a good SMPS will work)
The dirty side includes the Raspberry Pi and first board (hat.)
Thanks a lot for your quick answer!
Many have the stock, and inexpensive, Allo SMPS 5V 3A wall wart powering the “dirty” RPi, but invest in a good linear supply or batteries for the “clean” HAT, which will tolerate as much as 9 volts. I used a 7.5V battery pack (for excellent sound) until I purchased their SHANTI lps to save time and aggravation recharging every week.
Would it not be nice if there was a battery pack that automatically recharged at preset times?
I almost have this set-up but “automatic” is whenever there is sun and that’s usually during the day when I’m at work and not listening: https://voltaicsystems.com/solar-panel-kits/
My DigiOne sits next to a window so solar into the Voltaic power bank and bank into the DigiOne. The Voltaic banks have an “always on” mode so the very low draw of the DigiOne doesn’t cause the pack to turn off. It’s been working very reliably up until Seattle just hit a 20 year record for darkest day ever recorded. Then the panel couldn’t keep up and I had to charge it myself.
As far as sound quality? I don’t really care. This is too convenient to change. I don’t immediately notice any change between the Voltaic and any other power bank I’ve tried. I do not own a linear supply for comparison though.
