Simon,
As MoOde is so wonderfully efficient the CPU load is generally low even when indexing and with CPU set to Performance rather than On Demand.
Mostly of my output is via USB to other USB-i2c-Hats or devices.
Hence I am a little parsimonious with power supplies and run my Pi1/2/and Zeros from the little 2-Amp apple chargers I buy used in bulk at $3 each.
My Pi3s I run on Official Pi2 supplies and my Pi4 usually runs on an official Pi3 supply.
When running HATs I either supply them separately or use the Salas L-Adapter to run both the Pi and it's HAT.
As I was quickly experimenting with the Pi4 and ProtoDac attached I forgot to change out the power supply and the combo wouldn't boot on the Pi3 supply..of course.
I swapped it out for the super-grunty L-adapter.
As I don't have an official Pi4 supply I can't test it with the combo sorry.
Quote:Bob - to be clear, you're saying you have the ProtoDac powered by the Pi 4 via the GPIO connector, but using a single Salas L-adapter?Yes.
