Hey, thanks for the tip and all the info.
I went to the datasheet and the power consumption of the ethernet chip WIZnet W5500 in POWER DOWN MODE (sleeping) doesn't look good for low power devices: 13 mA .
For low power setups with Muons, I believe the best approach would be to deactivate the 3v3_AUX, which unfortunately means we won't be able to use the QWIIC connector. Additionally, the 3v3 on the 40-pin expansion can't be used either.
Thanks
