3v Power Consumption Is Drastically Lowering Battery Life
Jan 24, 2021 · Why do we use 3.3V in circuits? Why not 3? Why not \$\pi\$ V? Why not 2.8 V, a much nicer number than 3 V? The more things like power consumption or speed matter, the less you align. Apr 15, 2022 · Reading the datasheets, I think MAX3485 is to provide 5v to the A B RS485 outputs even when 3.3V-Powered. The datasheet for the MAX485 also calls the enable inputs R̅E̅,DE as Control.
