• Choice of a LDO to reduce power consumption

    May seem counterintuitive to use a LDO. But the DC/DC TRACO converter I used adds a no load overhead of about 15mA. I had some very low dropout regulators (LP2985) in my spare components, reducing the consumed power to 23.4mW (due to the low current drained by the MCU). There may be DC/DC dedicated to low power applications. To be investigated.
