Hardware Notes

Couple of words about power supply. Supply chain is Single 18650 -> LDO 3.3V. I found no reason to put DC/DC because in common they have 80%-90% of efficiency, while LDO has ~78% in worst case (3.3V / 4.2V = 0.78). Do the increased complexity and cost worth several percent of efficiency? I do not think so.
