Constructing a Raspberry Pi RP2040 Low-Power Sensor Node – Day 3

The title of today’s lecture says it all. We are going to select components to power our RP2040 sensor node. The idea is to keep our sensor node’s battery alive as long as possible while delivering data to the host at specified intervals. To avoid excessive servicing of the sensor node’s battery, we will resort to every dirty little power-saving trick we can come up with.
