          Power. Both battery-level and 3.3V regulated power are
          available. Note that the amount of regulated power is not
          huge; TeleMetrum contains a 150mA regulator and uses, at
          peak, about 120mA or so. For applications needing more than
          a few dozen mA, placing a separate regulator on them and
          using the battery for power is probably a good idea.
