Adafruit Energy Harvester LTC3108 Breakout - AB689 wemos Adafruit HUZZAH ESP8266 Breakout isThe LTC3108 is a highly integrated DC DC converter ideal for harvesting and managing surplus energy from extremely low input voltage sources such as TEGs (thermoelectric generators), thermopiles and small solar cells. The step up topology operates from input voltages as low as 20mV. Using a small step up transformer, the LTC3108 provides a complete power management solution for wireless sensing and data acquisition. The 2. 2V LDO powers an external
