Project using Pico W and some sensors to send measurements to LAN via WiFi. To be solar powered during the day and LiFePO4 at night. All your project pages are for 3.7 volt LiPo, not 3.2 volt LiFePO4. Is there a solar charger circuit for LiFePO4? LiFePO4 to Pico?
At 3.2 volts, I guess I would need two cells changed from 12 volts. I need about six of the finished project. A single cell with boost would be cheaper.
The Pico can run at a wide range of voltages but at least one sensor needs a stable input voltage to give meaningful results to the ADC input. Can the Pico 3.3 volt output work with an input voltage jumping between 3.2 and 3.7 volts?
