I am using the Pololu 5V Step-Up Voltage Regulator U1V11F5 to step up the 3.3v pin to 5v to run a plantower 5003 air sensor. I wired the step up booster Vin - 3.3v , gnd- gnd, shutdown - d7, vout to air sensor. It reads 5v just fine and shuts down with the D7 pin as it should. The problem is that…

The Photon can only supply 100 mA on the 3V3 pin. The Electron can supply 800 mA on the 3V3 pin. If 800 mA is not enough, then you’ll need to go with Li+.

This should bring you up to speed with solar charging.
