We are following the GroveWeatherPi tutorial using a Raspberry Pi 3B to power our system using solar energy. When I plug the SunAirPlus board into the pi, the computer does not turn on. I was wondering if all the components are wired correctly. The setup currently consists of a solar panel and lipo battery plugged into the SunAirPlus. The SunAirPlus is connected to the pi through a USB PowerControl
I realize in the photos the LIPOBATIN of the PowerControl board is not connected to the JP4 pin on the SunAirPlus. I tried connecting these pins and the pi still does not turn on.
The output voltage is 3.7V, might be too low? The pi does turn on when the battery is directly plugged in.
The pi also doesn't turn on still if I plug it directly into the SunAirPlus and if I connect a 5V AC adapter to the SunAirPlus, is that normal?
Also, I was wondering what the red and green LEDs next to JP18 and JP9 on the SunAirPlus board mean and if they'd help troubleshoot the problem. The red LED lights up when the solar panel is plugged into the mini USB port.
The battery is part of a UPS powerpack that has an output voltage of 5V as well, might try connecting this by splicing together a USB port and grove connector.
