Charge% (output) – stored charge indicator. A voltage between 0V and 3V that can be connected to a micro:bit pin. Level (output) – stored charge (raw). A voltage between 0V and 5V that can be looped directly to the enable pin, to auto-enable when charged. Note: Do not connect to micro:bit
Enable (input) – enables the power output, so that any stored energy can be used by the attached device. Power (input) – provides power to the Solar Store board, primarily so that the Charge% output works. Connect 3V and GND to micro:bit. Solar Power (input) – connect this to your Solar Panel to harvest energy, which is stored in the Solar Store. Accepts a voltage up to 10V. Make sure that + goes to the + on the Solar Panel, and - goes to the - on the Solar Panel.
Power (output) – connect your attached device here. This output is only enabled when the Enable pin is active and there is sufficient stored energy in the Solar Store. The LED (D3) will light when there is enough stored energy. Power LED – indicates that power is provided to the Solar Store and the Charge% indicator connection to the micro:bit is working.
