|---|---|---|

| Battery | JST PH 2-pin port or terminal block | JST PH 2-pin port |
| USB | micro-USB | USB-C |
| regulated 5V power to load | USB-A and/or switchable header pins | terminal block |
| Solar panel | terminal block | solder to VIN header pad |
| monitor battery voltage | undocumented header pin | solder to VBat header pad |
