Connect to the computer for programming or data.
A charge-only cable cannot flash firmware. Example requires a USB-A host port. If your computer has only USB-C, use an appropriate USB-C data cable instead. Reuse the device’s included cable where possible; this is not a standalone power-supply recommendation.
Setup requirement — check against your configuration. Planning quantity for one build; check the selected configuration.
