我有一块thinkpad 1350 开发板，我不想用USB口供电，想用外接电源供电如何进行连接，供电标准是5v还是 .3.3v。谢谢。
Usually, power is supplied from USB and a jumper is mounted in the position marked XDS110 power (factory default). If you want to power CC1310 from an external supply, move the jumper to the position marked Extern. Pwr, and connect the external supply to the 3V3 pin on J1. Also make sure to remove the 3V3 jumper from the main jumper block. Make sure that the voltage applied stays within the supply range of the CC1310.
