- 電腦的 USB 埠
- 接入 5V /1A 的直流電源供應器
- 帶 USB 連接器的電源供應器
- 擴展連接器
電路板上的電源連接器為2.1 mm(內徑)x 5.5 mm(外徑)的筒狀電源連接器,中心為正極。
以下摘自 Beaglebone Black 手冊的電源部分。
The USB cable is shipped with each board. This port is limited to 500mA by the Power Management IC. It is possible to change the settings in the TPS65217C to increase this current, but only after the initial boot. And, at that point the PC most likely will complain, but you can also use a dual connector USB cable to the PC to get to 1A.
The power supply is not provided with the board but can be easily obtained from numerous sources. A 1A supply is sufficient to power the board, but if there is a cape plugged into the board or you have a power hungry device or hub plugged into the host port, then more current may needed from the DC supply.
Power routed to the board via the expansion header could be provided from power derived on a cape. The DC supply should be well regulated and 5V +/-.25V
