Arduino Uno R3的5V輸出電流
如題，Arduino Uno R3的5V輸出電流是多少呢?以下是官網針對電源供應作出的說明：
5V. This pin outputs a regulated 5V from the regulator on the board.
The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V).
Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. We don't advise it.
3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA.
這樣的話5V輸出的電流是取決於甚麼呢???
有最大上限嗎??
謝謝 當然是你負載的需求啊 V=IR
