Here is a very simple breadboard power supply kit that takes power from a DC wall wart and outputs a selectable 5V or 3.3V regulated voltage. The .1" headers are mounted on the bottom of the PCB for simple insertion into a breadboard. Pins labeled VCC and GND plug directly into the power lines. The lone pair of pins have no electrical connection but help support the PCB.
There are two pins available within the barrel jack footprint. Any stripped +/- DC supply can be connected instead of the barrel connector. Board has both an On/Off switch and a voltage select switch (3.3V/5V).
Comes as a bag of parts kit and is easily assembled if you can follow the silkscreen indicators and have beginning experience with a soldering iron. You will need to read the resistor bands or use a multimeter to determine the resistor sizes.

這裡是一個非常簡單的實驗電路板電源套件,從DC牆上疣需要功率和輸出可選5V或3.3V穩壓。 .1“頭被安裝在PCB進行簡單的插入底部插入一塊麵包板。引腳標記VCC和GND直接插入電源線。孤對引腳沒有電氣連接,但有助於支持在PCB上。
有桶插孔覆蓋範圍內提供兩個引腳。任何剝離+/-直流電源可以連接,而不是圓柱形連接器。董事會同時具有On / Off開關和電壓選擇開關(3.3V / 5V)。
當屬零件包一包 ,很容易組裝,如果你能跟隨絲印指標,並與烙鐵開始體驗。您將需要閱讀的電阻帶或用萬用表來確定電阻的大小。
