Hi, all I have the Arduino UNO and try to activate a valve, therefor we have the MOSFET IRL540. On Gate we have the 0 or 5V signal from the arduino to switch (on/off), on drain we have 12V for the powersupply.
We designed a 4-channel MOSFET switch. It can supply up to four groups of electronic switches to control different circuit blocks respectively. Limited by the working priciples, MOSFET can only be used to control the DC circuit, such as DC-LED screen and so on, but not suitable for AC ...
插上插座PWRIN则一直有+5V主供电,当接上USBVCC(USB线)如果两边同时给+5V后端电路供电,理论上,PWRIN 大于6.6V,T1这个mosfet会关断,usb这个供电会被切断,如果<6.6V,两条通路同时输出5V,5V经过LP2985 这个带开关的LDO产生一个3.3V电压给插座,如果外围模块有用这个电的,可以从这里取电。 当没有PWRIN供电,只有US...
