Arduino Uno的多种供电方式 电源选择电路的原理 描述 世界上最常用的开发板,Arduino Uno,支持多种供电方式,大致分为两类:5V直接供电与更高电压经LDO(Low Dropout Regulator,低压差线性稳压器)后供电。神奇的是,当两种电源都连接时,开发板会自动选择后者,而不会让两者冲突。
世界上最常用的开发板,ArduinoUno,支持多种供电方式,大致分为两类:5V直接供电与更高电压经LDO(Low Dropout Regulator,低压差线性稳压器)后供电。神奇的是,当两种电源都连接时,开发板会自动选择后者,而不会让两者冲突。完整的原理图可以在这里查看。由于整张图比较大,我把电源部分抽出来自己画了一遍。V1和VBUS分别...

Code: A000057 Similar to an Arduino UNO, can be recognized by computer as a mouse or keyboard.The Arduino Leonardo is a microcontroller board based on the ATmega32u4 (datasheet). It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), ...
在Arduino UNO R3 中,L7805 稳压芯片的 IN 口与 power jack 的正极之间加入 1N4007 二极管,其作用如下: 防止反接电源:阻止因电源正负极接反导致的电流倒灌,保护 L7805 和后续电路。 增强电路保护:避免外部故障或短路导致电流从电路倒流至电源适配器。
下面是5V、3.3V的通路,其中3.3V给外部模块供电,5V给UNO Rev3 C区和A区供电。VIN 二极管D1后端的一段电路输出,也就是NCP1117的输入端。 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...
