Arduino Unois a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection,
我们的核心是Arduino Uno开发板,下面这张图是Arduino的电路图。我把它的几个大块标记出来,下面我一一来说明下。 Voltage Regulator: 它的任务是为系统提供稳定的3.3V和5V的电压。在蓝色区域有两个voltage regulator,一个是LP2985,输入5V,输出3.3V;一个是NCP1117,输入最高20V,输出5V。Arduino的供电有两种,一种是U...
AREF. Reference voltage for the analog inputs. Used with analogReference(). Reset. Bring this line LOW to reset the microcontroller. Typically used to add a reset button to shields which block the one on the board. Communication The Arduino Uno has a number of facilities for communicating with...

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...
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。
