Arduino Power Supply Shield的电路图和原理图非常简单,并且不包含太多组件放置。我们将使用 12V DC Barrel Jack 作为整个 Arduino UNO Shield 的主电压输入。LM7805将12V 转换为 5V 输出,同样 LM317 将 12V 转换为 3.3V 输出。LM317是流行的稳压IC,可以用来搭建可变稳压电路。 为了将 12V 转换为 3.3V,我们使用...

This power supply module is designed for your Arduino UNO. It comes with an output of 100mA – 2000mA and an input of 100~240V). It has an extended cord of 100cm. The connector size is 5.5×2.1 mm. It has been certified for short circuit protection, automatic overload protection, and...
I half understand the Arduino Uno power select circuit that uses as p-FET to disconnect the USBVCC when an external Vin is supplied, but one bit baffles me. If no external supply is connected then at startup what state is the p-FET in? If the p-FET is ON (Vgs -ve) then USBVCC ...
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...
Arduino Uno ATmega328具有32 KB闪存(其中0.5 KB被启动加载器占用)。它还具有2KB SRAM和1KB EEPROM(可以利用EEPROM库读取和写入)。 Arduino Uno可通过USB连接或者外部电源供电。外部(非USB)电源可以是AC-DC适配器,也可以是电池。通过将2.1mm中心正极插头插入电路板的电源插座即可连接适配器。电池的引线可插入电源连接...

我们看上面的图片,一边连接电脑,一边连接Arduino Uno Rev3 电路板。电脑上打开下面这个程序,将编写的程序代码写到板子上。 基本数据传输过程如下:在电脑上Arduino这个软件内写代码-->点烧写程序-->程序代码通过USB线写到电路板上。程序烧写步骤细节后续再讲。我们这次需要明白的是:C区域ATmega16单片机作为一个中转站的...
The Arduino Uno board can be powered via the USB connection or with an external power supply. The power source is selected automatically. External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-pos...
