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...
晚上终于让她动起来了,程序是没错的,不用驱动板也是可以的,原来一直困扰我的问题,不是程序,而是独立供电,烧了一块uno,烧了一块2560,她们短暂的生命让我幡然悔悟,接下来的每一块板子,我都会温柔地对你们,感谢一直对我悉心指导大佬,不嫌弃我的追(bai)问(chi),民那桑,再次谢谢你们@反美游击队@fakogeeko@据点...
The Arduino Nano Every contains the ATMega4809, a more powerful processor than the one in the Arduino UNO board. This allows you to compile a more advanced program, as it has 50% more program memory than the Arduino UNO ATmega328P. It also has 200% bigger RAM than UNO. If you are us...

5V (on my 5V Nano at least). The voltage divider reduces the 5V to 3.3v and stops the world from being destroyed (or at least the RX pin on the HM-10). 5V Arduinos see 3.3v as HIGH so we can connect the HM-10 TX pin directly to the Arduino RX pin without destroying every...
Finally, we have the maximum valueadcMaxthe Analog Digital Converter (ADC) of an Arduino Uno can return. If you use a different Arduino or an ESP32 check the resolution of its ADC and setadcMaxaccordingly. For instance, ESP32 boards usually have an ADC with a resolution of 4096 steps, ...
