Mar 5, 2025 · How to power the Arduino Nano with external power supply without the USB cable. There are two solutions using Vin and +5V pins.

Mar 10, 2025 · I have made a board as shown in the circuit diagram. There is no connection from 5 volts to either VIN or 5v pins on the Nano, but it runs happily without the USB connection. Is it possible that enough power flows through pin 10 (via SW1) for it to run?

Mar 21, 2017 · I've connected my USB cable to a USB-to-serial adapter, so it can communicate with the device. The problem I'm running into is powering the device: if I'm using the USB for serial, I can't use it for power.

Jan 18, 2014 · As well as using the serial-port (via an off-board USB to serial adapter) to program the Arduino-Nano, you can also program the on-board Atmega168/ATmega328 using ICSP. You need a programmer but you can use another Arduino for this (using the Arduino as ISP sketch), a bus-pirate or other devices.

May 10, 2020 · I power the NANO and the circuit using a 9V 1A wall wart and the PC usb cable. In this configuration everything works just fine. After I've programmed the NANO I've tried to remove the USB cable and the power led on the board turns off. 2 GND pins are connected.

Apr 10, 2021 · Is there any quick-and-dirty way to program it without a cable? like splitting an usb cable into individual wires and connecting them directly to the pins? SOLVED: cable was ok, I forgot to install drivers.

Oct 31, 2020 · In this guide, learn about Arduino Nano pin outs and diagrams. We’ve created a well explained, diagram based pin out representation of Arduino Nano. Arduino Nano Pinout. The Arduino Nano, as the name suggests is a compact, complete and bread-board friendly microcontroller board.

Feb 27, 2021 · The Arduino Nano doesn’t use a standard USB in order to connect with a computer; it comes with a Mini-b USB cable. Discover the Best Starter Kits with Breadboard. Arduino Nano has 14 digital pins and each of them can be used both ways: as input and output.

Mar 30, 2022 · Here is my new Arduino Nano board, This looks better with C-type and one step above compatible drivers. I faced many problems in making the PCB, but I think PCBWay is the solution to all of them with their PCB prototype capabilities. And looks of the pcb also matters, see this tiny cute beast.

Mar 28, 2013 · I am wondering if there is a way to upload a sketch to the board without using the USB connection? Something similar to burning a bootloader to it using another Arduino as ISP (which I have done before, and do have another Arduino which I can use for this purpose).
