This is your best source of “how to” documentation. Documentation varies from very good to “what documentation?” HOWEVER, there are example sketches in almost every library and once installed exist in the IDE menu. The Arduino community is a great source of help and sketches.

USB power - 5V from your serial connection, protection diode drops it to 4.7V working. 7Vdc – 12 Vdc but ideally why make it drop a lot of power? ~ 8-9Vdc raw is ideal.

Elegoo Nano Pinout Software Doesnt Have This article discusses about the. Power in - input before onboard regulator and protection. This Arduino NANO Pinout diagram reference is a handy guide for using this. +3.3V to drive external chips and sensors OK to use if you have a very good regulated 5.0V supply. If you read carefully, all is clear but here are many power pins. I hate to go more than 50% of rating, but an existing design drives a 27mA pin (continuous, 24x7) and runs totally cool. The pins drive an absolute maximum of 40mA. The Elegoo clones also work very well, but cost more.Ĭareful with pin current. I bought clones off Amazon that came assembled on a board with header pins. This is almost always required on MACOS, sometimes on Windows.

But in reality “Pin 2” for a digitalRead is in fact the 6th pin from the origin on the DIP packageĩ0% of the non-genuine Arduinos you buy will use a different USB/serial chipset (“CH340”) and demand the driver for that chip. Silly me, i thought if i defined “Pin 2” as an input, and connected a PCB trace to the 2nd pin on the DIP package it would work. Espressif produced a limited number of programmer / debugger boards. This allows abstraction so on sketch works on UNOs, NANOs, Mega, …but fouled me up but good for a while. The Arduino Uno pinout guide includes information you need about the different pins. Rather, in the sketch, pins take on different numbers depending on the function (digital, analog, GPIO, …) you are using them for. Pay attention.Ĭorollary to that: don’t do what I did! The physical pin numbers 1-30 are not how you define pins in your sketch. Physical pins are numbered traditionally, beginning in the corner with P1, and working your way up one side and back down the other, 30 in total. These are NOT THE SAME as the IC pin numbers when plugging a NANO (on soldered headers) into a PCB. They have various sets of nomenclatures by which you refer to pins when programming - eg “D11” or “A2”. Note that arduino pin numbering can be ambiguous. I’d be careful to get them from known sources, such as major supply houses, or he Arduino forums. Many thanks to “ #BlackCoffee” who,along with others on the Arduino forum, helped me along.Īrduino schematic and PCB library elements are out there and work great. An unfortunate exception to this is the official product page of the Nano, which does use physical pin. Where it says '8', it means Arduino pin 8, or the pin on the Nano marked 'D8'.
I thought i would add some information that i learned along my path to working with Arduinos in general and Nanos as embedded parts of a KiCAD PCB in particular. Almost always, when you see references to pin numbers in the Arduino world, they are talking about the Arduino pin numbers.
