WiFi on Arduino Nano

问题:

Dummy question I was unable to find out: the shields that I use to add WiFi (802.11b/g/n) to a Raspberry Pi, could also be used on a Nano?

In other words: how easy/feasible is to add WiFi to a Arduino Nano board?

Thanks!

There are multiple WiFi shields for Arduino, but one of the issues will be size if you want to use a Nano board. There are a few modules out there but they operate on 3.3V logic, not 5V which is what the Nano supplies.

I suggest trying an Arduino Pro Mini 3.3V/8MHz. Please note that:

1. There are two versions of the Pro Mini: 5V/16MHz and 3.3V/8MHz (you'll want the 3.3V)
2. an FTDI TTL-232R-3V3 Cable so you can program the board.

In terms of getting WiFi, the ESP8266 is getting a lot of attention lately. It's pretty cheap and supports 802.11 b/g/n protocols.

There are tutorials out there on using the ESP8266 with the Arduino Pro Mini and Razvan Dubau wrote a nice guide on using this module with Raspberry PI

If you really must use the Nano board, you could use a level shifter to go from 3.3V logic to 5V.
