问题描述
我无法找到的虚拟问题:我用来将 WiFi (802.11b/g/n) 添加到 Raspberry Pi 的屏蔽也可以在 Nano 上使用?
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?
换句话说:将 WiFi 添加到 Arduino Nano 板有多容易/可行?
In other words: how easy/feasible is to add WiFi to a Arduino Nano board?
谢谢！
推荐答案
Arduino 有多个 WiFi 扩展板，但如果您想使用 Nano 板，问题之一将是尺寸.有一些模块，但它们以 3.3V 逻辑运行，而不是 Nano 提供的 5V.
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.
我建议尝试 Arduino Pro Mini 3.3V/8MHz.请注意:
I suggest trying an Arduino Pro Mini 3.3V/8MHz. Please note that:
- Pro Mini 有两个版本:5V/16MHz 和 3.3V/8MHz(您需要 3.3V)
- 一根 FTDI TTL-232R-3V3 电缆，以便您可以对电路板进行编程.
在获取 WiFi 方面，ESP8266 最近备受关注.它非常便宜并且支持 802.11 b/g/n 协议.
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.
有关于将 ESP8266 与 Arduino Pro Mini 结合使用的教程和 Razvan Dubau 写了一个很好的指南，介绍如何使用 Raspberry PI
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
如果你真的必须使用 Nano 板，你可以使用电平转换器从 3.3V 逻辑到 5V.
If you really must use the Nano board, you could use a level shifter to go from 3.3V logic to 5V.
