SparkFun ESP8266 Thing(Dev Board) + Arduino Uno?

Wireless & IoT Wifi
1

Hi,

First time posting.

I was wondering if it’s possible for an Arduino Uno to connect with the Thing (from https://www.sparkfun.com/products/13799) so that the Arduino Uno would have wifi connection for an upcoming IoT project.

I looked up the hookup guide (https://learn.sparkfun.com/tutorials/es … okup-guide) but it doesn’t seem to contain much details on connecting it with an Arduino Uno.

Thanks

Hi TFinito,

The SparkFun ESP8266 Thing is meant to work as a standalone development board so pairing it with an Uno to add WiFi capability to it is a bit overkill. I would recommend either using the ESP8266 Thing as your microcontroller or if you need to use the Uno, you may want to consider using just the bare [ESP8266 WiFi Module. Keep in mind, the ESP8266 operates at 3.3V logic and the Uno runs at 5V logic so you will need to level shift the serial connections between the two boards.](WiFi Module - ESP8266 (4MB Flash) - WRL-17146 - SparkFun Electronics)

Hi, thanks for the reply!

Do you know of a guide that would allow me to connect an Arduino Uno to the ESP Dev Board? I don’t want to buy more stuff and I want to use the Uno (non-wifi version) for an IoT project with Arduino modules/parts but I need it to have wifi.

Hi again,

I’m afraid we do not have a guide for connecting those two boards. You would need to send whatever data you are trying to get over WiFi from the Uno through the ESP8266 Thing Dev Board and then transmit that data to WiFi. Just like the WiFi module, the ESP8266 Thing Dev runs at 3.3V logic so you would still need to shift the serial signals from 5V on the Uno to 3.3V on the Thing Dev.

The ESP8266 WiFi Module would be the easiest option here as there are multiple tutorials available on sites like [Instructables and [/url=https://www.hackster.io/]Hackster.io.](https://www.instructables.com/)
