This was an interesting board that I bought, I had been looking at D-Duino’s for a while wanting to buy them for a couple of project ideas. These boards are basically an ESP8266 and an OLED display integrated on one board, the main usage is for some terrific wi-fi examples that are present on the web.
The wi-fi examples come from https://github.com/spacehuhn , there is a couple of good ideas and projects them with interesting code examples to learn from
The thing here is this is not a D-Duino, its also labelled as a Wemos module – nope it’s not one of their boards either and this where the old worry comes in – have I been burned with another poorly documented clone board . So is it even an accurate clone of the D-Duino board – the good news appears to be a yes
The pinout below is correct, its a pin for pin match with the device I purchased, here is a picture of the D-Duino
Arduino Setup
You need to add ESP8266 support to your Arduino IDE
I selected a Wemos D1 R2 MIni in the IDE and the code I uploaded is from the section below
Code
I uploaded the Packet monitor example from the following location, some terrific examples this person has in his github repos. Not going to rip off his code here but take a visit
Links
There are a ton of links for these boards, the price ranges from about $15 to $20 from what I have seen
