[Solved] NEW Arduino UNO WiFi board

Oh yes, absolutely. We’re just not that far along yet. We are merely looking for a easy to replicate prototype to widen our field testing, which is why we’re still looking for off the shelf options.

I’ve seen an Arduino Mega board with integrated ESP (attached to serial port) on one board. They are not very cheap (think 25 bucks), but they look like a nice board to develop stuff on. It’s this: http://www.ebay.com/itm/222305385421 thing

You can set the connections with jumpers. E.g. wether USB<> Serial is attached to Arduino or ESP or something else. I’m hoping I’ll receive this soon for testing. Looks likes a very nice all-in-one solution for developing. Only thing missing is an Ethernet port integrated :wink:

Check this one…

ATmega2560 R3 Mega WiFi ESP8266 (8 Mb de memoria), USB-TTL CH340G. Compatible para Arduino Mega, NodeMCU, WeMos ESP8266
(from AliExpress Android)

Yeah, I found that too, but allas, I don’t have a CC, so I cannot buy at Ali :frowning:

I’m using Blink on a wemos D1 mini with no problems. I would like to use Blynk on my Arduino Uno board with w51000 shield for Wifi connection, seems to a bit harder to do. Any help doing this would be great! Thanks!


That looks like a very interesting board. When you receive it, will you please report back and let us know how well it’s working with Blynk?


Good find, even cheaper! Have you used one, any idea how well it works with Blynk?

I’ll definitely report back. I’d like this for my main domotic system. I had all sorts of loose wires in there from ethernet and wifi and so on :smiley:

This saves a lot mess.

The DigiStump Oak can be utilized with the Arduino IDE. It has the WiFi you want and DigiStump has a Blynk library included with the Oak Arduino libraries.
The current level of the firmware has stabilized the WiFi connection and mine has been sending me Temp + Humidity data via Blynk for about 15 days since I last updated everything.
DigiStump has both 3.3v Relay shield and a level Shifter 3.3 to 5V shield to facillitate interfacing to 5 V devices. The Oak accepts 5 V in and provides Vin and 3.3V Vcc outputs.
DigiSTump Oak or cruise the Wiki or the forums: [Forums]

I have used virtual pins, read analog in, virtual LEDs for status etc in controlling a Hi Fi remotely via Android app. The Oak is 1/3 the size of the UNO but the shifter shield in a bit larger than the Oak.
Other shields are available.
Certainly meets many of your needs as a rapid functional prototype candidate. Fairly cheap too.


So far it’s a nice board, but I already bricked it by f-king up the bootloader … when it worked, it worked fine, but ESP as a shield had a high latency when connecting (450ms or so).

@Lichtsignaal presumably you can unbrick it?

I don’t know. It gives back “Invalid signature” when I try to load a new bootloader onto it (with another Mega2560 as ISP). I’m trying to find out if I can load a Sketch onto it wthout the bootloader, so if you got any bright ideas … I’m at a loss at this moment.

The Arduino Uno WiFi board is now confirmed as working With Blynk following a library hack as per post 40 of the following thread [Solved] Arduino.org Uno WiFi board with Firmware 1.0.0 and WiFiLink.h Librairies

It’s only works with the new firmware 1.0.0 and WiFiLink Librairies
Not Arduino-wifi-dev Librairies and firmware 0.82

@Emmanuel_Leroy do you have links for version 1.0.0 of the firmware and the procedure for the flashing?

the link of firmware is in my first post.

And i ve reedit for flashing procedure.


Thanks @Emmanuel_Leroy

Did you manage to make this work? Im stuck because I don’t get any output after flashing the sketch. Any ideas? Thanks.


Please read through the last few posts above, and their relevant links…

Do not tack a “me too” issue onto another topic!

If you are still having issues after some studying, then please create your own “Need Help With My Project” topic and supply DETAILS of what you have done and any errors, etc.

Thank you.
