For first time customers to the OEMOS Flagship Store on AliExpress, they are currently offering a number of discounts and one of them is this development board based on the ESP8266 chip.

It is currently selling for around $5 (AUD) and they will give you a discount to make it cost only $0.59. But for some reason, AliExpress insisted on charging me $0.52 GST so the total price I paid was $1.11 (free postage from China). I ordered it last night and it was shipping from China this morning.

This board is in the Arduino Uno R3 form factor with the female headers and is compatible with Arduino Shields. However, the chip is different from the official Arduino; it is a lot more powerful and you get WiFi. I have never used it before but from what I understand, you just have to load the appropriate ESP8266 libraries to get your Arduino programs to run.

  I believe you need to be completely new to Aliexpress to get the welcome voucher. Existing Aliexpress accounts with history of purchases from other stores aren't eligible.

    No, my Aliexpress account is over 5 years old and I got the discount. Perhaps the seller operates a number of different stores and won't offer the discount if you already purchased from them?

    Since this was my first electronics component purchase on Aliexpress, I definitely never purchased from this seller before.

      When was your last order before this? If it's been a long time you're counted as a new user and get the discount.

      Full price is US$4.99 and SuperDeals price is US$3.24 ex GST.

        Previous purchase was a bag for paint brushes on 3rd June 2022.

          @ju2au: Over a year so that would be why.

  how did you get the discount? US$3.24 for me

• 

  Boioioioi on 07/06/2023 - 17:21

  Shows as $5 for me. Not worth it at that price, better off with an ESP32. Maybe deal is over?

    Deal is definitely still there. If you open the link below with a Web Browser that you don't often use or use the Incognito function in Chrome, you can see the deal:

      I can see it but once I sign in it goes poof

        ju2au on 07/06/2023 - 17:29

        I suspect that the seller runs multiple stores and you have already purchased from them.

•

  It is "Exclusive first order price" not "New Aliexpress Customers Only" so anyone can get it once.

  Intresting. once I sign in I cant see that price either despite it saying that.

  I'd really discourage getting an ESP8266 these days.

  Library support is patchy with it (and getting worse), too low computing capacity for a lot of applications.

  Go with an ESP32, better for most scenarios.

  This is not a financial advice, always take the label before reading the drug

    There isn't much more computation power in the esp32, 99% of the case you can chose either due to the nature of most job. The added advantage of Esp32 is more pin out without having to use extra module making it less clumsy design. If you need something more powerful then the pi path is the better choice.

      I'm not sure what a "pi path" is, but you clearly have no experience with either, so I'm not going to argue with you.

      I'll put it here though, for the greater good and all, that ESP32 boards* are dual-core, while the 8266 is single-core, which makes a huge difference in multi-threaded programming and the library support for that as well.
      Regardless of core count, the 32 is 3-4x faster than the 8266 (both on benchmarks and my personal experience, including uploading a new binary to test several times an hour).

      *mostly

        Not too mention the extra storage space in the esp32! Came here to say the exact same thing.

        So much compute for so little $$$$

        I was ruining into the limits of the 8266 with webserver and firmware update via the webserver.

        The esp8266 break out/dev boards (or better yet the esp1*!) Are an amazing board/chip though.

        I can't believe how much you can do with so little.
        And specially the footprint of them!

        if you don't know about the pi path then I doubt your credibility on the rest of the statement, only clueless teenager get fooled into the number of core or thread games created by Intel.

  If I log out I see the low price, log in and it's back to $5. At 1200+ orders I'm hardly a new user though, but I don't think I have purchased from these folks before.

    ShipShapeRC on 08/06/2023 - 11:32

    Just double checked, never purchased from oemos

  The WeMos D1 UNO R3 is a good board, and I've used it on many projects in the past. I then moved over to using the WeMos D1 mini as its form factor is amazing - which is why it's used in projects such as https://github.com/Qrome/marquee-scroller, https://awtrixdocs.blueforcer.de/#/en-en/hardware, and https://www.instructables.com/3D-Printer-Monitor-Wemos-D1-Mi…. Just need to be careful of clones as some are better made than others. Although it has more than enough memory and processing power for many projects, I'm moving over now more towards ESP32 boards just so I can have more GPIO pins (to support sensors and e-paper displays) although I will say that the wifi on the ESP32 seems to be a little more temperamental than the WeMos (R3 or mini) - not saying it's bad, just that in my experience it's not quite as good. Very much subjective opinion here of course, and perhaps I've just been unlucky with the boards I've got so far, so YMMV.

  In short, this is a good board to start playing with these sorts of things. Later you can decide if you need something smaller like the mini, or more power, or memory, or GPIO pins, or frankly if you need something that can be powered off some AA batteries for a year or two in which case you can go down the Arduino Pro mini route with a NRF24L01+ mesh network (eg https://www.mysensors.org/). It's a good time to be a geek. ;-)
