New Product in stock: ESP8266-EVB the ultimate Internet of Things development board


We now have in stock ESP8266-EVB.

It’s small 57 x 50 mm development board with MOD-WIFI-ESP8266-DEV board on socket, Relay 250VAC / 10A, button, UEXT connector, 0.1″ step connector with all ESP8266 signals. Power supply 5V jack.

The board price is EUR 9.95/ea

The demo code we work on now will create WIFI AP hot spot where you can connect with any device with WIFI capability, then from the web page you can switch on/off the relay, read the button status and send I2C or SPI commands. Small tutorial how to setup the GCC and SDK also will be blogged this week.

The button is with dual purpose, it’s general purpose button, but if it’s pressed during power up the ESP8266 will go in bootloader mode and you will be able to upload new firmware in the chip.

To upload code you will need any USB to serial 3.3V converter like USB-Serial-Cable-F which directly plugs to UEXT pins.

ESP8266-DEV can be powered with SY0605E.

    Guys, think more about SW support or DEMOS or at least INTRO. You are underselling this way your products. And I don’t talk about price, but about quantity. Cause – release date IS ONCE ! Next time it will be AN UPDATE – about the SW demo, intro or whatever. Seriously – you could’ve ask the community for support: give them few of this ready steady (stable :D) boards, they to write the EXAMPLE code,create a little hype by sharing (which is normal) their process of work. I like and even am proud of that Olimex is Bulgarian Company (as I’m Bulgarian) , but you are … sorry to say , and I hope you see the constructive critics here, FAR from Bulgarian thinking about products – release, support AND even advertising. I’m not expert in the last, but …. I can tell you – 1/10 people I work outside BG HAVE NOT HEARD OF YOU or YOUR BOARDS ! And after THEY DO like 50/50, i.e 5/10 want to try or buy to try your products. Simply – pls do it right, do it as ‘Big Pro’ Player/Company. After you follow the basics, create the image and do the services/products, etc you will get to there over time 🙂 But you have to start … thinking, acting, doing it like Big & Pro 🙂 Please at least TRY ! Thanks 🙂 And I know it’s a hard work, even harder than in rest of Europe, cause we are on the Balkans AND in Bulgaria 🙂 But I don’t think that has ever stopped you 🙂

    For FOSDEMers, there is gonna be an ESP8266 workshop this friday:

    Don’t know if there is gonna be time to get an EVB for the workshop, if not, maybe for an ESP8266 meetup during the FOSDEM?

    Waiting for the tutorial and the examples on how to program and use this jewel.

    Поздравления за новия продукт ! Какъв е вграденият процесор ? Как ще може да се програмира и какви от досега разработените (усвоени, тествани, разбрани най-накрая от разработчика 😀 ) програми ще можем да използваме ?

      “ESP8266 is very highly integrated SOC which includes Xtensa LX106 core processor, RAM, RF front end …”
      “Our module comes with installed 2MB of SPI Flash…”
      It should be programmable with GCC – we are waiting for Olimex examples but in the meantime you can browse the web and search for examples for programming ESP8266.

    Is the board already containing the ESP8266? Or does it have to be bought separately?

    Really a Powerful module! I can’t wait to receive my dev board to start playing with it! Please post as soon as possible some project examples…now I’m reading something about LuaLoader and NodeMCU firmware (and the esp-httpd mini webserver firmware)…I’m really excited! Thanks! 😀

    What are the pins of the esp board for Tx and Rx? I see no marking for this on the module. I do not have the dev board – it didn’t work, so I only have the mod-wifi-esp8266-dev module.

    It would be great to have on board power supplay so you can connect it direct to 230V
