esp32-evbesp32-evb-2

ESP32-EVB is our new board with ESP32-WROOM32 module. It has:

  • ESP32-WROOM32 module
  • two relays 10A/250VAC
  • Ethernet 100Mb interface
  • LiPo charger and step up converter allowing ESP32-EVB to run from LiPo battery
  • microSD card connector
  • two user buttons
  • UEXT connector to attach different sensors and modules
  • 40 pin GPIO 0.1″ step connector with all resources of ESP32
  • 5V power jack
  • three mount holes

Now time to write some examples and if everything works to launch production.

The sale price will be EUR 22.00

Bitcoin price tracker with MOD-WIFI-ESP8266-DEV on Indiegogo

ticrthing

We got note that one of our boards MOD-WIFI-ESP8266-DEV is in the newly developed open source hardware product – Bitcoin price tracker

dwyasvjcn75xupzt2tvq

They are running now Indiegogo crowdfunding campain. We wish them success!

As being open source this product could be easily re-programmed to track price trends of other goods as well, like gold, silver, tin, why not DDR memory and Flash memory prices, and to give you alterts when the price go above or below given price point?

ESP32-WROOM-32 WiFi/Bluetooth module is in stock!

esp32-wroom32-1

ESP32-WROOM-32 modules are in stock now!

Again these are from the very first lot and with limited supply. To give chances to more developers to try them we will not allow more than 3 modules per order.

This module is good only if you develop your own board. For these who are not good with the soldering iron and SMD components soldering our advice is to wait for new supply of ESP32-CoreBoards or our own ESP32-EVB which will come with two Relays, Two buttons, SD-card connector, Ethernet 100Mbit and all signals on prototyping friendly 0.1″ step connectors.

Thanks for all who posted tips on our blog about ESP32-EVB feature wishlist!

EDIT: there was question on Twitter if these are original Espressif parts and why there is no FCC/CE markinig, my guess is that the certification is not complete, as it’s in the datasheet but not on module body. The modules come directly from Espressif, as you can see from reel label they are manufactured October 15th 2016 and one week later are in our stock for sale 🙂

ESP32-CoreBoard is sold out, ESP32-EVB design has started

esp8266-evb-bat-1

ESP32 is really hot, the first lot we got sold out for couple of days. If we didn’t put the restriction for one module per order it would be sold out in matter of hours, as people wanted to buy x5 and x10.

ESP32-WROOM-32 modules are shipped from Espressif and we wait them to arrive next week.

Meantime we started the design of our ESP32-EVB board.

What we think so far is to have these features:

  • power supply from 5V
  • LiPo charger and step up converter to allow un-interruptable power supply
  • Two relays 220VAC/15A
  • Two user buttons
  • UEXT connector to which you can connect many of our sensor UEXT boards, or to program the board with serial cable same way like ESP8266-EVB
  • status LEDs

With the two relays you will be able to switch on and off two different appliances.

With the sensors on UEXT you will be able to measure temperature, light, moisture etc. and log them.

The plan is to complete the design in October and start selling this board in November.

Our target is to release this EVB for EUR 15.00.

If you think we should add something else let us know.

ESP32-CoreBoard V2 is in stock

So anticipated ESP32-CoreBoard is now in stock!

We expect next week some quantity of just the modules ESP32-WROOM-32, they will be on web for sale for EUR 6.00/ea

First ESP32-DevKitC development kits in Europe will be in stock next week

esp32

We have good news! The first ESP32 development kits in Europe will be next week for sale in our shop.

The quantity is very limited due to the high demand Espressif still can’t fill all the orders they got, so we will got less than 100 to start with.

If your WiFi project needs to go to next level and you want WiFi +BLE in same package ESP32 is the right device for you.

The technical resources are here. Due to the limited supply we will not process orders in which basket is put more than one ESP32-DevKitC, please give chance to more people to evaluate 🙂

The price is EUR 17.00

OpenFest 2015 is 7 and 8th of November in Sofia

Screenshot from 2015-10-29 12-05-59

Next weekend in Sofia will be held the biggest event for Free/Open Source technologies in Bulgaria – OpenFest which is run every year since 2003.

Olimex is approved for talk and workshop yay!

The lecture is in Saturday at 17.00 o’clock and we will show what we have been working mainly this year:

“Physical computing and IoT with Open Source Software and Hardware”.

We will demonstrate how easy is to connect physical objects to Internet with our new ESP8266 boards, and our plug and play firmware which recognizes the UEXT modules connected to ESP8266 like: electricity metering, LED displays, Fingerprint sensors, door locks, relays, buttons. etc. We will shop how to display Twitter messages on LED matrix display, how to make door lock with fingerprint sensor, how to implement DO button for IFTTT directly with ESP8266 by secure connection with 2048bit encryption, and how to connect and switch loads and measure what energy they consume.

Specially for Open Fest we made our new WiFi enabled LED 8×8 badge. It contains ESP8266 and can be programmed to do lot of stuff, like to display all tweets with hashtag #openfest2015 or to display what are the lectures which run now and in which rooms by connecting to Open Fest program web page and extracting the necessary info.

WiFi-BADGE

Needless to say WiFi Badge is OSHW and all software project sources will be on GitHub (sorry still work on the software and can’t upload yet, we will do this early next week keeping the good developer’s traditions everything to be complete and debugged in the last minute 😉 ).

WiFi-BADGE-3

As you can see all ESP8266 GPIOs are exposed on this badge so it is good also for development board, power supply is done with single 1.5V AA battery only!

The workshop will be about SMD component soldering, we will bring some Binary Watch Kits with us and teach you how to solder your own Binary Watch. These who already have been at TuxCon do remember these watches:

Looking forward to see you there 🙂
