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

esp32-coreboard

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 🙂

Qualcomm with new dual band Low Power WIFI Solution QCA4004

qualcomm

The Low Cost WiFi revolution made by Texas Instruments CC3xxx and Esspressif ESP8266 is not escaped unnoticed by the big boys in the wireless business.

Qualcomm has new product QCA4004 which targets same market but has lot more to offer:

  • Dual-band 2.4 GHz/5 GHz
  • Low energy
  • IPv4/IPv6 Networking
  • SSL Client with AES encryption
  • RTOS and Toolchain for code on chip
  • USB 2.0,  SPI/SDIO, UART, HS-UART, I2C, 2xI2S, GPIOs
  • Commercial: 0 to 85˚ C (case) Industrial: -40 to 85˚ C (ambient) temperature grades

Here is the flyer and the datasheet.

So far the official quotes for the chip through the official distributors are high, but we know Qualcomm is leader in the wireless solutions and can manufacture efficiently, so once these get in main stream production the prices may drop below ESP8266 prices 🙂

 

Do button for IFTTT with ESP8266-EVB now you have endless opportunities to make receipts with the IFTTT tools

1

IFTTT is a web platform that facilitates connections between other big platforms under the form of recipes giving a great degree of flexibility in creating mashups. You can interact with almost  every social platform on the web like Facebook, Twitter, Instagram etc. For this purpose you make receipts like: If I get e-mail with picture on my Gmail account store the picture in my Dropbox and share it on Twitter, or etc.

Just a few days ago IFTTT launched a channel for makers.This was a highly awaited feature since until now it was impossible to connect prototypes to the recipes and only a few approved devices were available from large producers that were accepted in the platform. The Maker channel changes all that. It allows both making web requests to the channel to send events to other platforms from devices and from other platforms to the devices.

Constantin Craciun almost immediately add “DO” button with ESP8266-EVB and here is his tutorial.

You can see on this video how he uses ESP8266 to switch ON and OFF lamp via his phone:

Now you can think of endless apps for this DO button, like sending SMS “I’m home” to parents phones when the kid arrive from school and press the button.

Or button at the reception desk of hotel which send message to taxi company “go to hotel xxx to pickup customer”, etc. etc.

We are working on the small cloud broker for our ESP8266 IoT Firmware, and this IFTTT API will be definitely among the first implemented!
