PlovdivConf is part of IT Tour great initiative, to make regional IT conferences in 5 big cities in Bulgaria: Varna, Burgas, Ruse, Veliko Tarnovo and Plovdiv. They make it every year and it’s made by the same team which organize the biggest Open Source event in Bulgaria – OpenFest in Sofia.

As Open Fest is huge and there are usually more talks applications than time (OpenFest is just two days)  IT Tour decided to make these regional conferences where local people has more chances to talk on IT subjects.

This year I will have lecture at PlovdivConf and will talk about “How Open Source technologies can help to make our city better place to live”.

Plovdiv municipality recently show interest in Open Source and we will try to help with our expertise and experience. The initial subject they are looking for solutions are: Parking management, City Lighting management, Waste management, Transport management, Bicycle management, and so on. We are already working on FOSS/OSHW solution for all these problems. They are open though to any other subjects which could help them to do their job better, so if you have idea come and share.

In my talk I will try to show the advantages of the Open Source solutions. Everyone is welcome to join the conference. It’s free to attend and we will looking forward to hear you and have after lecture discussions and ideas exchange how we can make our cities better place to live.

 

EDIT-25.09.2018: I’ve just uploaded the translated to English slides on Slideshare. Please pardon errors it was done in no time 😉

ESP32-EVB-EA Open Source Hardware IoT development board with ESP32-WROOM-32U and external antenna is in stock

ESP32-EVB-EA

Our popular ESP32-EVB now can be ordered with external antenna version: ESP32-EVB-EA.

What is next? Nice metal box, we already have first prototype:

It’s not painted and looks not so good but once we run production it will look as good as BOX-LIME-BLACK:

BOX-LIME-BLACK-1

Box production is scheduled for end of September.

ESP32-POE Open Source Hardware IoT development board with WiFi/BLE/100Mb Ethernet with 802.3 POE is in stock!

ESP32-POE-1

ESP32-POE board is now in stock. The prices start from EUR 14.36 for 50 pcs order.

This board offers Open Source Hardware / FOSS solution and building block for distributed sensor network with power over existing LAN infrastructure.

Possible use cases are Home automation, Industrial machine logging, remote environmental monitoring, access control, remote displays etc.

The board contains ESP32-WROOM-32 module with WiFi/BLE and Ethernet connectivity , RESET and USER buttons, micro SD card, LiPo battery charger and LiPo connector which allow board to work even with power supply drops.

The UEXT connector on the board can be used to connect many different sensors like:

Si3402-B chipset takes care for the power over ethernet, it’s IEEE 802.3 compliant, including pre-standard (legacy).

Important notice, to keep board compact and as it’s main purpose is to connect to cloud different remote sensors there is no galvanic isolation between board and the power delivered by the LAN switch or router.

ESP32-POE has internal programming interface and you can program it with Espressif SDK or Arduino via USB cable. As the board is not galvanic isolated from the Ethernet power supply, before you connect the USB cable to your computer you should remove the Ethernet cable or you should use USB-ISO between your computer the ESP32-POE!

New Open Source Hardware Color TFT LCD Display 320*240 pixels with Touch panel module for direct connection to ESP32-EVB via UEXT

MOD-LCD2.8″RTP is Color TFT LCD 320*240 pixel resolution with touch panel and connects directly to ESP32-EVB via UEXT connector with cable.

Now you can add fancy UI to your IoT projects!

 

New Board from Espressif – ESP32-LyraT in stock

ESP32_LyraT3

ESP32-LyraT is low cost IoT speech recognition board. It can work with many audio sources and have provisions to connect speakers, camera and LCD display.

The board documentation is skinny as this board is very new and we got limited quantity of one of the very first produced boards.

 

MOD-BME280 precise Humidity, Temperature and Pressure sensor Open Source Hardware module with UEXT and Breadboard connector

MOD-BME-u

BME280 is digital humidity, temperature and pressure sensor with I2C and SPI interface.

You can see on this link comparison of different Humidity sensors

The operating conditions are:

  • Temperature -40..+85C;
  • Humidity 0…100 % Rh;
  • Pressure 300…1100 hPa  (+9000m..-500m above sea level);

The sensor works on 3.3V and is with very low power consumption 0,1..3,6 uA.

The easiest way to connect MOD-BME280 is with UEXT connector to any board with UEXT connector as shown on the picture above.

For boards which has no UEXT connector MOD-BME280 can be connected via four jumper wires on breadboard:

MOD-BME280-b

The KiCad files are uploaded on GitHub.

The demo software use Adafruit BME280 libraries with two small modifications. The default address in MOD-BME280 is 0x76 while Adafruit library is set to 0x77.

UEXT connector requires D8 to be set LOW to power and 10 ms delay to settle the power before addressing the sensor. The code is at GitHub.

When you run it you will see this:

The sensor is very precise, if you move board up and down you can see altitude changes. The 171 meter is the altitude of Olimex building.

MOD-BME280 is perfect for IoT application for environmental conditions logging due to the low power consumption and precise measurements. It can be used both for indoor and outdoor applications.
