First prototypes of ESP32-EVB-EA are ready, this is new version of our popular ESP32-EVB with external antenna

ESP32-EVB-EA

ESP32-EVB is our popular board, which allow things to be connected to Ethernet or WiFi/BLE. Many customers use them in their products and always asked how to put ESP32-EVB in metal boxes, so far the internal antenna made this hard to achieve.

Now we made new version with ESP32-WROOM-32u and External antenna. First prototypes are ready and we now do testings. New metal box similar to BOX-LIME is designing now:

Our goal is to have ESP32-EVB-EA with metal box enclosure by the end of August for sale.

ESP32-PRO IoT OSHW board with 4MB RAM, 4MB Flash, co-processor with USB-OTG 256KB Flash 64KB RAM is released

ESP32-PRO development started long time ago but with so many projects running in parallel it was always on the bottom of the priority list which was not quite fair for this board as it has excellent features:

32Mbit (4MB) PSRAM which maps on ESP32 memory space and can be used for your project.

32Mbit (4MB) fast QSPI Flash for program memory mapped to ESP32 program space.

Additional PIC32MX270F256DT processor with USB-OTG 256KB Flash and 64KB RAM which can be used as program or as USB profile like USB keyboard, serial, MIDI etc you name it.

ESP32-PROa

LiPo battery charger and management IC.

Optional Crypto engine for IoT applications.

We made two demo projects with this board which create WiFi to serial bridge you can pair two such boards and use them as wireless UART or Wireless USB Serial bridge, but the possibilities are many as the USB-OTG allow you to connect Web cameras, Flash drives and many other USB devices.

KiCAD 6 Donation campaign

Probably inspired by the successful Bootlin campaign for open source Allwinner VPU drivers, two days ago Maciei Suminski and Tomasz Wlostowski made Youtube video where they apeal for fund rising 30 000 CHF for the development of KiCAD v6!

Everyone can show their support for the most successful open source PCB design tool at:  https://givetokicad.web.cern.ch

More Tuxcon activities in Plovdiv

homeapp

Tuxcon is non for profit organization run by volunteers, with goal to promote open source technology in Plovdiv.

Once per year this organization make Tuxcon conference, but this year they didn’t stop with just this event.

In May they made with the help of Smarty Kids workshop for kids, where introduction to programming of Arduino and ESP8266 boards was present :

TuxCon 2018 was in June and had so many proposals for talks this year, that the two halls couldn’t accommodate them all.

So in July one separate event for Home automation was made with Miroslav Petrov.

mqtt

Miroslav talked about Domoticz and how to install it on A20-OLinuXino-MICRO:

Special tanks to the good people from Siteground for hosting this event.

This event attracted many people not only from Plovdiv:

For those who didn’t manage to come here is the Miroslav’s workshop web page.

What I hear is that the success of these events encourage the Tuxcon organizers to think about to make such every month 🙂 Keep the good work!

Tuxcon 2018 videos are now online

If you missed this event now you can watch all presentations and workshop in TuxCon Youtube channel.

BurgasConf is this Saturday 30th of June (of course in Burgas) looking forward to see you there

BourgasConf

BurgasConf is part of IT Tour – traveling IT events organized with the help of the local Burgas hacker space BurgasLab.

This Saturday it will start at 10.00 in Flora Expo Center.

Usually IT tour is focused more on Software than on Hardware, but this time we will try to change it a bit with Hardware related talk about the Flash memories.

These who come to the talk will learn about who invented the Flash memories, who are the major players and what are the trends. How the different Flash memories work, what we should know about how they wear and what precautions to take to minimize this, also are there security risks involved with their use.

We will not go in deep technical details, but enough to people learn what Flash memory is best for their application.

So looking forward to see you there!
