Embedded World 2018 is next week in Nürnberg


Embedded World is next week in Nürnberg. It’s good place to see many semiconductor vendors at once.

This year is interesting to see Chinese companies like Espressif Systems and Rockchip to  exhibit there. I look forward to meet there face to face people I have communicated only by e-mail!

Some interesting booths I put in my “to visit” agenda:

  • Analog Devices GmbH 4A-629
  • Arm Limited 4-140
  • ASIX Electronics Corporation 3-310
  • ATMEL – Microchip Technology 1-500/510
  • Broadcom Limited 3A-135
  • Espressif Systems 3A-623
  • Intel Corporation 1-338
  • NXP 4A-220
  • ON Semiconductor 4A-260
  • Qualcomm 4A-330
  • Realtek 3-341
  • Samsung 3A-438
  • Silergy 2-458
  • Silicon Labs 4A-128
  • SIMCom 3-531
  • STMicroelectronics 4A-138
  • Xilinx 3-311

Olimex used to exhibit at Embedded World three years 2014-2016, but in 2017 and this year we are just visitors. The reason for this decision is that Messe Nürnberg obviously has so much work and can’t offer good service for the smallish exhibitors. They make agreements then break them whenever they want and bear no responsibility. In our case February 2016 we made booking for exhibiting in 2017, Messe Nürnberg offered us booth plan and we choose booth with good location. We made agreement and then in July 2016 someone offered them to pay more for the same location and they assign this booth to them and notified us to go whistle. They offered us to choose from what’s left not booked or we can break the deal and we will not PAY COMPENSATION to them! This really pissed me off enough to decide to not exhibit there anymore. For the three years while we were exhibiting it was always one and same story: we order booth and arrangement and when we go to the show we see that they did something different, we complain then they do last minutes updates to fix the problems… For me it was shock to see things like this in Germany, which everyone praise for punctuality and precision. First year I said to myself oh well things like this happen, second year I though ok we just have bad luck, but when the third year the situation didn’t improve I though something is not right.

Otherwise Electronica, Productronica, Embedded World are among the very small amount of still very active exhibitions in EU. All local electronics exhibitions in our Balkan area like the Fair in Plovdiv, Thessaloniki, Belgrade, Istanbul are with declining functionality. They used to be very important events where people learn about new products and can make contacts, now internet made them less useful.

Hackaday conference in Belgrade 26th of May


First Hackaday conference outside US was held in Belgrade/Serbia in May 23rd 2016.

It was very interesting event with lot of talks and good food and drinks.

This year there will be second conference in May 26th again in Belgrade/Serbia. If you wonder why all Hackaday conferences are at one and same place the secret is that Hackaday owner Supply Frame Inc CEO is from Serbian descent, Hackaday have team and development lab setup in Belgrade, so it’s native choice.

Serbia did not join EU yet (hopefully this will happen soon!), so this is not so good news for EU travelers. While I could book my ticket for FOSDEM with Ryanair Plovdiv-Bruxelles and Bruxelles-Plovdiv for EUR 9.95 in each direction (Plovdiv – Bruxelles is 2300 km distance) , there is no such option for Belgrade and normal flight cost EUR 200 although Belgrade is just 550 km away from Plovdiv. This is the magic of the European Union single market and air space! Another issue is the roaming taxes in Serbia are ridiculous and cost something like EUR 3-5 per minute, while all telecom operators roaming charges in EU are less than EUR 0.15 per minute, so be careful when talk in Serbia with cell phone or buy local SIM card.

Hackaday has opened proposals for lectures and start selling early bird tickets for EUR 23.45 I guess this odd number come from $30 converted to USD/EUR exchange rate.

For this event Voja Antonic made special badge in the form of BASIC computer, so with the ticket you will get this beauty:

ESP32-GATEWAY the lightweight version of ESP32-EVB is now in stock! It’s with dimensions only 50×62 mm and is practically same as ESP32-EVB but without relays, CAN and IR control.


ESP32-EVB in stock!


ESP32-EVB is finally in stock 🙂

The size increased to 75 x 75 mm and these are the features:

  • ESP32-WROOM-32 CE/FCC approved module
  • Bluetooth LE, WiFi connection
  • Wired 100Mb Ethernet connector
  • micro SD card
  • two RELAYS 250VAC/10A (125VAC/15A) with LED status
  • CAN interface
  • IR remote control receiver and transmitter 5 m  range
  • RESET and USER buttons
  • USB micro connector for programming and power supply
  • LiPo battery charger and step up converter with 4 STATUS LEDs
  • Power jack 5V power supply

This is great board for IoT as has access to many interfaces: Ethernet, CAN, BLE, WIFI. The relays can switch power appliances. With the IR remote control you can control any device with IR like TVs, VCRs, Air conditioners, Sound amplifires, CATV etc.
