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


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


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

Microsoft licensing corruption scandal in Romania has ended on October 3rd


This scandal covers buying Microsoft licensees for Romanian administration from 2004 to 2012 for total 228 millions USD.

During the investigation was found that more than 100 people, former ministers, mayor of Bucuresti and businessman are involved in this corruption scandal and more than 20 millions euro are paid as bribes.
The Romanian court ruled in March 2016 with sentences for 8 years of prison and 9 millions euro of asset forfeiture for the 4 persons on the picture.
These sentences were appealed and October 3rd the High Court of Cassation and Justice (HCCJ) confirmed the guilt and increased the sentences to 14 years in prison and 17 millions of euro of asset forfeiture for these same persons.

I have nothing to add but my admiration for the working Romanian Judiciary.

Bulgaria and Romania joined EU back in 2007 together and while Romanian people has will to change their future, the things in Bulgaria has very little improvements. In Romania there are near hundred of corrupted politics and public administrators in prison, in Bulgaria there are none. Supreme court in Bulgaria is overwhelmed with files, as everyone appeal his case for every small disputes up to the highest level. They have files which they have no capacity to review for next few years. So effectively there is no working Judiciary in Bulgaria. Тo judge someone here is just waste of money and time.

Bulgarian government spent almost 60 million of euro for Microsoft licensees from 2007 to 2011 and the “tender” winner is always one and same company.  I already posted about my wondering why such amount is spent for something with free alternative. Another question is why administration spends money for platform with 99% of all viruses existing and which is tool for US agencies to spy all around the world?

The information about Romanian corruption scandal was taken from here . I used Google translator so some numbers may be inaccurate🙂

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


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🙂

Qualcomm is buying NXP

Just one year after NXP bough Freescale, now they try to sell  to Qualcomm!

What is going on with this Semiconductor industry?

It’s long time not driven by engineering, innovations and products anymore, just shareholders and calculations what if we buy or sell this or that player in the field.

Qualcomm is well known name together with Mediatek they dominate mid-low end of the smart phone market, where Apple and Samsung share the high end.

Obviously their business is booming last years, they took also the Lion’s share of the tablet market where Chinese companies like Allwinner and Rockchip had some share, but the absence of RF in their SOC doomed them in the connectivity dominated world we live now.

What NXP can give to Qualcomm which they do not have yet is mystery for me. What will happen with Freescale and NXP products if Qualcomm buy them is also unpredictable.

Qualcomm do not publish any info for their products and they share just with few partners under strict NDAs. They are the opposite of how NXP and Freescale did their business so far with small users friendly approach.

What’s next? To promise to Qualcomm that will buy 100 000 pcs of future LPCxxx product to get the datasheet under NDA?

One is for sure imx.X is not going to be developed further as Qualcomm has plenty of competing products.
