Open Source Hardware IoT boards ESP32-EVB and ESP32-GATEWAY now are available in industrial grade -40+85C

ESP32-EVB and ESP32-GATEWAY are two very popular IoT boards which are supported both by Arduino IDE and Espressif SDK.

Now we stock ESP32-EVB-IND and ESP32-GATEWAY-IND which are functionally same boards, but all components used in them work in industrial temperature grade -40+85C.

ESP32-WROVER-DevKit-Lipo Open Source Hardware board with 4MB Flash and 8MB PSRAM is in stock

ESP32-WROVER-DevKit-LiPo is new open source hardware board which uses ESP32-WROVER modules with 4MB Flash and 8MB PSRAM.  It keeps same layout as ESP32-DevKit-C and ESP32-DevKit-Lipo, so boards made for these modules will work drop in.

The only difference between ESP32-WROOM and ESP32-WROVER modules beside the more RAM is that WROVER module has no GPIO16 and GPIO17 which are used internally and not connected to the outside pins.

ESP32-DevKit-LiPo Open Source Hardware board GPIOs table and power consumption testings – in deep sleep the board uses only 65 uA

Our ESP32-DevKit-LiPo board is pin to pin compatible with Espressif ESP32-DevKit, but we add to it LiPo battery charger, so the board can operate from LiPo battery like BATTERY-LiPo1400mAh

High resolution of the above GPIO map is available here.

Having LiPo backup power supply allow WiFi/BLE connected handheld devices to be created with ESP32-DevKit-LiPo.

In our new Revision B of this board which is on prototype stage:

If PWR_SENS_E1 jumper is shorted your software can monitor if external power supply is attached or you work on battery.

If BAT_SEND_E1 jumper is shorted your software can read battery voltage.

When operating on battery low power is necessary, so we optimized the design of Revision. C to reduce power consumption as much as possible and here are the results:

ESP32-DevKit-LiPo powered by Li-Po battery (no LED)

• normal mode: 35mA +/-10%
• deep sleep mode: 0.065mA +/-10%

ESP32-DevKit-LiPo powered by 5V USB (LED up)

• normal mode: 35mA +/-10%
• deep sleep mode: 2mA +/-10%

 

OSHW 2020 report State of Open Source Hardware – Olimex Ltd with highest number of registered OSHW projects :)

OSHdata published 2020 report about the State of Open Source Hardware and we are extremely proud to be #1 OSHW contributor at OSHWA certification directory.

There is another company from Plovdiv which is #7 – ANAVI Technology, congratulations Leon! You seems to be two positions ahead of Google LLC 🙂

New Product in stock: Metal box for A64-OLinuXino

BOX-A64-BLACK is metal box with PVC black coating for A64-OLinuXino

The box comes with all necessary fasteners for board assembly inside the box and four rubber feets.

Opening for external antenna is provided although current A64-OLinuXino revision has no WiFi module with U.FL connector inside. We work on next revision where this will be fixed and A64-OLinuXino board will be possible to order with internal or external antenna.

 

FOSDEM 2020 Bruxelles 1-2 of February OSHW room and soldering workshops

FOSDEM is this weekend and we will be very busy the two days!

Saturday 01.02.2020 at 10.30 will be my talk in “Open Source Computer Aided Modeling and Design devroom” “Designing and Producing Open Source Hardware with FOSS/OSHW tools”

Sunday 02.02.2020 at 13.00 will be my talk in “Hardware Enablement devroom” “Open Source Hardware for Industrial use”

The great news is that this year FOSDEM organizers let us have whole OSHW room UB4.228 where we will have two days Soldering workshops:

Saturday we will solder PTH components with special board we made for FOSDEM – FOSDEM-MUSIC-BOX

Sunday we will proceed with more advanced SMT soldering workshop of Binary-Watch

The soldering workshop participation is free as in beer and everyone is welcome.

We will bring with us limited number of 100 pcs FREE FOSDEM-MUSIC-BOX soldering kits for Saturday and 100 pcs FREE Binary-Watch soldering kits for Sunday.

We also will take with us soldering tools to equip 10 soldering seats. If you want to join and already have soldering iron, twizzers, magnify glass, wire cutters please take them with you and spare time on waiting on tail to get free soldering seat.

Also if you want to assembly some of our other soldering kits listed here (or any other boards) you can send us email at info@olimex.com with the boards/kits list you want to purchase and we will deliver to FOSDEM so you save shipping fee.

Lastly there will be plenty of space in the OSHW room, so if you have interesting project to show off or just want to chat about OSHW topic you are welcome, let’s make this room meeting point for Open Source hardware enthusiasts at FOSDEM.

FOSDEM 2020 – the must see EU biggest Open Source Technology event is approaching

If you work with Free Open Source Software and Hardware and you never have been on FOSDEM you don’t know what you are missing!

This is huge and every year becomes bigger. Join 8000+ hackers all around the world and watch your favorite talks – you can always find something interesting among the 480+ talks which will run during FOSDEM weekend 1-2 of February.

There you can meet lot of leading Linux and FOSS developers face to face.

I have two talks there:

• Saturday in Open Source Computer Aided Modeling and Design devroom
• Sunday in Hardware Enablement devroom

We are also promised dedicated Open Source Hardware room UB4.228 yay!

We are preparing special PCB and will run Soldering Workshop there

It’s music box, programmable with Arduino IDE, specially designed to be easy to solder by beginners.

As always the soldering workshop will be completely free (as in beer) to participate 🙂

In this room will be plenty of space and everyone who have interested in Open Source Hardware and want to come to show off something or just to chat is welcome.

So clear your agenda for February 1st and 2nd and book your flight to Bruxelles!

Looking forward to meet you there!
