Open Source Software OpenMQTTGateway got initial support for Open Source Hardware ESP32-GATEWAY

OpenMQTTGateway project aims to concentrate in one Gateway different technologies like Bluetooth, LoRa, IR, lagacy RF 433/315, GSM/GPRS based devices and connect them with OpenHAB, Home Assistant, Jeedom, FHEM, Domotic etc platforms via MQTT protocol.

The list of the supported devices is long.

With recent PR initial support for ESP32-GATEWAY is add.

We got note from friend that our PIC32-Pinguino is on the cover of Belgium artists Phillipi & Rodrigo – “Gueto De Gent” Vinyl album. The genre is Electronic/Disco. You can hear it here:

 

Maybe the authors are also Makers and like to make electronic projects?

 

Build your own CPU and tools for it like Assembler, High level language compiler, simple OS, then write Pong game on it using only open source software and hardware. Check nand2tetris-13 project with iCE40HX8K-EVB + MOD-LCD2.8RTP + IceStorm

pong

Michael Schröder sent us link to his project nand2tetris-13 yesterday.

He managed to build his own CPU, to write Assembler, Jack high level language, OS and then write Fibonacci demo and Pong game. All this done on Open Source Hardware FPGA  board iCE40HX8K-EVB with MOD-LCD2.8RTP as display and FOSS tools IceStorm project. Keyboard is done by UART but my guess is that it could be easily implemented by iCE40-IO .

This is perfect project to teach students about so many things: Combinatory Logic, Sequential Logic, Computer Achitecture, Machine code to Assembler, High level language Compilers, simple OS and so on.

And the best here is that you can see this working on hardware not just boring lectures. Student can experiment with their own CPU and write applications like small games etc.

The Industrial grade -40+125C Open Source Hardware Linux board which is hardware compatible with A20-OLinuxino-LIME2 but with ST Microelectronics STM32MP1xx SOC STMP1-OLinuXino routing is complete

TOP1

BOT1

STMP1-OLinuXino routing is complete. It took 6 months from the idea to the finish.

Why it took so long? We had several times to re-design the schematics around the DDR memory and power supply.

Our goal was to make it pin to pin compatible with OLinuXino-LIME2 and we achieved it.

STMP1-OLinuXino has:

  • Same size as LIME2
  • Same GPIOs on same places
  • Ethernet, USB, battery Lipo, buttons, HDMI, SD-card on same places
  • same mount holes
  • 1GB DDR3 memory
  • Gigabit Ethernet interface
  • HDMI interface
  • LCD interface
  • 2x USB hosts and 1x USB-OTG
  • micro SD-card
  • GPIOs have similar interfaces on the same positions
  • LiPo battery charger and step up converter for battery operation
  • CAN interface

There are few differences:

  • we add Flash connector where different flash modules will be attached: NAND Flash, SPI Flash, eMMC Flash, so instead to keep many different versions of the board with different Flash options like LIME2 this will be done with exchangeable modules
  • we put the STM32MP1 SOC on bottom where adding heatsink do not interference with the top GPIO connectors and add-on boards

The STM32MP1 devices work at -20/40+125C operating temperature by default which makes them perfect for industrial applications.

There will be different versions with STM32MP151/153/157 as they share same BGA package, also there will be some versions with commercial temperature grade components for lower cost.  Our preliminary estimations are the prices to be between EUR 35 and 70 depend on the different configurations.

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

ESP32-WROVER-DevKit-Lipo

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.

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

frequent-creators

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 🙂

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

Screenshot from 2019-12-17 10-49-24

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:

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

We are preparing special PCB and will run Soldering Workshop there

FOSDEM-MUSIC-BOX_RevA_black

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!

S3-OLinuXino OSHW IP Camera update: board routing complete, next to-do prototype.

Screenshot from 2019-12-03 08-44-18Screenshot from 2019-12-03 08-45-48

S3-OLinuXino is now completely routed and we make prototypes to verify everything is well designed. If the prototypes are OK production will follow in Q1 2020.

New IP Camera OSHW board in design RFC

We started recently new design with Allwinner S3 SOC.

The board have these features:

  • Allwinner S3 Cortex-A7 running at 1.2Ghz
  • AXP209 PMU with Lipo charger and step-up for UPS
  • internal 1Gb DDR3 RAM at 1333Mhz
  • 100Mb Ethernet interface with PoE option
  • NAND/eMMC/SPI Flash on socket
  • WiFi / BT module with RTL8723BS
  • Audio In and Out
  • UEXT connector
  • Lipo battery connector
  • Configuration EEPROM
  • LCD connector for LCD-OLinuXino
  • MIPI camera connector with RPi pinout
  • CSI camera connector
  • Dimensions: 60 x 50 mm

S3 SOC is on bottom so heatsink could be add if overheating due to the small PCB area.

We want to build intelligent camera solution which can be powered by PoE and can work with both wired and wireless Ethernet connection.

We add MIPI camera connector with RPi pinout as there are plenty of cheap 5Mpix cameras available.

We also will provide CSI camera with 5-8Mpix separately.

Why we do this board? We want to have intelligent IP camera among our tools and we put features which are necessary to fit our potential projects. This board have also potential for Voice over IP , Video over IP, Security, Home remote monitoring etc.

Initial upload on GitHub is with our schematic and components put on PCB locations, routing is ahead, so we would like to hear your opinion.

Did we forgot something?

Can we do something differently or better?

Let us know what do you think.

RT5350F-OLinuXino-EVB now have micro SD card

RT5350F-EVB-1a

The new revision C of RT5350F-OLinuxino-EVB now has micro SD card which could be used for storage.

The newest images from our ftp server supports it.
