OLinuXino Open Source Hardware Single Board Linux Computers are now officially OSHWA certified

Ax0-OLinuXino-LIME-1

OLinuXino Open Source Hardware Linux Computers now are officially OSHWA certified. The first: A13-OLinuXino, A10-OLinuXino-LIME, A20-OLinuXino-LIME, A20-OLinuXino-LIME2, A20-OLinuXino-MICRO has their assigned OSHWA certification numbers, the others are to follow as the process takes time.

Searching the OSHWA directory only Beagle Bone and OLinuXino are officially certified.

If you need more memory and micro SD card for your Arduino project -OLIMEXINO-2560 is with 256K Flash and SD card on board

OLIMEXINO-2560

OLIMEXINO-2560 is Arduino Mega2560 like board which keeps ports conversion but adds UEXT connector to connect our wide range of modules and sensors, works on 5V and 3.3V, and has on board micro SD card for file storage and logging.

Power supply uses DCDC convertor with input range 6-15VDC when OLIMEXINO-2560 works on 5V and 5-15VDC when OLIMEXINO-2560 works on 3.3V.

TuxCon 2019 is coming on 8-9 June in Plovdiv, reserve these dates in your agenda and we are looking forward to see you there!

tuxcon

This year TuxCon Open Source Hardware and Software conference will be on 8 and 9th of June in Plovdiv.

This year the talks on 8th of June will be record numbers – 16 and will be held in 2 halls, there will be very interesting topics for FPGA, Home Automation, Car tuning, Linux, Robotics.

On June 9th there will be traditional soldering workshop in Olimex’s training building. We will have kits both for starters with just PTH components and for these who want to master SMD technology.

tuxcon-2

TuxCon is free to participate event, made by volunteers with aim to popularize the free and open source software and hardware.

SC1000 Open Source Pocket size Portable Scratch Digital instrument you can build by yourself and impress your friends

[rasteri] released small pocket size digital scratch instrument and the video above explains how to assembly one. A13-SOM256 is used inside with small PIC to sense the rotating plate position and potentiometers.

Looks like a fun project! We are very tempted to build one for ourselves 🙂

It’s Friday again and time for our Guess What is this Quiz

We just finished the routing of this new board, so the question is Guess what is it?

It uses Quectel EG21-G module which works anywhere in the world covering all GSM standards and frequencies. It also has GNSS build-in.

It also can connect to any network 2G-3G-4G whichever is available (sorry no 5G yet 😉 ).

Once the prototypes are ready and check we are preparing Crowd Supply campaign for it! Hint Fits perfect to LoRa-GATEWAY and allow connection where no wires and optics like mountain hubs, remote areas etc.

You can post here or retweet/share/boost on Twitter/Facebook/Mastodon/Diaspora and in Monday we will let Random.org to decide who will win one of our new eduArdu educational board.

Have a nice weekend!

UODATE 22-04-2019: Random.org selected @netsigi as winner!

 

Open Source Hardware ESP32-POE-ISO is now in stock and we are very proud with the result

ESP32-POE-ISO-2

We are very proud of our new ESP32-POE-ISO and delighted to announce it’s already in stock ready for order!

What we did with this improved version of the low cost ESP32-POE power over ethernet solution for IoT?

  1. As many requested we add 3000VDC galvanic insulation. Now you can program / debug while connected to PoE switch or router;
  2. Many asked for more GPIOs so we set SD-card in 1 bit mode and this way released 3 GPIO pins for other use;
  3. We got hints that new Espressif SDK allow ultra deep sleep modes for ESP32 and we re-designed the power supply part that now the ESP32-POE-ISO has consumption down to 200 uA (130uA of which are taken from ESP32-WROOM-32D module). The rest board without the module consumes just 70uA;
  4. As per your request now battery level has option to be monitored with the ESP32 ADC;
  5. There is External power detection option, so your software will be aware when run sole on battery and when have plenty of power.
  6. The Isolated DCDC we use is 2W and provides 400mA @5V, 100mA are reserved for the battery charge (available if no battery is connected) and 100mA are provided for ESP32, which leaves up to 200mA @5V for your additional circuit.

We love to listen to our customers and we did our the best to complete most of the requests we got with this new version.
