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.

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.

OLIMEXINO-328 special version of Arduino made for low power battery applications

Screenshot from 2018-01-09 12-21-46

Our friends from IrDroid made evaluation of OLIMEXINO-328 board low power modes and blogged about it.

OLIMEXINO-328 is special version of Arduino made for Industrial applications – It can be powered from 9 to 30VDC. The board has build in LiPo charger and step up convertor so when external power is applied or connected to USB the LiPo battery is charged, if both External power and USB connection is missing the power supply is automatically back up by the LiPo battery and OLIMEXINO-328 keep running from battery.

All components of OLIMEXINO-328 work in temperature range -25+85C.

Low power voltage regulators are used to board can be bring down to few micro Ampers when not active.

A20-OLinuXino-LIME server with 320GB HDD works on LiPo battery over 6 hours

A20-OLinuXino-LIME-1

We have server rack with several x86 servers running Linux with our work file repositories, the ERP and etc.

They are quite power hungry as lot of HDDs are connected to them in RAID mirrors to prevent data loss.

We are located in industrial area and power supply glitches are not uncommon, specially during the winter.

To keep the servers alive during power downs, we had to buy expensive 2000 EUR UPS, which actually keep them no more than 20-30 minutes up when power is down, so basically just to allow you 10-15 minutes to finish your work and then to shut them down properly before the battery is drained.

This UPS has lead-acid batteries inside which has to be changed every 3 years and cost almost as much as the UPS itself.

Initially we kept our all Olinuxino Linux images on Gdrive, but there were few issues with this, the images grew to many Gigabytes, and Gdrive start to restrict the access to the files after some limits were reach, so we decided to host these images by us on torrent. We decided to make separate server for this due to security reasons, we just wanted to keep our local network private and to allow external access only to this isolated server which we access also from outside like other users.

To keep it as low power as possible we setup one A20-LIME + HDD320GB + 6600mAh LiPo battery. This configuration works well several years already.

Yesterday our power supply provider EVN warned us that they will change mains high voltage cables in our area and Olimex will have power supply cut from 9.00 to 15.00, so we had to take day off.

We came today and sure we found all x86 servers down, but to our surprise the LIME with the HDD was working fine all these 6 hours of power blackout and didn’t shut down!

We know that with 6600mAh battery the LIME will last at least 10 hours as it uses 1.5-2W, but the HDD is rated 5W (5V/1A), so we were expecting less time stand alone operation.

It was good surprise to see that actual consumption is less, maybe the HDD enters stand-by mode when not used?

New Lower prices for Speedy Courier service to Greece

speedy_gonzales_by_trytonic-d8lhhd4

http://www.speedy.bg/ is the courier service we use for shipments inside Bulgaria. Speedy is 100% Bulgarian company and offers excellent service at good price. Their shipping system easily integrate with custom solutions including our internal ERP system and this allows us with singls mouse click to generate AWBs and call pickup with automatic filling of all necessary fields from our internal database.

About year ago they purchased Romanian courier company and start offering shipping from and to Romania and Bulgaria at the same price as the local prices, so it was same if you ship your order from Plovdiv to Sofia or Bucuresti.

This year they expands further and purchased courier company in Greece and from June 1st they do offer same local low cost prices to shipments to Greece too! If small parcel 0.5 KG before cost about EUR 11 to ship from Bulgaria to Greece, now it cost EUR 4.63

Keep the good work Speedy and please expand even further 🙂

FOSDEM-85 as thermometer with no external components

Image

Stefan Goetze submitted today cool project with FOSDEM-85 in our Project section.

https://www.olimex.com/Projects/

He is using the ATTiny85 internal chip sensor to measure the temperature, which he displays with LED blinks on Pinguino eyes. For this purpose he re-connected the Power LED to another port.

The document where he explains how he build it together with all source codes is here

Now FOSDEM-85 can be used as thermometer on your desk 🙂
