New NB-IoT-BC66 modules with size only 26×26 mm contain everything you need to add NB-IoT functionality in your next project

NB-IoT-BC66d

NB-IoT is low power wide area networking technology which uses existing GSM LTE technology and has many advantages versa LoRa:

  • GSM network quality of service
  • single GSM cell can talk to up to 100 000 devices
  • high communication speed 25.5 kbps up and downlink
  • secure communication using LTE encryption
  • better range than LoRa both in urban and rural area (* depend on cell operating frequency – best range is om 850Mhz)

NB-IoT is already deployed in many applications:

  • Remote metering of electricity, water and gas;
  • Environmental monitoring;
  • City waste management, parking management, Lighting management;
  • Storage monitoring, logistics;
  • Healthcare patient monitoring;
  • Agroculture monitoring and management, remote irrigationi;
  • Industrial machinery monitoring and control.

The only disadvantage is the need of SIM card from operator, but in Europe there are many options for low cost SIM cards, to not make advertisement we will not quote but prices start from EUR 1 per year.

We add 4 new modules in stock:

 

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

esp32-gateway-gpios

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

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.

Open Source Hardware LIME2-SERVER user manual is uploaded and explains how to assembly and how to install Linux images of popular projects

LIME2-SERVERа

LIME2-SERVER is Linux server with only 2W consumption, A20-OLinuXino-LIME2 and option for HDD or SSD.

The server has bild-in LiPo battery which allow it to run for hours without external power supply, Gigabit Ethernet connection and power adapter 5V 2A.

Today we uploaded on GitHub the initial version of the user manual which explains how to assembly the boxes in case you didn’t bought it assembled.

Also basic instructions to use Ubuntu Bionic and Debian Buster images we provide.

KODI and NextCloud installation.

Additional info how to build and install Home Assistant, Yunohost, TOR server will be included in the next revision.

The LCD-OLinuXino Selection guide now includes the LCD panel dimensions and thickness information.

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

ESP32-DevKit-LiPo-GPIOs

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%

 

BC66 new firmware update fixes NETLIGHT bug

bc66

Our NB-IoT-Devkit popular platform is choice for many developers working on NB-IoT projects.

We got recently new firmware for BC66 which fix some bugs and add new functionality.

We are updating the firmware on all modules we have in stock now, but our customers who bought this board before can update their firmware with the image we placed on our ftp server.
