New IP Camera OSHW board in design RFC

img2

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.

STM32-E407 Open Source Hardware board got ARM Mbed OS support

Screenshot from 2019-10-24 11-07-29

Arm Mbed OS is free, open source RTOS targeting IoT applications. It supports online IDE, many compilers and devices.

More you can learn on Mbed OS web page and the GiHub repository of the project.

Recently Rohan Fletcher posted on our forum that he add support for our STM32-E407 board in Mbed OS.

For these who are interested and want to give it try – here are his instructions how to use STM32-E407 with Mbed OS.

Open Source Hardware boards for NB-IoT technology presented at RuseConf 2019

nbito

RuseConf is part of IT-Tour. Every year IT-Tour organize conferences in Sofia, Plovdiv, Varna, Ruse, Burgas, Veliko Tarnovo. They are all made by volunteers and completely free to participate. The idea is to encourage local IT community to share ideas and interesting talks.

This weekend on 28th of September was RuseConf and Olimex presented there our newest NB-IoT boards.

NB-IoT-DevKit boards will be on our web for sale next week with sale price per one unit EUR 18.00. They employ the NB-IoT technology which uses existing LTE 4G network to implement LPWAN.

The NB-IoT devices use low power and can operate on battery for 10 years if network traffic is less 200 bytes per day (this may seems small but SigFox for instance allow 2 to 140 uploads of 12 bytes messages per day. NB-IoT has no restrictions and limits, but if have to be careful as more traffic means more battery discharge. One GSM LTE base cell can connect up to 100 000 NB-IoT devices at same time ( but of course it no one talk on his GSM phone in this cell range) which beats LoRa gateway maximal theoretical 49 connections. Also the NB-IoT module we use has +20dB more sensitivity so if normally one Base cell can connect to NB-IoT nodes up to 10km this module has 10 time more sensitivity and can connect up to 100 km from the base cell. This of course is marketing claim theoretical claim as explained in the talk but still impressive.

The slides are in Bulgarian and English and uploaded at Slideshare.com

 

ESP32-ADF Internet Radio example now uses LoBo with 2.8″ TFT LCD and touch screen

 

The Internet Radio demo for ESP32-ADF now includes MOD-LCD2.8RTP and LoBo for UI. Updated version is uploaded on GitHub.

OSHW High precision calibrated digital air quality CO2, temperature, humidity, air pressure sensor board with UEXT connector

MOD-ENV4

Analog gas and air quality sensors have quite negligent readings. They need special calibration to measure correctly.

This is why CCS811B digital air quality sensor by AMS is so interesting. It can measure indoor air quality and CO2 content with digital readings from 400 up to 29206 ppm.

MOD-ENV has CCS811B and BME280 digital precise temperature, humidity and air pressure sensor assembled together. Both operate through I2C and are low power with sleep modes which makes them perfect for enviroment monitoring and IoT.

ESP32-POE, ESP32-POE-ISO, ESP32-EVB has UEXT connectors and can directly connect to MOD-ENV.

The price of MOD-ENV is between EUR 14.36 and 15.95 depend on quantity.

ESP32-DevKit-Lipo, ESP32-POE and ESP32-POE-ISO boards now have option with external antenna and all our ESP32 boards can be build in extended temperature range -40+105C for demanding applications

ESP32-POE-ISO

Our popular ESP32-DevKit-Lipo, ESP32-POE and ESP32-POE-ISO now has option with external antenna, so you can use them even with metal boxes. The external antenna extends their range by 20-30%.

We stock now ESP32 modules with 16MB of Flash, so if you run out of memory you can order any of our ESP32 boards with 16MB Flash module too.

Also we have ESP32 modules in extended temperature range -HT (high temperature) which works from -40C up to 105C for demanding applications.

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

Screenshot from 2019-04-19 17-39-37

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

Screenshot from 2019-04-19 17-39-51.png

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

Screenshot from 2019-04-19 17-40-08

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!
