Welcome
Time4EE - news and articles about EE. Arduino, STM32, Raspberry Pi, Banana Pi, CHIP computer, ESP8266, AVR, IoT, SBC, Embedded Systems
 
 
 
 
This Orange Pi Zero article will be about how to run WiFi (after boot) for OS armbian.
What speed of WiFi and ethernet we can expect. I used speedtest for WiFi and ethernet. USB speed was measured for one big file and a few thousands small files.

We shared a few interesting products by Firefly team and now we have the imposant single-board computer by Firefly too.
The most powerful SBC with Rockchip RK3399

Rockchip RK3399 contains two types of processors dual-core Cortex - A72 and quad-core Cortex - A53. The GPU is used quad-core ARM® Mali-T860 MP4 which supports dual cameras...
 


FiPy, name of the new project by pycom. Maybe you know SiPy or LoPy.
What is it?
Development board which supports five wireless networks like WiFi, BLE, cellular LTE-CAT M1/NB1, LoRa and Sigfox.
The ESP32 is main component in ...
 


Another very interesting kickstarter project called Badgerboard. That's LoRa® devel board with Arduino compatible pinout.
The team say that the radio range is from 1 to 3 km in urban area, up to 10 km in open area.
What Badgerboard contains?
The main component of devel board is ATMega32U4 microcontroller by Atmel Microchip. The wireless module was chose ...
 
The Sixfab Raspberry Pi IoT Shield Family was made specifically to add connectivity to your IoT projects. You can now connect wherever and whenever without the need for a wifi network or ethernet cables. With our added capabilities, the IoT Shield Family will also work with other devices, not only the Raspberry Pi.

New program for programming of Arduino. Alternative to Arduino IDE.
Maybe you know another IDEs like PROGRAMINO, PlatformIO or Eclipse . Now you can check CODINO.

On the homepage, is written about autosave function, highlighting, auto completing and another features.
CODINO also contains serial inspector - terminal and plotter.

CODINO is IDE, which is 100% free to using.

CODINO is NOT multiplatform. Available is only windows version.

Homepage of project: http://codino.businesscatalyst.com/

Notes:
CODINO doesn't know "go to declaration" and another advanced functions as Arduino IDE
CODINO needs Arduino IDE for uploading of the code
 
Well, here is another article about Orange Pi Zero. I would like to write these articles similar like for CHIP computer.

So, in this article I write something about power consumption by Orange Pi Zero, what is temperature of Orange Pi Zero and at the end I show you results of benchmark sysbench.

Orange Pi Zero - power consumption, thermal imaging camera, benchmark
 
Maybe you heard about Orange Pi. The cheaper clone of Raspberry Pi, but do you know Orange Pi Zero? This version is no such "cut down" like Raspberry Pi Zero.

As I wrote on social networks, I took a pictures of STM32H7 which you could see on Electronica 2016.

If you don't know what is STM32H7, check this news: http://time4ee.com/news.php?readmore=146

My ferric chloride was saturated and so I couldn't etch. I looked for equivalent, but I found something so much better.

I found very interesting video here.
But some etching bath are very unstable or/and dangerous - e.g. hydrogen peroxide with hydrochloric acid - it excludes chlorine.

Microchip released a new group of microntroller with AVR® core.
That are microcontrollers with up to 20 MHz clock, up to 8 KB FLASH, up to 512B SRAM and 128B EEPROM.
The packages are available with 14, 20 and 24 IO pins.
The microcontrollers offer better management of low power modes and peripherals, includes Event System and touch controller QTouch®.

After my experimentes with NodeMCU and SHT75 I designed next version of my mini meteostation.

I designed own PCB for plastic box. I chose the same ESP8266 module which is in NodeMCU, ESP12E.
SHT75 temperature/humidity sensor is expensive (but very accurate), so I chose another temperature/humidity sensor. Si7021 by Silicon Labs company.

Next generation of UP board unveiled.
UP board is single-board computer with really high power.
So, what hardware we can expect?
 
You can download a new version of Programino IDE for Arduino.
Add new features, fixed bugs.

I shared news about kickstarter campaign of codebender, Online IDE for Arduino, which promises support of ESP8266 and ESP32.
This campaign ends 2016/10/26. The goal is $60 000, but the campaign has only $6 000.
Petr Stehlík shared post about codebender.cc and the end.
Codebender writes on website, that "All good things must come to an end".
It has almost 100,000 registered users, 10,000 monthly active users and $800,000 of investment.
Another information in our website: https://codebender.cc/next-chapter
 
STMicroelectronics released a new microcontroller with ARM® Cortex®-M7 core.

STMicroelectronics changed technology of STM32H7 from 90 nm to 40 nm. Then the maximal frequency is up to 400 MHz. STM32H7 got 2010 point (856 DMIPS) in CoreMark.



To optimize the STM32H7, its architecture has been divided into three domains. Very simply, the first one (D1) includes the core with its cache, Flash memory and high bandwidth peripherals like the module to drive a screen or the Chrom-Art graphics engine. D2, the connectivity domain, groups low-speed peripherals like USB, the cryptographic accelerator and the SD/MMC2 unit for storage.
 
Interesting, NodeMCU shared news about ESP32 support and development of ESP32 development board on social networks. The news is here.

Development of NodeMCU is stopped. Very popular project of development board and firmware for ESP8266 . Makers announced that on social networks and project website. Firmware and documentation still be available.

Dear maker,

We're very sorry. NodeMCU has stopped further development of a new development board. And discontinued making new hardware.
The community will updated the NodeMCU Firmware and Documentation.

Yours sincerely,
NodeMCU Team.


Firmware of github.
Documentation.
 
We wrote a news about NEC company, which shared picture of their display with Raspberry Pi 3 compute module, after that raspberrypi.org shared another information about RPi3 compute module on their blog.
Now, the world can see datasheet of versions 1 and 3. What is suprise is that Raspberry Pi 3 compute module will be available in two versions!
CM3 - Compute Module 3 and CM3L - Compute Module 3 Lite

What can we find in datasheet?
RAM will be the same for both versions LPDDR2 (1 GB, its maximum), the processor will be BCM2837 (64bit quad-core).

CM3 version contains 4 GB eMMC FLASH, however CM3L doesn't contain eMMC memory. CM3L contains only interface for microSD card through IO expander...
 


NEC company shared the news about the latest 40" displays. Surprisingly shared picture of new Raspberry Pi compute module 3. From news: "However, the latest Raspberry Pi 3 compute module boasts significant performance and networking capabilities, making it perfect for NEC’s displays."
So, when we can expect the Raspberry Pi compute module 3? I think ...
