Armbian showed a pictures of Orange Pi 3 Plus. Now, BananaPi released a pictures and info about BananaPi-W2. It is really powerful single-board computer. So, we can wait for two interesting a powerful single-board computers.
As I mentioned in title, it contains a lot of different interfaces.

The heart of board is Realtek RTD1296 processor, Quad-core ARM Cortex-A53 with Mali T820 MP3 GPU. More info about this processor, which contains Gbps ethernet, 2x SATA, 2x USB 3.0 you find here . The amount of RAM is 2GB and the type is DDR4.

If you have a device of about USB key size but you don´t need an USB connector, then the 1551 MINI series is right for you.

Paulo Bruckmann created Micro Soldering Station with Arduino Uno development board which contains ATMega328P.

The Autor wrote this Micro Soldering Station is very cheap...

The cnx-software website shared interesting news about clone of ATMega328P called LGT8F328P microcontroller by LogicGreen.

The manufacturer promises 99% compatibility with popular ATMEga328P microcontroller by Atmel/Microchip.

CZ.NIC which is known thank to popular and safe Turris Omnia router, introduced a new modular router which is called Turris MOX.

MOX is modular and open-source router where you can just buy only modules which you need.

Saleae, the manufacturer of logic analyzers, released a new beta version of PC software for showing of data waveforms.

The big advantage of this program is real-time showing of data - from digital inputs. In case that your logic analyzer includes analog inputs, the Saleae software shows also this analog waveform.
Andreas Spiess shared video on youtube where he compared ESP battery powered development boards.
If you check the video, you will find answers which you need during your choosing of board.
- Does the board use a shielded module or just a chip soldered on the PCB?
- How many pins are broken out to pin headers?
- Does the board come with an antenna connector for an external antenna?
- Is the board breadboard friendly?
- How clear is the pin labeling?
- Does the board have an additional “flash” button?
- Is a battery switch available?
- Which battery connector do you need?
- Does the board crash if you disconnect USB?
- What type of voltage regulator and LiPo management chips are used?
- How much current does the board consume?


STMicroelectronics released development board with STM32 and also LTE module Quectel BG96. The whole kit is called P-L496G-CELL02.
The development board contains ultra low-power STM32L496 microcontroller with 1 MB FLASH, 320 KB SRAM ...

The first article about Raspberry Pi 3B Plus described CPU benchmark, current consumption and also showed pictures from thermal imaging camera. Now, this article describes speed test of ethernet, WiFi 2.4 and 5 GHz.
The developers which are in touch with development of Raspberry Pi 3B+ declare the speed through ethernet up to 300 Mbps, but the ethernet connection is still through USB 2.0 converter. Is it real speed?
The Raspberry Pi 3B Plus board includes also WiFi module which supports 802.11 a/b/g/n/ac (2.4 and 5 GHz). What is the speed of WiFi?

I'm sure that you encountered with the situation when your code or part of your code didn't work as you wanted - operation with a few pointers, logic operations, conditions, parsing of value from long array etc.

If you have modern microcontrollers and development board which supports debugger (e.g. STM32 and Nucleo, Discovery) you can easily step (debug) your code in debugger.
If you don't have debugger, how do you follow values, variables? Are you using UART? Or LCD?
