M5Stack - stackabled development boards, which be useful for your development. This is description of M5Stack project in one sentence.

The main advantages of M5Stack are Arduino IDE library, whole project is opensource and M5Stack supports LCD.

The device contains one main board, now is it ESP8266, LoRa modul and 2" LCD.
You can buy a lot of boards to Core. For example wave generator and logic analyzer...

UP board or UP² (UP squared) board, these are familiar names of single-board computers.
UP team comming with kickstarter campaign for a new single-board computer called UP core.

UP core is designed for using a lot of GPIO's and peripherals, it contains 100-pin expansion board.

The processor is Intel® Atom™ x5-Z8350 (QuadCore 1.44/1.92Ghz 64 bit CPU), UP core comes with 2/4GB RAM, 32GB/64GB eMMC 5.0, 2 x USB 2.0 connected to pin header, USB 3.0...

SinoVoip company released a few pictures of BananaPi-T3 (BPI-T3). It should be designed for automotive application. Maybe infotainment (?).

UPDATE: BananaPi-T3 will not be on stock for hobby makers. T3 will be only customized for customer.

We can see a few info from pictures which are below. The processor is Allwinner T3 (quad-core Cortex-A7, and Mali400 MP2 GPU)....

We shared a few weeks ago the news about STM32L4 IoT development board. There are pictures of the board.

Olimex - ESP32-EVB.

You can find ESP32 WiFi&BT module built-in arduino programmer (USB-UART bridge), 100Mbit interface, microSD card slot, two relays (10A/250VAC), CAN interface

Other article about ESP32, with using of development board of SunDuino ESP32 and temperature/humidity sensor Si7021 (HTU21).

You can find up a lot of development boards for ESP32 on internet, some are cheaper, some more expensive.
The one czech hobby group (Robotika Brno - CZE) designed universal dev board for ESP32 (WiFi&BT).
The board called RB3200-ESP32universal contains Arduino uno rev.3 connector, power supply - 5V (USB) also 3.3V available on pin headers, LEDs, USB-UART bridge - CP1202 and a lot of pin headers for your sensors...
With ESP32 we can expect a lot of interesting board for wireless connections - WiFi and Bluetooth.
We expect that the Wemos name on the board is maybe abuse of name.

There are two of them. The first dev board contains ESP32, battery holder for 18650 battery, microUSB connector.
The price is $10.29 https://www.aliexpress.com/item/WEMOS-WiFi-Bluetooth-Battery-ESP32-development-tool/32814163663.html...

Friedlyarm released a new version of NanoPi single-board computer - NanoPi M2A.

NanoPi M2A is a new generation of NanoPi M2 by FriendlyElec, the new board responds to customer requirements.
NanoPi M2A combines NanoPi M2 and NanoPi M3.

The processor is the same like M2 Samsung Cortex-A9 - S5P4418 - quad-core up to 1.4GHz. Instead of M2, M2A contains WiFi 802.11 b/g/n and Bluetooth 4.0 module with internal antenna and connector for external antenna as well as NanoPi M3.

Arduino develops two new shields for LoRa IoT network.
The first board is Arduino LoRa Node shield used for Arduino Primo.
The second is Arduino LoRa Gateway shield for Arduino Tian.

I received very interesting board called WIDO. If you don't know this board, maybe the WIDO will be interesting after reading of this article.

WIDO board sent https://dfrobot.com store. Thank you very much.
For this article I used tutorial (wiki website) by https://www.dfrobot.com/wiki/index.php/Wido-WIFI_IoT_Node_SKU:DFR0321

WIDO - the board with WiFI module, which is compatible with Arduino Leonardo.

The article is on https://time4ee.com/articles.php?article_id=44

Adafruit released a new development board which supports JavaScript programming language.
This is other part of Espruino family like Espruino Pico or original Espruino.

The base components of Espruino WiFi board are STM32F411 (32bit ARM Cortex M4 @100MHz) microcontroller and WiFi ESP8266, wireless module with ESP8266...

ESP32 is the most anticipated component this year, we will meet with a lot of dev boards with this very popular chip for wireless workaround.

Freematics shared development board called ESPRIT with ESP32.

The board contains ESP32, Arduino Uno rev3 compatible connectors, 4pin header with I2C bus and 2x UART serial header.


SinoVoip released a new version of BananaPi M64. The processor was changed to Allwinner R18 - 64bit.
The new version of Banana Pi M64 is pin-to-pin compatible with previous version of that.
Other specs are the same....

Adafruit released a new development board with ESP32. That is not only one devboard, maybe you know these dev boards like SunDuino ESP32, Whitecat ESP32 N1 board, LoLin32 by Wemos or ESP-WROVER-KIT by Espressif.


Maybe you remember on news about the alternative to ESP8266 called RTL8710. Now is available a new development board with RTL8711AM - CREATOR Pro by RAKwireless.

The RTL8711AM integrates high-performance CPU, WiFi, Ethernet, peripherals like SPI, I2C and more. RT8711 can be easier implemented to Arduino with through Standard Arduino library...

Sinovoip, well-known like single-board computer manufacturer of Banana Pi, released other pictures of IoT module which uses NB-IoT (NarrowBand Internet of Things). This IoT network uses Vodafone in trial version in Czech Republic (2017).
NB-IoT is standard Low Power Wide Area Network (LPWAN) used for communication of IoT devices(Internet of Things)...

Do you know WhitecatBoard? It is other company which develops development board with ESP32. If you pay a little bit more you get ESP32 with wireless module for LoRa network...

Finally, I can write you a short tutorial how to play with ESP32 (more powerful than ESP8266). On the internet is a lot of tutorials how to do it, but this is a little bit different. I don't have LoLin32, Hornbill or ESP-DevkitC.
