WEMOS released a new development board with ESP32 called LoLin32 with price $4.9 (+ shipping, $2.59 in my case).

WEMOS has released LoLin32 a few weeks ago. Here is link to the news..

The Lite version of board is smaller, it also contains battery input, micro USB connector and reset button.

The most important news is version of ESP32

Friendlyarm is known for development of single-board computers and it released a new board called Nano Pi DUO.

Nano Pi DUO, which dimension of board is similar with NodeMCU (DUO 25.4 x 50 mm vs. NoceMCU 25 x 48 mm), contains Allwinner H2+ (quad-core Cortex A7), the same like Orange Pi Zero, 256 or 512 MB RAM DDR3, XR819 module WiFi 802.11 b/g/n with on board antenna as well as ...

A new example code for meteostation board. The first example code: ESP12E reads values (temperature/humidity) from Si7021 sensor and then the data is sent to tmep.cz website. This website shows values like chart.
The new example code: ESP12E also reads values from Si7021 and the values are showed on OLED display - 128x64px.
