Our Belgium distributor MCHobby made nice tutorial about how to program ESP8266-EVB board with microPython.
The tutorial is available also in French.
New Product: Optical Fingerprint sensor SNS-FINGERPRINT adds fingerprint recognition to your next project

SNS-FINGERPRINT is optical fingerprint sensor which will make adding fingerprint detection and verification very simple. Inside there is DSP chip that does the image rendering, calculation, feature-finding and searching. You can teach the sensor for fingerprint images and up to 1000 images can be stored in the internal Flash memory. There’s a red LED in the lens that lights up during a photo so you know its working. In image search mode the sensor compare the current scanned image with the stored database and if images match it sens index number of the stored image which match the current scanned fingerprint.All communication is done by UART.
ESP8266 IoT firmware plug and play detects if SNS-FINGERPRINT is connected to UEXT uart so you can make wireless door access system very easy using just Javascript programming. We also have demo in Arduino C++ and OLinuXino Python3 so you can access this sensor with any of our development boards.
Python modules for access to GPIO, I2C and SPI to all OLinuXino boards and SOMs on GitHub

We made modules which work same way on all our OLinuXino and SOM boards. The sources are on GitHub.
You can address the GPIOs in two ways – as connector pins and as processor ports.
connector.gpio1p5 means connector GPIO1 pin number 5, same signal can be addressed with port.PG0
