OBJEX Link is a modular IoT board. It is designed to develop IoT devices that are easy to repair and recycle. It is also perfect for rapid prototyping and developing research and robotics projects.

This library enables you to use Interrupt from Hardware Timers on an ESP8266-based board. It now supports 16 ISR-based timers, while consuming only 1 hardware Timer. Timers' interval is very long (ulong millisecs). The most important feature is they're ISR-based timers. Therefore, their executions are not blocked by bad-behaving functions or tas…

🛝 Starter learning kit for Arudino Nano / Uno and ESP32 DevKitC by RoboticsBrno.

An "Off-line machine learning" (Offline AI, artificial intelligence) project, in which 2 tensorflow-lite apps are developed to run on Raspberry Pi 3. It hopes to propose a generic method on cross-developing, so that developer could fast follow to get your own apps started on Embedded intelligence (AI embedded system), smart object (AI IoT) and etc.
