Flexible-Input-Output
FlexIO system is under active development. our current efforts are directed towards PCB prototyping. As the development team is in the middle of examinations, development efforts have slowed down. We will pick up the pace after examinations are over.
FlexIO is a groundbreaking modular device ecosystem, predominantly designed to revolutionize user interaction and data sensing. It comprises FlexIO Node, a versatile user I/O hub, and FlexIO Sense, a cutting-edge sensor platform. FlexIO Sync combines the strengths of FlexIO Node and FlexIO Sense, delivering unmatched flexibility, seamless integration, and unparalleled adaptability for diverse applications, from automation to monitoring and control.
At the heart of FlexIO is FlexOS, a powerful and flexible firmware designed in MicroPython. Whether you're using FlexIO Node or FlexIO Sense, the core OS remains consistent, with modular components that adapt to the connected hardware. FlexOS simplifies app creation, making it accessible even to users with no electronics expertise, while retaining advanced capabilities for power users. Its dynamic architecture allows users to add or remove modules effortlessly, ensuring a tailored experience for various applications.

Few words from the creator
- FlexIO began as a learning project. At first, there was no clear purpose—just an ESP32, hardware, and Python scripts for experimentation. The breakthrough came when we successfully loaded external scripts, laying the foundation for what would eventually evolve into FlexIO.
- Initially, it wasn’t called FlexIO. Over time, the hardware and scripts naturally evolved into a modular system we now call FlexOS. This modularity became FlexIO’s core strength, allowing it to adapt to different hardware and use cases with ease.
- To extend FlexIO’s capabilities, we proposed FlexIO Sync, a system utilizing ESP-NOW for seamless communication between devices. This led to the creation of FlexIO Sense, a sensor-focused system, while FlexIO Node retained its I/O functionality. Together, these systems will form a powerful, interconnected ecosystem.
- FlexIO’s journey continues as we integrate more features and capabilities. By learning, innovating, and pushing boundaries, we aim to deliver a system that empowers users with simplicity, flexibility, and endless possibilities for their projects.
