Hardware Made Simple
Aillo is an open-source modular hardware platform that makes building electronic systems as simple as snapping blocks together. No soldering. No coding. Just plug, connect, and create.
How It Works
At the core of every Aillo system is a main board powered by an ESP32-S3 microcontroller. The board provides a grid of slots where modules can be placed.
Modules are self-contained circuits built around ESP32-C3 chips. Each serves a specific purpose — from buttons and LEDs to sensors and motor drivers. They connect via pogo pins and are automatically detected.
The Aillo mobile app connects to the board via BLE. Using a visual drag-and-drop interface, you design the logic — all without writing code.
