The Azufier app pairs with the Azufier, an Arduino-compatible development board with AtMega32u4, which features a built-in BLE module. On the Azufier, there is a dedicated SPI port designed for you to connect an E-ink display or any sensor and turn your Azufier into a perfectly standalone IoT device.
Azufier app allows you to communicate or control your Azufier via function mode within the app.
