Microcontroller

The microcontrollers are designed for both offline and online operation of microfluidic, organ-on-chip, and organoid-processing systems. They support a broad range of peripherals, including peristaltic pumps, solenoid clamp valves, gas pumps, and devices interfaced through analog, serial, or RS485-12V ports. Each controller incorporates a compact control panel equipped with a mode switch, digital encoder, and OLED display for program selection, parameter adjustment, and command confirmation. A dedicated graphical user interface (GUI) provides an intuitive platform for managing tasks ranging from simple operations to complex, user-defined time-sequence control of all connected components.

These microcontrollers are highly compact and fully compatible with instruments using standard Modbus protocols. For biological applications, they can be safely placed inside a standard incubator, as neither cells nor culture media come into direct contact with any instrument components, thereby minimizing contamination risk. The schematic illustrates one example of the microcontrollers regulating multiple flow paths in a microphysiological system for automated experimental control.
