The KTA-332 is a ESP32 Powered IO module for interfacing to real world applications. It's also an Arduino compatible controller and can be programmed with Arduino IDE for stand-alone operation.

A simple ASCII protocol allows control from Windows/Mac/Linux using either USB Virtual serial port drivers or RS-485. Additionally, multiple devices can be connected to one RS-485 bus, allowing control of many devices from one USB port.

Multiple controllers can be connected to one or more PCs in an RS-485 network. Each controller can be assigned an address and will respond to commands addressed to them.
