Compact ATmega328P Module, V3.0 Core and I/O: ATmega328P microcontroller with 32KB flash memory and 14 digital I/O ports in a breadboardfriendly form factor for versatile electronics projects. Modern connectivity: CH340 USBtoserial converter with a USBC connector, enabling seamless use with contemporary computers and supporting programming environments such as Processing and Max/MSP. Flexible power: Three power options for flexible operation—USB power, VIN (5V12V DC), or external 5V input—suited for both prototyping and standalone deployments. Expanded I/O: 8 analog inputs (A0A7), 6 outputs (D3/D5/D6/D9/D10/D11), and TTL serial communication, enabling sophisticated sensor interfacing and motor control for interactive projects. Use scenarios: Education and prototyping: quick setup on a breadboard for sensorbased experiments and learning projects. Small robotics and Actuation: drive motors or actuators via the 6 digital outputs with straightforward TTL serial communication. Interactive installations: integrate with Processing or Max/MSP for data visualization, control, and user interaction.
