Arduino Pro Mini 328 3.3V 8MHz

The Arduino Pro Mini 328 3.3V 8MHz is a compact and lightweight development board based on the ATmega328P microcontroller, designed for embedded projects where space and low power consumption are important. Running at 3.3V and 8MHz, it is suitable for battery-powered applications, sensors, wireless modules, automation systems, and compact IoT projects. Despite its small size, the Pro Mini provides the essential features of a standard Arduino platform, including digital I/O, analog inputs, PWM outputs, UART, SPI, and I²C communication. It does not include a built-in USB interface, so an external FTDI/USB-to-TTL programmer is required for programming. Key Features: Microcontroller: ATmega328P Operating Voltage: 3.3V Clock Speed: 8MHz Digital I/O: 14 pins Analog Inputs: 8 pins PWM Outputs: 6 pins Communication: UART, SPI, I²C Compact size: Ideal for space-constrained projects Low-power operation: Suitable for battery-powered devices Compatible with the Arduino development environment Applications: IoT devices, sensor systems, robotics, wireless projects, wearable electronics, home automation, and custom embedded systems.
