Pro Mini ATmega328P

The Pro Mini ATmega328P is a compact and cost-effective development board based on the ATmega328P microcontroller, the same chip used in the Arduino Uno. It's a great choice for projects where space is limited or cost needs to be kept low.

Key Features:

• Microcontroller: ATmega328P (same chip as Arduino Uno)
• Operating Voltage: 3.3V or 5V versions available
• Clock Speed: 8 MHz (3.3V) or 16 MHz (5V)
• Flash Memory: 32 KB (0.5 KB used by bootloader)
• SRAM: 2 KB
• EEPROM: 1 KB
• Digital I/O Pins: 14 (6 provide PWM output)
• Analog Input Pins: 8
• No USB port (programmed via FTDI or USB-to-Serial adapter)
• Dimensions: ~33mm x 18mm

Typical Use Cases:

• Embedded systems
• Battery-powered devices
• DIY electronics projects
• Robotics (where space is tight)

How to Program:

Since the Pro Mini lacks a built-in USB interface, you’ll need an FTDI adapter or USB-to-Serial converter. The process is simple:

1. Connect FTDI to the Pro Mini:

• TX to RX
• RX to TX
• VCC to VCC (match voltage version!)
• GND to GND
• DTR to DTR (for auto-reset during upload)

1. Select the correct board and processor in the Arduino IDE:

• Board: Arduino Pro or Pro Mini
• Processor: ATmega328P (5V, 16 MHz) or ATmega328P (3.3V, 8 MHz)

1. Choose the correct COM port and upload your sketch.
