Arduino Pro Mini

Mini is a compact version of the Arduino board, ideal for smaller projects where space is a concern. It uses an ATmega328 microcontroller (the same as the Arduino Uno) but in a smaller, more efficient form factor.

Features of the Arduino Pro Mini:

• Size: Smaller and more compact compared to the standard Arduino boards, typically measuring 1.3" x 0.7".
• Voltage options: Available in both 5V and 3.3V versions.
• Pins: It has 14 digital input/output pins (6 of which can be used as PWM outputs) and 6 analog inputs.
• Minimal components: Lacks a built-in USB connection, so it requires an external FTDI adapter or USB-to-serial cable for programming.
• Low power consumption: It's a great option for battery-powered applications due to its low power draw.
