#3084: Arduino Pro Mini Atmega328 (3.3V)

R149.00


The Arduino Pro Mini ATmega328 (3.3V) is similar to the 5V version of the Pro Mini, but it is designed to operate at a lower voltage of 3.3V. This means that the voltage level of the digital signals on the board are also 3.3V, which is compatible with many sensors and modules that are designed for this voltage level.

One of the main advantages of using the 3.3V version of the Pro Mini is that it is less likely to damage certain types of sensors and other components that may be sensitive to higher voltage levels. Additionally, the 3.3V version of the Pro Mini is often used in projects that require low power consumption, such as battery-powered projects.

The 3.3V version of the Pro Mini has the same pinout and can be programmed using the same Arduino IDE and libraries as the 5V version. However, the maximum voltage that can be applied to the inputs is 3.3V, exceeding that may damage the board.

You should be careful when connecting external components to the board, as connecting a 5V component directly to a pin on the 3.3V Pro Mini can damage the board or the component. In such case, you can use a voltage level shifter to convert the voltage level of the signal before it is applied to the board.

 

 

This is a 3.3V Arduino running the 8MHz bootloader. Arduino Pro Mini does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. We recommend first time Arduino users start with the Uno R3. It's a great board that will get you up and running quickly. The Arduino Pro series is meant for users that understand the limitations of system voltage (3.3V), lack of connectors, and USB off board.

This board connects directly to the FTDI Basic Breakout board and supports auto-reset. The Arduino Pro Mini also works with the FTDI cable but the FTDI cable does not bring out the DTR pin so the auto-reset feature will not work.
