PRODUCT DESCRIPTION
The 3.3V Arduino Pro Mini ATMEGA328P operates at 3.3V with an 8MHz clock and utilizes an 8MHz bootloader. It features flexible connectors that can be soldered in any orientation or replaced with wires, offering customization for your projects. However, for beginners, the Arduino Uno R3 is recommended due to its user-friendly interface and more extensive documentation.
The Arduino Pro Mini is tailored for experienced users who understand the voltage limitations (3.3V) and the absence of onboard connectors and USB functionality. This board is perfect for those looking for a compact and efficient microcontroller solution.
Based on the ATMEGA328P chip, the Pro Mini includes 14 digital I/O pins (6 with PWM capabilities), 6 analog inputs, an onboard resonator, a reset button, and mounting holes for pin headers. It can be powered via a 6-pin header connected to an FTDI cable, providing both USB power and communication.
Ideal for semi-permanent installations in projects or displays, the Pro Mini comes with headers and is compatible with various connector types or direct wire soldering. Its pin layout also aligns with the Arduino Mini, making it versatile for different setups.
There is two versions of the Pro Mini. One runs at 3.3V and 8 MHz, the other at 5V and 16 MHz. To buy 5V/16MHz Pro Mini click on the name below
