Arduino mini pro is the smallest Arduino model available in the market. Arduino pro pinout will be discussed in this post. We already discussed how to install Arduino IDE & How to upload the first code. Arduino mini pro pinout, specification, and programming will be discussed in this article.
This board is equally powerful as Arduino Uno, Mega, and nano. Arduino mini pro is the smallest and lightest bord. It is available in two variants Arduino pro mini 5v and Arduino pro mini 3.3v. here we are going to discuss Arduino pro mini pinout and other features.
Arduino pro mini has two variants 5v and 3.3v. The Arduino pro mini dimensions are 33×17, 8. It does not have any USB connector. Do not have any FTDI programmer. It has a reset button. And onboard voltage regulator. Almost every pin has in build pullup and pulldown resistors. That can be initiate using the software.
The micro-controller is used in Arduino pro mini 328 (Atmega 328p). It has 32KBytes Flash Memory, 1KBytes EEPROM, 2Kbytes internal RAM. It has 8Mhz clock Frequency in 3.3v variant and 16Mhz in 5v variant.
3.3v Clock Frequency
5v Clock Frequency
Arduino pro mini pinout
Arduino pro mini has almost the same pins Arduino nano or UNO have. It has a total of 14 digital pins and 8 analog pins. It supports serial communication, SPI, and UART protocols. Pro mini Arduino pinout is very simple
After discussing Arduino pro mini pinout. The next question comes in mind is how to program Arduino pro mini. For doing that we need an FTDI programmer that uploads the code from computer to Arduino pro mini 328p IC. FTDI programmer is not on the Arduino mini pro. So, we need an external FTDI programmer and connect it with Arduino mini. The connection is very simple to follow the diagram or table.

After connection open your Arduino IDE Go to Board>>select Arduino Mini. Verify and upload the code. Also, select the correct port.
