Description
Pro Mini ATmega328P 3.3V / 8MHz Development Board
The board is based on the ATmega328P microcontroller and provides 14 digital I/O pins, 6 PWM outputs, and 6 analog inputs. It includes an onboard resonator, reset button, and mounting holes for pin headers or direct wire soldering, giving flexibility for custom installations.
A 6-pin FTDI header allows USB power and serial communication using an external FTDI adapter. The Pro Mini is intended for semi-permanent installations such as exhibitions, wearables, IoT devices, and automation projects. Beginners are advised to start with Arduino Uno, while this board suits intermediate and advanced users.

Customer Reviews
Once you've figured out that these are FTDI instead of USB, then you're going to need to hook it up. The attached photo might help you.
Thank you! Everything is OK, quality is very good!
When you program, I use FT232RL FTDI Mini USB to TTL Serial Converter Adapter. Keep in mind that DTR in FTDI should be connected to GRN or DTR in mini pro otherwise you will program ONLY once.
Works great in many applications.
Was absolutely identical to Arduino and worked correctly with no problem. It loaded up both test and final program without a problem. A reliable clone.
Looks good, arrived ahead of schedule and powered right up. I soldered on the pin headers and use a breadboard with an ArduinoISP to program it. No issues whatsoever. Great buy for a great price. Highly recommend it.
Had no problem so far uploading any of my sketches after I got the driver.
I love this format of the Arduino. I use it in all kinds of projects where space is a premium. Full functionality and lots of memory make it fast enough for what I need to do.
This board looks and feels exactly like it should. Works perfectly and is easily programmed to work with any compatible peripheral.
Awesom deal. Super fast shipping. A++
