Arduino Pro Mini (ATmega328P) – Price in India
The Pro Mini is a compact ATmega328P microcontroller board built for permanent, space-tight projects where a full Arduino Uno is too big. With the same 328P chip as the Uno, it is a favourite of Indian makers, students and product developers who need Arduino power in a tiny footprint.

Product Overview
The board has 14 digital I/O pins (6 usable as PWM), 6 analog inputs, an on-board resonator, a reset button and unpopulated header holes so you can solder only the pins you need. It has no on-board USB — you program it with an external FTDI / USB-to-serial adapter (sold separately), which keeps the board small and cheap.

How to Use / Program
Connect an FTDI or USB-to-serial adapter to the 6-pin header (DTR, RX, TX, VCC, GND, GND), select “Arduino Pro or Pro Mini” and the correct processor/voltage in the Arduino IDE, then upload your sketch as usual. Match the adapter voltage (5V or 3.3V) to your board variant.
Frequently Asked Questions
Does it have a USB port?
No — use an external FTDI/USB-to-serial adapter to upload code. This keeps the board small.
5V/16MHz or 3.3V/8MHz — which do I need?
Use 5V/16MHz for most projects; choose 3.3V/8MHz for battery or 3.3V-sensor designs.
Is it compatible with Arduino IDE?
Yes — select “Arduino Pro or Pro Mini” and the matching ATmega328P processor.
