Nano ATmega328P Board with I/O Expansion Board
Product Details
Overview
The IoTCrazy Nano is an Arduino Nano 3.0 compatible board redesigned around the ATmega328P. It keeps the pinout and dimensions of the original — just 45 × 18 mm — so it drops straight into existing Nano projects, but at a fraction of the price of the official board.
It carries 32 KB of flash and 2 KB of SRAM, with 14 digital I/O pins (6 of them PWM-capable) and 8 analogue inputs. Programming and power both run over a modern USB Type-C connector, and the headers arrive pre-soldered, so the board is ready for a breadboard the moment you unpack it.
Built with laser electroplating and precision soldering, it is a dependable everyday board for robotics, home automation, IoT nodes and classroom work.
Key Features
- Premium build — Laser electroplating and precision soldering for a durable, clean finish
- Excellent value — A fraction of the price of the official board, with no compromise on the essentials
- Compact — 45 × 18 mm, ideal for tight enclosures and space-constrained builds
- Versatile I/O — 14 digital pins (6 PWM) and 8 analogue inputs
- USB Type-C — Reversible connector for programming and power
- Pre-soldered headers — No assembly needed before your first project
- I/O expansion board included — Breaks every pin out to labelled 3-pin servo-style headers with its own power input, so sensors and servos plug straight in
- Arduino IDE support — Programmed in C/C++ with the full Arduino library ecosystem

Good to Know
This board uses the CH340G USB-to-serial bridge. If your computer does not detect it straight away, install the CH340 driver first — our CH340 driver installation guide covers Windows step by step.
Please note: the CH340 driver for this board is not supported on Apple M-series (M1/M2/M3) Macs.
