Nano V3.0 ATmega328P ImprovedCH340C Module with Built in 0.91 inchOLED Display Screen

Description

Product Overview

The Nano V3.0 ATmega328P with Built-in OLED is an innovative all-in-one development board that combines the familiar functionality of an Arduino Nano with a compact 0.91-inch OLED display. This integration eliminates the need for external wiring and breadboarding for simple visual output, streamlining your prototyping process and saving valuable space in your projects .

Based on the classic ATmega328P microcontroller and featuring the reliable CH340C USB-to-serial chip, this board maintains 100% compatibility with the Arduino ecosystem while adding a convenient built-in display. The 0.91-inch OLED screen with 128×32 resolution uses the SSD1306 driver and communicates via the I2C protocol, allowing you to display sensor data, system status, debug information, or custom graphics directly on the board .

Whether you are a hobbyist creating compact wearable devices, an educator teaching microcontroller concepts, or a professional developing space-constrained prototypes, this integrated board offers a sleek, efficient solution that reduces wiring complexity and enhances project presentation.

Key Features

• Integrated 0.91-inch OLED Display: Features a built-in OLED screen with 128×32 pixel resolution, driven by the SSD1306 controller via I2C interface. Pre-loaded with test firmware, the display works immediately upon USB connection .

• ATmega328P Microcontroller: Powered by the same 8-bit AVR microcontroller as the classic Arduino Nano, providing reliable performance and extensive community support .

• CH340C USB-to-Serial Chip: Utilizes the improved CH340C interface chip for reliable USB communication. Unlike older versions, the CH340C features an integrated crystal oscillator, reducing component count and improving stability .

• Breadboard-Friendly Design: Maintains the compact Nano form factor (approximately 45mm x 18mm), allowing direct insertion into standard breadboards with two rows of pins on 0.1-inch spacing .

• Multiple USB Interface Options: Available with Mini-USB, Micro-USB, or USB-C connectors to suit your preference and modern cable standards .

• Complete I/O Capabilities: Provides 14 digital input/output pins (6 with PWM capability), 8 analog inputs, and standard serial communication ports (RX/TX) .

• Flexible Power Options: Can be powered via USB (5V) or through the VIN pin with an external 6-12V DC power supply. The power source is automatically selected .

• Onboard Status LEDs: Includes power (POW), TX, RX, and D13 indicator LEDs for real-time visual feedback of board activity .

• Pre-Loaded Test Firmware: Ships with demonstration firmware that activates the OLED display upon first power-up, allowing immediate verification of proper operation .

• ISP Download Support: Features ISP (In-System Programming) header support for advanced programming options and bootloader recovery .
