## HTML Description

🔧 Arduino Compatible Uno R3 DIP ATmega328P CH340 Board | AuscomTech

This Uno R3 compatible development board uses a removable ATmega328P in DIP package together with a CH340 USB-to-serial interface.

It provides the standard Uno-style layout with digital I/O, analog inputs, PWM outputs, ICSP headers, reset button, USB connection, DC barrel input, and shield-compatible expansion headers.

Typical uses include Arduino IDE learning, microcontroller replacement, bootloader work, sensor testing, robotics, automation, and general electronics prototyping.

⭐ Key Features

• Removable ATmega328P – DIP package allows the microcontroller to be replaced, programmed, or transferred into compatible standalone circuits.
• CH340 USB Interface – provides USB-to-serial communication for sketch uploading and serial monitoring.
• Arduino IDE Compatible – suitable for common Uno sketches, examples, libraries, and development workflows.
• Standard Uno R3 Layout – supports many Uno-format shields, modules, and expansion boards.
• 14 Digital I/O Pins – includes 6 PWM-capable outputs for motor control, LEDs, and other variable-output applications.
• 6 Analog Inputs – suitable for potentiometers, sensors, and analog measurement circuits.
• Flexible Power Input – can be powered through USB, DC barrel jack, or VIN.
• Shield-Compatible Headers – allows expansion using displays, relay modules, motor drivers, sensor shields, and other accessories.

⚠️ Important Notes

• This is an Arduino-compatible development board and is not an official Arduino branded product.
• This version uses a CH340 USB-to-serial interface rather than an ATmega16U2 USB interface.
• This listing is for the DIP version with a removable ATmega328P, not a fixed SMD microcontroller version.
• A CH340/CH341 USB serial driver may be required depending on your computer and operating system.
• Driver Download: CH340 / CH341 USB Serial Driver
• Use a suitable external power supply when operating motors, relays, or other higher-current loads.
• Input voltage above the recommended range may increase regulator temperature.
• Check pin usage and electrical requirements before stacking multiple shields.
