Arduino Uno R3 SMD Version (CH340 Chip)

The Arduino Uno R3 SMD Version is an Uno R3-compatible development board built around the surface-mount ATmega328P microcontroller, with a CH340 chip handling USB-to-serial communication. It has the same pin layout as the standard Uno, so it works with Arduino shields, libraries and tutorials, and it is programmed from the Arduino IDE. It is a cost-effective board for learning, prototyping and school projects.

Arduino Uno R3 SMD Version Specifications

• Microcontroller: ATmega328P (SMD package)

Arduino Uno R3 SMD Version Applications

• Learning programming and electronics
• Sensor, LED, motor and display projects
• Robotics and home automation prototypes
• STEM classes and university labs

What's in the Box

• 1 × Arduino Uno R3 SMD board with CH340 chip

Tip: If the board does not show up as a COM port, install the CH340 USB driver for your operating system, then select Arduino Uno as the board in the Arduino IDE. Each I/O pin should supply no more than about 20 mA, so use a transistor or driver module for motors and relays.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
