Dive Into the UNO SMD R3 Board – ATmega328P with CH340 | Ideal for Arduino Projects.
If you’re exploring the world of Arduino, robotics, or DIY electronics, the UNO SMD R3 Board powered by ATmega328P and equipped with a CH340 USB driver is your perfect companion.
Whether you’re a beginner building your first circuit or a hobbyist creating smart devices, this board delivers performance, compatibility, and affordability in one compact package.
🔍 What is the UNO SMD R3 Board?
The UNO SMD R3 is a variant of the classic Arduino UNO but comes with a Surface Mount Device (SMD) version of the ATmega328P microcontroller. This compact design makes the board more reliable for long-term projects and helps reduce production costs without sacrificing quality.
It features:
ATmega328P Microcontroller (SMD version) – the same processing power as the standard UNO
CH340G USB-to-Serial Chip – a low-cost alternative to the FTDI chip used in original Arduino boards
Operating Voltage: 5V
Input Voltage (recommended): 7-12V
14 Digital I/O Pins (6 PWM output capable)
6 Analog Input Pins
16 MHz Quartz Crystal
USB Type B Connector for programming and power
💡 Unlike DIP (dual inline package) versions, the SMD layout reduces the chance of pin damage or socket wear over time.
