Arduino UNO SMD CH340G



Arduino Uno SMD is a microcontroller board based on the ATmega328P chip. It’s designed for beginners to get started with electronics and programming. The board has 14 digital input/output pins, six analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, and a reset button. Furthermore, the SMD version has surface-mounted components, making it more compact and efficient. It’s an upgrade from the through-hole version, being more reliable and easier to manufacture.

You can program the Uno SMD with the open-source Arduino software (IDE). This software is easy to use and has vast community support. You can use the Uno SMD for various applications, including robotics, automation, and data logging. In conclusion, the Arduino Uno SMD is a powerful and versatile board for beginners and advanced users. It’s user-friendly and perfect for learning and experimentation in electronics and programming.

Despite being a clone one, there is a pin group (4x GND, 2x 5 V, 2x 3.3 V, 1x RX/TX, 1x SCL/SDA) near to the crystal oscillator and there are external pin holes allow you to solder male headers on the board too.CH340G USB driver needs a special driver.
