Compatibility
This board is fully compatible with the Arduino Nano pinout, making it suitable for any Arduino Nano shields and modules. It works at 5V logic levels, directly interfacing with 5V sensors, servos, and displays. The CH340 driver is well-supported on Windows, macOS, and Linux, just install the driver for seamless IDE upload.
Wiring Notes
Connect the board via the included USB Mini cable to your computer. The CH340 chip may require driver installation on some systems. The Vin pin accepts 7-12V, but for USB power, simply plug in. Avoid drawing more than 40mA per I/O pin to prevent damage.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino IDE?
Yes, it works directly with Arduino IDE. Just select "Arduino Nano" and the correct processor (ATmega328P) in the board manager after installing the CH340 driver.
Do I need to install CH340 drivers?
Most operating systems recognize CH340 automatically, but if not, download the driver from the manufacturer's site. Once installed, the board appears as a COM port for upload.
Can I power it with a 9V battery?
Yes, you can connect a 9V battery to the Vin pin. The onboard voltage regulator will step it down to 5V. Ensure the battery can supply at least 200mA for stable operation.
