Usage & Features
The Nano V3.0 board with the CH340C chip is a very small, complete, and breadboard-friendly microcontroller board, designed for independent operation in compact electronic devices or as part of projects requiring interaction with software on a computer.
- Prototyping: Its small size makes it perfect for fitting into tight spaces in prototypes or final projects without needing a dedicated DC power jack.
- Education: As it is compatible with the Arduino IDE, it is widely used in learning electronics and programming.
- Connectivity: The CH340C chip and Micro USB connection allow for easy programming and power supply directly from a PC or power bank.
- Power Flexibility: Power can be supplied via the Micro USB port, the VIN pin (unregulated 6-20V), or the 5V regulated pin (pin 27), with automatic selection of the highest voltage source.
Q: Do I need to solder the pins myself?
No. This specific product includes welded (pre-soldered) pins, meaning the headers are already attached to the board for immediate use on a breadboard or for direct connection to wires.
Q: Will this work with the standard Arduino IDE?
Yes, this board is compatible with the Arduino IDE. You will need to select the “Arduino Nano” board type within the software.
Q: Do I need to install a special driver for the CH340C chip?
For most modern operating systems like Windows 7, 8.1, and 10, the driver for the CH340C chip will often install automatically once you connect the board to the internet. If it doesn’t, drivers are readily available online from the manufacturer’s or seller’s websites.
Q: Can I power this board from a battery?
Yes, you can power the board using a 6V-20V unregulated external power supply connected to the VIN pin (pin 30) or a regulated 5V source to the 5V pin. The power source with the highest voltage is automatically selected.
Q: What is included in the package?
The package typically includes the Nano V3.0 ATmega328P+CH340C development board with welded pins and a 30cm Micro USB to USB cable.
