Nano V3Atmega328P MCU Core Board Welding Development Board Improved Version Module For Arduino

 

High-current devices must be powered separately, otherwise the board may burn out!

The 3.3V output on the board has a power supply capacity close to zero. This pin is connected to the CH340’s V3 pin. Modules like the NRF24L01 (which will not communicate without the board’s 3V3 power supply), the ESP8266, and OLED are best powered using an expansion board or a separate 3.3V power supply. (Note!)

Some computers’ USB 3.0 ports can overheat the power supply chip due to current draw. Please use a USB 2.0 port for power and program downloads.

Use a USB-A to Type-C cable for downloads! Most third-party mobile phone charging cables don’t have data transfer capabilities!

The board does not have a USB 3.0 protocol chip, so a Type-C to Type-C cable will not work. Please note!

If you are unable to download the program, please first confirm that the driver is the latest version of the CH340 driver. If you have installed an older version, we recommend uninstalling it and then installing the latest driver from the official CH340 website.

The board uses a Type-C port, making it easy to plug and unplug for debugging.

The chip is original and can be used directly with software such as Arduino, Mind+ (not supported by the Nano 168P series), Linkboy (not supported by the Nano 168P series), and Mixly, without any software configuration modifications.

The 168P board uses a 32-pin chip with pins A6 and A7.

The 328P board uses a 28-pin chip, similar to the ATmega-328PPU, without pins A6 and A7. Otherwise, the chip is identical.

Many people have asked what the difference is between the 168P and 328P boards.

Here’s the answer:

The 168P board uses the Atmega168PA chip.

The 328P board uses the Atmega328P chip.
