Sample Code – WS2812 NeoPixel LED Control

This board is fully compatible with the Adafruit NeoPixel library. Here's a quick example to cycle through RGB colors on 3 WS2812 LEDs connected to pin 13:

#include <Adafruit_NeoPixel.h>
#define PIN 13
#define NUMPIXELS 3
Adafruit_NeoPixel strip = Adafruit_NeoPixel(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

void setup() {
  strip.begin();
  strip.show();
}
void loop() {
  setBrightness(10);
  setColor(255, 0, 0); delay(1000);
  setColor(0, 255, 0); delay(1000);
  setColor(0, 0, 255); delay(1000);
  setColor(255, 255, 255); delay(1000);
}
void setColor(int red, int green, int blue) {
  for (int i = 0; i < strip.numPixels(); i++) {
    strip.setPixelColor(i, strip.Color(red, green, blue));
  }
  strip.show();
}
void setBrightness(int brightness) {
  strip.setBrightness(brightness);
}

Frequently Asked Questions

Q: Is this ATmega328P Type-C board compatible with the Arduino IDE?

A: Yes! The Nano Mini ATmega328P board is fully compatible with the Arduino IDE. Simply select "Arduino Nano" as your board and choose the appropriate processor (ATmega328P). The CH340 USB-to-serial chip handles the communication — you may need to install the CH340 driver on your computer if it isn't already present.

Q: Do I need to install any drivers for the CH340 chip?

A: Most modern operating systems (Windows 10/11, macOS, Linux) will automatically detect the CH340 chip. If your computer doesn't recognize the board, simply download and install the free CH340 driver from the manufacturer's website. Once installed, the board will appear as a COM/serial port in the Arduino IDE.

Q: What is the advantage of the Type-C USB connector over Micro-USB?

A: The USB Type-C connector is reversible, meaning you can plug it in either way without checking orientation. It also supports more robust connection cycles and is the modern standard across most new devices — making it a convenient upgrade over older Micro-USB nano boards.

Q: Can I use this board for WS2812 NeoPixel or LED strip projects?

A: Absolutely. The ATmega328P is well-suited for controlling WS2812/NeoPixel LEDs via the Adafruit NeoPixel library. A sample sketch is included in the product description above to help you get started quickly.

Q: Is this board available in multi-pack quantities?

A: Yes! You can select from 1pc, 5pcs, 10pcs, or 20pcs options — perfect whether you're experimenting with a single project or stocking up for a classroom, lab, or production build.
