• Sensor data acquisition and processing
• Wearable electronics
• Educational and prototyping projects

The Mini v6.7 is equipped with the following technical features:

The Mini v6.7 features a total of 20 pins, including power, digital, and analog pins. Below is the pin configuration:

1. Powering the Board:

   • Connect the VIN pin to an external power source (5V - 12V) or use the Micro-USB port for power and programming.
   • Ensure the GND pin is connected to the ground of your circuit.

2. Connecting I/O Devices:

   • Use the digital pins (D0-D13) for controlling LEDs, relays, or other digital devices.
   • Use the analog pins (A0-A5) for reading sensor data or other analog signals.

3. Programming the Board:

   • Connect the Mini v6.7 to your computer via the Micro-USB cable.
   • Use a compatible IDE (e.g., Arduino IDE, PlatformIO) to write and upload code.

4. Communication Interfaces:

   • Use UART (TX/RX) for serial communication with other devices.
   • Use I2C (SCL/SDA) or SPI (MOSI/MISO/SCK) for interfacing with sensors, displays, or other peripherals.

• Ensure the input voltage does not exceed the specified range (5V - 12V) to avoid damaging the board.
• Use appropriate pull-up resistors for I2C communication if required by your peripherals.
• Avoid drawing more current than the board's maximum output capacity (3.3V pin).

Below is an example of how to use the Mini v6.7 to blink an LED connected to pin D13:

// This example demonstrates how to blink an LED connected to pin D13
// on the Mini v6.7 microcontroller board.

void setup() {
  pinMode(13, OUTPUT); // Set pin D13 as an output pin
}

void loop() {
  digitalWrite(13, HIGH); // Turn the LED on
  delay(1000);            // Wait for 1 second
  digitalWrite(13, LOW);  // Turn the LED off
  delay(1000);            // Wait for 1 second
}

1. The board is not powering on:

   • Ensure the power source is within the specified voltage range (5V - 12V).
   • Check the Micro-USB cable and connection.

2. Unable to upload code:

   • Verify that the correct board and port are selected in the IDE.
   • Ensure the necessary drivers for the Mini v6.7 are installed on your computer.

3. Wi-Fi or Bluetooth not working:

   • Check the connectivity settings in your code.
   • Ensure the board is within range of the Wi-Fi network or Bluetooth device.
