Usage Instructions

How to Use the pyBoard_clone in a Circuit

Powering the Board:
- Connect the board to a computer via the Micro-USB port for power and programming.
- Alternatively, supply power through the VIN pin (3.6V to 10V) and connect GND to the circuit ground.
Programming the Board:
- Install MicroPython on the board if not pre-installed.
- Use a MicroPython IDE (e.g., Thonny) or a terminal-based REPL to write and upload code.
- The board will appear as a USB mass storage device, allowing you to drag and drop Python scripts.
Connecting Peripherals:
- Use the GPIO pins to interface with sensors, actuators, and other modules.
- Ensure that the voltage levels of connected peripherals are compatible with the board's 3.3V logic.
Example Circuit:
- Connect an LED to pin D13 with a 220-ohm resistor in series.
- Use the following MicroPython code to blink the LED.

Example Code: Blinking an LED

from machine import Pin
from time import sleep

Configure pin D13 as an output pin

led = Pin('D13', Pin.OUT)

while True: led.value(1) # Turn the LED on sleep(1) # Wait for 1 second led.value(0) # Turn the LED off sleep(1) # Wait for 1 second

Important Considerations

Voltage Levels: Ensure that all connected peripherals operate at 3.3V logic levels. Use level shifters if necessary.
Power Supply: Avoid exceeding the input voltage range (3.6V to 10V) to prevent damage to the board.
Static Protection: Handle the board with care to avoid electrostatic discharge (ESD) damage.

Troubleshooting and FAQs

Common Issues and Solutions

Board Not Detected by Computer:
