pip install ch340_nrf

import ch340_nrf
import time

# Create a new instance of the ch340_nrf class
module = ch340_nrf.NRF("COM3")

# Get the system information
print(module.get_system_info())

# Send a message
module.send_message("Hello World!")

# Wait for a response
time.sleep(0.5)

# Print the response
print(module.get_message())

I made this library because there are no other libraries that allow you to use the ch340 nrf usb adapter with python. After reading the thread on the arduino forums here, I decided to make my own library. I hope this library helps you with your projects!
