Frequently Asked Questions (FAQs)

• Q: Can this shield program blank ATmega328P chips?
  A: Yes, the 28P locking socket is specifically designed for programming new ATmega328P chips.
• Q: Does it support Arduino Nano?
  A: No, this module does not support direct Nano programming. Only UNO R3, Mega2560, and Pro Mini (5V 16M) boards are compatible.
• Q: Do I need additional drivers?
  A: FT232RL and CH340G may require drivers depending on your operating system.
• Q: Does the buzzer always beep twice?
  A: Only successful fuse writing and bootloader burning produce two beeps. Fewer or no beeps indicate failure.
• Q: Is this suitable for beginners?
  A: Yes, the module is very beginner-friendly and recommended by Bigyan Project for learning AVR programming.
