FLY-Pi Usage Precautions

Read Before Operating

Before any wiring operations, please ensure the printer is turned off and disconnected from the power supply. When flashing firmware, also follow the corresponding guide.

1. Power Requirements​

  • Type-C Power Supply (Recommended for First Boot): Use a power adapter rated at 5V/2A or higher. Some computer USB ports may not provide sufficient power, which could cause the system's initial automatic expansion to fail.
  • DC Terminal Power Supply: Supports DC 12V-24V input.
  • For detailed power supply instructions, please refer to Host Power Supply.

2. Storage Configuration​

Important

The FLY-Pi does not come with any storage device from the factory (i.e., it does not include the M2WE Module or a Micro SD Card). You must configure at least one of the following storage media for the device to operate properly:

  • Option One (Recommended): Purchase the FLY custom M2WE Module for faster system response and higher reliability.
  • Option Two: Provide your own Micro SD (TF) Card with a capacity between 16GB and 128GB.

3. Important Warning​

Interface Conflict Warning

It is prohibited to use the TFT screen, SPI accelerometer interface, and RRF expansion interface simultaneously!

  • Reason for conflict: The TFT screen interface (FPC-TFT), SPI accelerometer interface (ZH1.5-6P), and RRF expansion interface share the same set of SPI resources on the hardware.
  • Consequence: If connected simultaneously, it will cause abnormal screen display and severely erroneous accelerometer data.
  • Solution: Please ensure that only one of these devices is connected and used at a time.
