1. Preparations​

Hardware Checklist:

  • Tool Board: Fly-SHT36-V3
  • Host:
    Host Compatibility Note
    • Recommended Models: Fly-PI-V3, Raspberry Pi 4/5, and other standard hosts.
    • Unsupported Models: Redmi phones, WiFi sticks, set-top boxes, and various non-standard modified hosts.
    • Important Note: Using modified hosts may lead to system instability, functional abnormalities, or inability to operate normally.
  • Data Cable: One Type-C data cable.
  • Connection Method (Choose One):
    • CAN Connection: Requires a UTOC module or a mainboard flashed with USB-to-CAN bridge firmware.
    • RS232 Connection: Requires a UTOR module or a mainboard with native RS232 support (e.g., D8, D8-PRO, C8P).
  • Power Supply: 12V‑24V power adapter (ensure voltage is within range).
  • Computer: Windows PC (or another computer capable of using SSH tools).

2. User Guide & Important Notes​

Core Principle: Most issues are caused by configuration, connection, or power supply inconsistencies. Prioritize troubleshooting in the following order:

  1. Connection & Configuration: Ensure the DIP switch setting, firmware type, and the connection method in Klipper's [mcu SHT36] are all consistent (all CAN or all RS232).
  2. Power & Wiring: Confirm the supply voltage is correct and all cables are securely connected.
  3. Status Indicators: After powering on, check if the power and status LEDs are normal.
