Only the Flywire version of Xiao Zhi is compatible—please note that only the rotary switch and TP4056 module are suitable for this configuration (for larger‑volume models). The charging module for the mini model is a 5V charging module sourced from Taobao, while the rotary switch model is SS12F15VG5. The mini‑size enclosure will be made available in a later release.                                   Please pay close attention! Attention! Attention! All enclosures are designed exclusively for development boards without header pins. The Guoyun development board uses M2‑size mounting screws, whereas the 44‑pin Espressif development board can be securely mounted using hot melt adhesive instead of screws.
