XL105-232AP2 is a UART interface half-duplex wireless transmission module. It is equipped with an antenna, has a small size, and is suitable for wireless communication connections within 100 meters. The module works in the 2400-2483MHz public frequency band and supports the setting of parameters such as serial port speed, working channel, and product ID.
The XL105-232AP2 is a low‑power, half‑duplex wireless module with a UART interface, designed for short‑range communication up to 200 m. It operates in the 2400‑2483 MHz band, supports configurable serial parameters and provides a compact 31 mm × 17 mm form factor.
The manual provides detailed specifications, pin assignments, power supply guidelines, configuration procedures, and a troubleshooting guide for common issues such as signal loss, power problems, and mismatched communication settings. This manual is written in Chinese.

Use the SET pin to enter programming mode, send the new parameters via the serial interface, and the module will store them internally for future use.
The module’s transmit current should not exceed 60 mA; typical transmit current is 70 mA as specified, but the design recommends keeping it under 60 mA.
