Abstract
This utility model discloses a wireless communication circuit, including a pin header, a communication chip, and a level adjustment module. The serial port of the pin header includes a transmit pin and a receive pin. The level adjustment module includes a first level adjustment circuit and a second level adjustment circuit. The transmit pin is connected to the receive end of the communication chip through the first level adjustment circuit; the receive pin is connected to the receive end of the communication chip through the second level adjustment circuit. The pin header is connected to external circuits, such as the circuit boards of gateways and other electronic devices. The serial port of the pin header is connected to the external circuit. After passing through the level adjustment module, the level is reduced to the serial port level of the communication chip before connecting to the serial port of the communication chip; this prevents the communication chip from being damaged by a high level.
