Electricity, when the power supply is working, it consumes approximately.
High sensitivity. Using frequency stabilization, the frequency is accurate and stable.
The pin control module works and saves power
Used for various frequency points, easy to debug and short delivery cycle.
Direct interface to the chip, easy to implement.
Good consistency and small size.
High cost performance, the transmission rate can reach up to
Ordering information

Notes
.The antenna has a great influence on the receiving effect of the module. It is best to connect a /wavelength single oscillator Antenna
. The position of the antenna also affects the reception effect of the module. The antenna can be soldered directly to the port, or it can be connected through the pin system and then connected to the antenna. When installing, the antenna should be stretched as straight as possible and away from the shield. High voltage and interference sources
. Users only need to add a simple data decoding circuit to easily develop wireless products
. The driving current of the data output pin is weak. If it is directly When driving a microcontroller, the input/output port of the microcontroller must not be connected to a pull-up or pull-down resistor, and the pull-up or pull-down resistor inside the microcontroller must also be set to a disabled state.
