Lubeby Smart SA818S New Generation VHF 134~174MHz/UHF 400-480MHz 1W 30dBm Analogue Walkie Talkie Module (UHF :400~480 MHz X 2 PCS)
- SA818S is a cost-effective integrated professional walkie-talkie module, built-in high-speed microcontroller, high-performance RF transceiver chip and RF power amplifier, and provides a standard serial port to communicate with the module
- so that the relevant parameters of the module and the transceiver can be set quickly and easily. Function to control.
- Users only need to connect an audio amplifier, microphone, and speaker to this module to work as a small walkie-talkie.
- The simplified interface and ultra-small size enable this module to be widely used, and it can also be easily and quickly embedded in various handheld devices to improve the overall performance of the terminal product.
- SA818S walkie talkie module adds an LNA circuit on the basis of SA818, and the sensitivity is increased by 4dBm. For the entire frequency range of 400-470MHz, the power output fluctuation is less than 1dB, and the low power can achieve an error of 27dBm+/-1dBm from 400-470MHz. Note: The softw
