LT8920 2.4Ghz RF 트랜시버 모듈 -200미터
(LT8920 2.4Ghz RF Transceiver Module)
개요
- 본 제품은 LT8920 2.4Ghz RF 트랜시버 모듈 -200미터입니다.
- 대략 200미터의 통신이 가능한 2.4Ghz 무선 트랜시버 LT8920 칩을 탑재하고 있는 제품으로 무선으로 데이터를 주고 받을 수 있습니다.
- 3.3V 시스템과 사용이 가능하며, 2.54mm 피치의 핀헤더를 가지고 있습니다.
- 통신 거리는 주위 RF 환경에 따라 영향을 받을 수 있습니다.
특징
- Working voltage: 2.2- 3.6V
- Working temperature:-40 - +85°C
- Emission current: 15-24ma
- Receiving current: 18mA
- Sleep current: 6uA
-
Pin interface:
- PKT: Transmit/receive status support bit
- RST: When RST is low, the chip will be turned off, current <1uA, and the value of the digital part will also be lost. If you want to keep the value of the digital register, you can enter sleep mode. When RST is high, the chip will be turned on and the register will return to the reset value.

Instructions for use:The two STM8 system classes burn the same program. After power-on, they start to send and receive each other. When receiving the other party's data, the TSET indicator on the system board will be on constantly, otherwise it will flash.The maximum communication distance is 200 meters in an open and non-electromagnetic interference environment.
