315/433 RF 315 433 MHz RX TX Transmitter receiver Module

This is an FS1000A 433mHz Tx RF Radio Module. This RF module comprises an RF Transmitter and an RF Receiver. The transmitter-receiver (Tx/Rx) pair operates at a frequency of 433 MHz. An RF transmitter receives serial data and transmits it wirelessly through RF through its antenna connected at pin4.

The transmission occurs at the rate of 1Kbps – 10Kbps. The transmitted data is received by an RF receiver operating at the same frequency as that of the transmitter.

This low-cost RF transmitter can be used to transmit signals up to 100 meters (the antenna design, working environment, and supply voltage will seriously impact the effective distance). This wireless module is good for a short distance, battery power device development. RF 433 MHz is the operating frequency for the transmitter and receiver pair.

Features Of FS1000A RF433 Transmitter and Receiver Wireless Module:

• Wide input supply (2.5 V to 12V)
• Easy to integrate (V+, GND, and Data)
• The device in deep sleep mode when the Data pin is grounded
• Very small dimension.

Transmitter :

• Working voltage: 3V – 12V for max. power use 12V
• Working current: max Less than 40mA max, and min 9mA
• Resonance mode: (SAW)
• Modulation mode: ASK
• Working frequency: Eve 315MHz Or 433MHz
• Transmission power: 25mW (315MHz at 12V)
