FSK (Frequency-shift keying) is two way high speed transmission modulation, also known as digital frequency modulation, narrow-band communication, always uses high-sensitivity RF chip.
FSK Wireless Transceiver Module are RF modules with FSK modulation, can be used as RF transmitter and RF receiver with a same RF module, 433/868/915MHz, 2.4G available ...
Advanteges:
1. Narrowband communication, using high sensitivity RF chip designHigh communication speed and strong anti-interference ability.
2. All kinds of data transmission modes, low power consumption and WoR (wake-on-radio) function can be realized by software design.
3. Anti-noise and anti-attenuation performance is good, and it is widely used in medium and low speed data transmission
