RF Sub-1GHz Module

HOWSEEN RF Sub-1GHz modules use a high-performance RF transceiver chip supporting GFSK/FSK/OOK modulation. With high receive sensitivity and a maximum +20dBm transmit power, they achieve long-range and low-power wireless data transmission. Featuring strong penetration, excellent anti-interference performance and ultra-low sleep power consumption, they are suitable for a wide range of long-distance wireless communication applications.
