General Description

JB24M is a low cost, low power and high performance of 2.4GHz ISM band wireless digital data transceiver module, which supports package handling hardware including preamBluetooth Smart, sync word FEC, CRC data whitening and Manchester coding. That makes JB24M easy to be used together with a low cost and low speed micro-controller (MCU).
JB24M can widely be applied to data transmitting, signal control and those specified as preferred components in remote control garage, roller curtain, door locks, remote sensing, telemetry, industrial control and wireless security alarm industry.
