Product Description
Product description
YL-900IL is a high performance, low power consumption, remote micro power RF wireless data transceiver module, the internal automatic spread spectrum calculation and lead CRC error correction processing, without changing the user\'s any data and protocol, the use of half duplex and transparent transmission mechanism to achieve wireless instead of function. The module of RF chip based on spread spectrum frequency hopping technology, in the stability, anti-interference ability and receiving sensitivity are beyond the existing GFSK module. Configuration STM low power high speed processor, data processing ability, computing speed are improved.
The user can configure the upper computer software according to the actual needs of the flexible configuration module of the operating frequency, serial rate, spreading factor, effective data ratio and spread spectrum bandwidth and other parameters, the operation is simple, easy to use.
Product features
Spread spectrum modulation technology based on LoRa.
Half duplex communication, serial data transparent transmission.
420~450MHz free application band, other bands can be customized.
Production free debugging, 5-15V wide voltage range.
