Serial wireless data transmission module YL-2W

Chip solution: LoRaTM spread spectrum modulation technology Carrier frequency: 420-450MHz No application frequency band, other frequency bands can be customized Transmission power: Maximum transmission power+33dBm Communication distance: Effective in open areas up to 10-12 kilometers Product size: 99 * 96 * 24.4mm Communication interface: MAX485/MAX232/TTL Product introduction: YL_LoRa_2W is a high-performance, low-power, long-distance low-power RF wireless data transceiver with internal automatic spread spectrum calculation and preamble CRC error correction processing, without changing any user data and protocol. It adopts a half duplex transparent transmission mechanism to achieve wireless replacement function. The RF chip of the radio station is based on spread spectrum frequency hopping technology, which surpasses existing GFSK radio stations in terms of stability, anti-interference ability, and reception sensitivity. Configuring STM low-power high-speed processor has improved data processing capability and computing speed. Users can flexibly configure the working frequency, serial port rate, spreading factor, effective data ratio, and spreading bandwidth of the radio station according to their actual needs through the upper computer software configured by our company. The operation is simple and easy to use. The software and hardware of the radio station are designed according to industrial standards and have strong protective measures. Ensure stability in special environments
