Independent R&D based on imported SEMTECH chips

Cost-effective LoRa wireless UART module

*Communication key

*RSSI environmental monitoring

*Power failure protection

*Power multi-level adjustable

Working Frequency band:850.125~930.125MHZ

Transmitting Power:22dBm

Use original imported chips

LLCC68 from SEMTECH

The E220 series is based on the original imported SEMTECH chip solution and professional R&D.

Compared with the SX1278/SX1276 solution ,

the transmission distance is longer,the speed is faster ,and the power consumption is lower.

Use new LoRa spread spectrum technology

Good for ultiple transmission methods

Fixed-point transmission,broadcast transmission,

channel monitoring communication methods according to needs are available.

WOR,effectively achieve low power consumption

Greatly reduce the power consumption of the receiving end suitable for battery-powerd applications.

E220 is equipped with efficient watchdog protection

Once an exception occurs,

the module will automatically restart and continue to work according to the current parameter.

Smaller size for easier integration

The E220 series adopts a highly integrated circuit design,

coupled with a reasonable PCB layout to greatly reduce product volume.
