Independent R&D based on imported SEMTECH chips
Cost-effective LoRa wireless UART module
*RSSI environmental monitoring
*Power failure protection
*Power multi-level adjustable
Working Frequency band:850.125~930.125MHZ
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
LoRa spread spectrum technology characteristics:anti-interference,
longer transmission distance,guarantee communication stability.
Global license- free ISM band 868/915MHZ
A wide frequency range to meet the needs of multiple applications
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.
RSSI signal strength indicator function
Good for various operation such as evaluating signal quality improving communication networks,and ranging.
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.
Equipped with high-quality components to ensure that each product has a better performance.
