EBTYE OEM/ODM E32-433T20DC SX1278 433Mhz UART Wireless lora module
[ Model ]:E32-433T20DC1B
[ Interface ]:UART
[ Power ]:20dBm
[ Distance ]:3000m
[ RF connector]:SMA-K
[ Frequency ]:433MHz (410-441)
[ Feature ]: E32-433T20DC1B is a wireless transceiver module based on SX1278 from SEMTECH(can be transmitter and receiver both). It adopts LoRa spread spectrum technology, with this technology the transmitting distance and penetration ability of the module improved more than 1 times compared with traditional FSK.The module features FEC (forward error correction) algorithm, which ensure it's good anti-interference ability. E32-433T20DC can be compatible with other E32 modules.
NOTE: The product has been upgraded, the new version E32-433T20DC1B is fully compatible with the old version E32-433T20DC, and the performance is better.
