Product Description
[ Model ]:E32-TTL-500
[ Interface ]:UART
[ Power ]:27dBm
[ Distance ]:5000m
[ RF connector]:SMA-K
[ Frequency ]:433MHz (410-441)
[ Feature ]: E32-TTL-500 is a 500mW wireless transceiver module. It operates at 410-441MHZ, based on SX1278 from SEMTECH, provides an easy way to use. It adopts LoRa spread spectrum technology, with this technology the module can transmit much longer distance than similar products under the same power with better anti-interference performance.E32-TTL-500 can be compatible with other E32 modules.
