ITEM NAME:E32-868T20D UART SX1276 Long Range rf Receiver Wireless rf Module New Description: A SEMTECH based SX1276 wireless transparent transmission module (transceiver integrated). Using advanced LoRa spread technology, the transmission distance and penetration ability are more than doubled compared with the traditional FSK. At the same time, using the FEC forward error correction algorithm, it can actively correct the interfered data packets and make the communication distance farther. Strong anti-interference ability. With air wake up function (ultra low power). Specification: Material: circuit board + copper Size: 49x21x13 mm / 1.92x0.82x0.51 inch Package Includes: 1 piece module.A SEMTECH based SX1276 wireless transparent transmission module (transceiver integrated).
