[IC] : SX1278

[Frequency] : 410~441MHz

[Power] : 10~20dBm

[Distance] : 3.0km

[Interface] : UART

[Introduction] : E32-433T20S1 is a wireless transceiver module based on SX1278 of SEMTECH (it can be transmitter and receiver both). It adopts LoRa spread spectrum technology, with this technology the transmitting distance and diffraction of the module improved greatly compared with traditional FSK.

Mạch thu phát RF SPI Lora SX1278 433Mhz; sử dụng chip SX1278 của nhà sản xuất SEMTECH chuẩn giao tiếp LORA (Long Range) tiết kiệm năng lượng và có khoảng cách xa. Hiện nay LORA đang được dùng điển hình trong mạng IoT.
