What are the front-end LoRa modules using SX1276
By sdga:NiceRF Wireless Technology Co., Ltd
SX1276 is designed by Semtech with LoRa modulation, which has high sensitivity, big packet FiFo, low power consumption, and strong anti-interference.
NiceRF has below front-end LoRa modules which using SX1276:
LoRa1276，LoRa1276-C1，LoRa1276F30
SX1276 LoRa module
Introduction of front-end LoRa modules using SX1276:
LoRa1276 and LoRa1276-C1 is 100mW output, built-in anti-static protection, small size. They are widely used in wireless meter reading, remote industrial control and other applications.
LoRa1276F30 is 1W output. It is used in longer range coverage.
How to choose these three SX1276 LoRa modules?
Same Features:
1. Working temperature range:-40~85℃
2. RF data rate: 0.018-37.5 Kbps@LoRa
3. TX/RX FIFO: 256 bytes, CRC and frequency hopping
4. 127 level for RSSI value
5. customized at 137-1020MHz
