安信可 RA-01 SX1278 LoRa 擴頻無線模組 / 433MHz無線串口/SPI接口/ 安信可原廠出貨 Ra-01

The Ra-01 LoRa module is made by Ai-Thinker company, the manufacturer of the ESP32S module, the module uses SX1278 IC, works on 433MHz frequency. It is a high quality made module. The dimension is very small, only 17 x 16 mm, with all the SX1278 pins breakout. The antenna is a spring antenna, well tested by experienced engineer.

The SX1287 transceivers feature the LoRaTM long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption. Using Semtech’s patented LoRaTM modulation technique SX1287  can achieve a sensitivity of over -148dBm using a low cost crystal and bill of materials. The high sensitivity combined with the integrated +20 dBm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness. LoRaTM also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity and energy consumption.
