Ra-01 LoRa Module

The Ra-01 LoRa module, manufactured by Ai-Thinker (the same company behind the ESP32S module), utilizes the SX1278 IC and operates at a 433MHz frequency. This high-quality, compact module measures just 17 x 16 mm and features all the SX1278 pins exposed. It is equipped with a well-tested spring antenna.

The SX1278 transceiver includes the LoRa™ long-range modem, which offers ultra-long range spread spectrum communication, high interference immunity, and low current consumption.
