Product Description

• Developed by the company Ai-Thinker, manufacturer of the ESP32S, this Ra-01 LoRa (long range radio) module will take your IoT projects remotely with communication over a long range extended spectrum.
• This form of wireless communication increases bandwidth, increases resistance to interference, minimizes current consumption, and increases security.
• This module uses an SX1278 integrated circuit and operates on a frequency of 433 MHz. Frequency hopping – which gives you the perfect balance between transmitting quality signals – will cover a frequency range from 420 to 450 MHz.
• This long-range wireless capability is packaged in a small case (17 x 16mm) and delivered by a spring-loaded antenna.
• With the LoRa Ra-01, you won’t have to compromise on range, interference immunity or power consumption.
• The technology behind this IC means it’s perfect for projects that need reach and power.
