Ra-01 LoRa Module 410-525 MHz (Chinese Version)

Details

Compact LoRa radio module for long-range, low-power links such as sensors, meter reading and remote control. It connects to your MCU over SPI. This is the Chinese version: it is marked Ra-01 but does not carry the Ai-Thinker name or logo. The first photo shows the actual module; the second is a reference image of the Ai-Thinker Ra-01. Specifications and the datasheet link are from the Ai-Thinker Ra-01, so check them against your own design. Antenna is not included. Never transmit without an antenna connected. Use this module within the radio rules that apply in your area.
