1. Product Introduction
- Key Features
Ra-05
- Ra-05 is a 2.4GHz RF transceiver module developed by Shenzhen Ai-Thinker Co., Ltd. Equipped with Semtech's SX1281 RF chip as the core processor, this module supports multiple modulation methods such as LoRa, FLRC, and GFSK, and is compatible with Bluetooth protocols. It is a pure RF transceiver module that requires an MCU for driving or a dedicated SPI debugging tool.
- LoRa's direct-sequence spread spectrum technology enables longer communication distances, with advantages of a wider power spectrum and strong anti-interference capabilities. The module features a hardware FEC (Forward Error Correction) algorithm, which offers high coding efficiency and robust error correction. In the event of burst interference, it can actively correct corrupted data packets, significantly enhancing reliability and transmission range.
- The module offers high transmit power and receive sensitivity, with excellent performance in spectral characteristics, harmonic spurs, and channel crosstalk. Additionally, it features a compact size and strong package compatibility.
