Introduction

The PNP7306 is an SPI-interface pure RF data transmission module based on the SX1278 RF chip. It is an industrial-grade wireless data transmission product designed for indoor or outdoor environments with a coverage range of 1~5 km (distance may vary depending on environment).

The SX1278 is a high-performance, low-power, long-range micro-power RF wireless data transceiver chip. It features built-in automatic spread spectrum computation and CRC error detection, operates transparently without altering any user data or protocols, and employs a half-duplex transparent transmission mechanism to achieve wireless replacement functionality.

The PNP7306 RF module developed based on this chip surpasses existing GFSK modules in terms of stability, anti-interference capability, and receiver sensitivity.

Users can flexibly configure module parameters — including operating frequency, serial port baud rate, spreading factor, effective data rate, and spreading bandwidth — via host computer software according to actual requirements, making operation simple and convenient.

Features

• LoRa spread spectrum modulation technology
• 434~498MHz license-free band
• No calibration required in production, 2.4~3.7V wide voltage range
