Introduction

PNP3308 is an SPI-interface pure RF data transmission module based on the SI4438-C RF chip. It is an industrial-grade wireless data transmission product designed for indoor or outdoor environments with coverage up to 1 km (range may vary depending on environment).

SI4438-C is a high-performance wireless transceiver chip with a maximum output power of 100mW, operating in the 425MHz~525MHz frequency band with a default frequency of 490MHz.

This module is a high-performance, low-current 425MHz~525MHz transceiver module featuring a receive sensitivity of -124dBm, maximum output power of +20dBm, support for (G)FSK and OOK modulation, data rates from 100bps to 500Kbps, operating voltage of 1.8V~3.8V, shutdown current of 30nA, and standby current of 50nA.
