In complex application scenarios such as industrial IoT, smart cities, and energy monitoring, stable, reliable, and long-range data transmission is critical to system success. Leveraging its profound technical expertise, EBYTE launches the flagship product of its industrial-grade wireless data radio series—the E90-DTU(400SL42).

The Serial Peripheral Interface (SPI) is a synchronous, full-duplex serial communication protocol designed for short-distance data exchange between microcontrollers (MCUs) and peripheral devices such as sensors, displays, and memory chips.

ZigBee is widely used in smart home, industrial IoT, and smart lighting due to its low-power mesh networking. However, multi-node performance varies significantly across vendors.

SPI (Serial Peripheral Interface) is a high - speed, full - duplex, synchronous serial peripheral interface specification widely used in short - distance communication in embedded systems. This article will detail the technical features of the SPI interface and focus on the advantages of the EBYTE SPI module and its performance in practical applications.

In today's Internet of Things (IoT) and embedded systems fields, the Serial Peripheral Interface (SPI) module, as a high - speed, full - duplex, synchronous serial peripheral interface specification, is playing an increasingly important role. With its efficient data transmission capabilities and flexible configuration options, the SPI module has become the preferred interface for many wireless communication devices.

The E01C - 2G4M11S is a small - sized 2.4 GHz SMD wireless module independently developed by Ebyte with the Ci24R1 chip . It comes with a built - in PCB antenna and uses an industrial - grade high - precision 16 MHz crystal oscillator. Since the E01C - 2G4M11S wireless module is a pure RF transceiver module, it requires an MCU for driving or a dedicated SPI debugging tool.
