Ebyte SPI RF Module Selection Guide

Ebyte SPI RF modules are embedded wireless transceivers designed for IoT and industrial control systems, based on the Serial Peripheral Interface (SPI) protocol. They connect directly to the host MCU via the SPI bus for full-duplex high-speed data transmission, and integrate RF chip, matching circuit, antenna interface and power management unit on board.

Compared with UART modules, SPI RF modules offer lower latency, higher throughput and simpler hardware architecture. The product portfolio covers 2.4GHz ISM band and Sub-1GHz license-free bands, supporting LoRa, (G)FSK, OOK and proprietary modulation schemes. They are ideal for sensor networks, smart metering, industrial control and gateway designs.

How to Select SPI Module?

* Max LOS range is measured in open environment with matched antenna. Actual performance varies with obstacles, interference and antenna gain.

5-Point Quick Selection Guide

  1. Choose frequency band by deployment scenario. Select 2.4GHz series (E01, E28) for global market compatibility and higher data rate; select Sub-1GHz series for outdoor long-range deployment, wall penetration and industrial interference environments.
  2. Select modulation by communication requirement. Choose LoRa spread spectrum series (E22, E28, E106) for long-distance and high anti-interference links; choose FSK/GFSK series (E01, E07, E30) for applications requiring higher data throughput.
  3. Match output power to your link budget. Use E28 or E29 series (up to 16km) for ultra-long-range wireless links; use E22/E32 series (3–8km) for standard industrial LoRa nodes; use E01/E07 series for short-range on-board integration.
  4. Evaluate supply chain and cost target. Choose Semtech/TI chip based series (E07, E22, E28, E106) for mature software ecosystem and global certification; choose domestic chip solutions (E29, E48) for cost-sensitive projects and secure supply.
  5. Optimize for hardware integration effort. All SPI modules use standard SPI interface for direct connection to host MCUs. Select the series with matching package size, power consumption and peripheral features according to your PCB layout and firmware architecture.
