1. Product Overview

1.1 Brief Introduction

E28-2G4M27S is a 2.4GHz small SMD module (pin spacing
1.27mm)designed by Chengdu Ebyte. With built-in PCB antenna, SPI
interface, it owns TX power of 500mW with power consumption.
The IC SX1280 from Semtech features multiple physical layers and
various modulating methods such as LoRa, FLRC and GFSK, the special
modulating methods and processing ways enable longer operating range
under LoRa and FLRC modulating methods, and the GFSK method covers
BLE protocol. The outstanding ultra-low power consumption and the DC-DC and Time-of-Flight on chip make the chip
much more capable for smart home, security system, tracking and locating, wireless distance measuring, wearable
electronics, smart bracelet and health management & etc.
E28-2G4M27S is a hardware platform without firmware, so users need to conduct secondary development.
