1.Overview

1.1 Introduction

Designed by Ebyte, E31-400M17S is a micro-size(pin pitch:1.27mm) long range RF transceiving
module with 400MHz central frequency(Range:425-450.5MHz); Based on AXSEM's AX5243 RF chip
—a narrow-band multi-channel single-chip, the module has multiple modulation methods such as FSK /
MSK / 4-FSK / GFSK.The module antenna interface is IPEX stamp hole.
± 1ppm industrial grade high precision low temperature drift active crystal oscillator to ensure the accuracy of wireless frequency,
industrial performance and its stability.
The module is a pure RF transceiving hardware which requires MCU drivers or special SPI tool to configure before being put in
work.
