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. The Module uses a 26MHz
±
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.
1.2 Main Features:
The measured actual communication distance can reach 2km;
The maximum transmission power is 17dBm (50mW);
Broadband design 400MHz-525MHz, supporting the global license-free ISM 433MHz band;
High receiving sensitivity and high receiving selectivity;
Optional FEC, and automatic channel noise level tracking;
Support multiple modulation modes (FSK / MSK / 4-FSK / GFSK / GMSK / ASK / AFSK / FM / PSK);
Support wireless wake-up;
Support DC 1.8 ~ 3.6V power supply, DC 3.3V-3.6V can guarantee the best performance;
Industrial grade standard design, support long-term use from -40 to +85 °C;
