Chengdu Ebyte Electronic Technology Co., Ltd. E10-433MD-SMA User ManualCopyright ©2012–2018,Chengdu Ebyte Electronic Technology Co.,Ltd. 21 Overview1.1 Brief introductionE10-433MD-SMA is DIP wireless module working at433MHz developed based on chip SI4463 from Silicon Labs.Due to the use of the imported Si4463 as the core of themodule, its stability has been well received by users, andcompatibility is not a concern. The module is aimed at smarthome, wireless meter reading, scientific research and medical,and medium and long distance wireless communicatio nequipment. Since RF performance and component selection are in accordance with industrial standards, and the producthas obtained FCC, CE, RoHs and other international authoritative certification reports, users do not need to worry aboutits performance. With its stable and reliable characteristics, it is favored by the majority of users. Compared with the oldproducts, it has made great progress in receiving current, receiving sensitivity, transmitting power, receiving rate range an danti-interference ability. High precision 26MHz crystal is used.Since the module is a pure RF transceiver module, you need to use the MCU driver or a dedicated SPI debug tool.1.2 Feature Communication distance tested is up to 2km Maximum transmission power of 100mW, software multi-level adjustable; Support the global license-free ISM 433MHz band; Support air date rate of 1.2kbps~1000kbps; Support multiple modulation methods, (G)FSK, 4(G)FSK, (G)MSK,OOK ; Support 64/128 byte Transceiver Data Register (FIFO); Support 2.5V~3.6V power supply, power supply over 3.3 V can guarantee the best performance; Industrial grade standard design, support -40 ~ 85 °C for working over a long time; SMA connector, good for connecting external antenna.1.3 Application Home security alarm and remote keyless entry; Smart home and industrial sensors ; Wireless alarm security system; Building automation solutions ; Wireless industrial-grade remote control; Health care products; Advanced Meter Reading Architecture(AMI); Automotive industry applications .
