FAQ Section
1. What is the core advantage of 170MHz frequency compared with common 433MHz SI4463 modules?
170MHz lower frequency features longer radio wavelength, stronger penetration and diffraction performance through thick walls, soil, rocks and metal obstacles. It achieves more stable communication in mountain, underground mining and multi-story building scenarios, while 433MHz modules suffer severe signal attenuation under dense barrier environments.
2. Can the transmit power of E30-170T27D be adjusted via software configuration?
Yes, users can switch transmit power between 18dBm to 27dBm through UART AT command configuration. Low power mode reduces power consumption for short-distance indoor projects, while maximum 27dBm power unlocks full 5km open-air transmission range for long-distance outdoor monitoring.
3. What power supply voltage range does this DIP RF module support, and what voltage delivers optimal performance?
The module supports input voltage from 3.3V to 5.2V DC, 5V power supply delivers the most stable RF transmit performance and maximum 27dBm output power. It can work normally with 3.3V lithium battery power supply for low-power portable sensor nodes, with slightly reduced transmit range.
4. Does E30-170T27D support OEM bulk customization for overseas industrial equipment manufacturers?
Ebyte provides full OEM and ODM customization service for E30-170T27D. Bulk buyers need to confirm test sample firmware version with sales before mass order, the standard DIP 24*43mm layout is compatible with most custom control PCB boards, and Ebyte can offer pre-programmed firmware matching client IoT sensor protocols.
5. What anti-interference and error correction mechanisms does the SI4463 chip inside this module integrate?
The built-in SI4463 RF chip integrates FEC forward error correction algorithm, automatic frequency control and automatic gain control circuits. It can actively correct corrupted data packets under industrial electromagnetic interference, improving transmission stability and reducing packet loss rate in factory, power station and mining sites with heavy RF noise.
