This article covers Eoutegn 2.4G SX1302 Lora Wan 半二重ワイヤレス モデム E870 27dbm 距離 3KM PA+ リモート アップグレード NTP DC 8.
Overview
The Eoutegn 2.4G SX1302 Lora Wan Half-Duplex Wireless Modem E870 is a specialized LoRaWAN modem designed for long-range IoT communications. With a powerful 27dBm output, it achieves a line-of-sight range of up to 3 kilometers. The built-in PA+ (power amplifier) enhances signal strength for reliable long-distance links. It supports NTP for precise time synchronization and remote firmware upgrades, simplifying post-installation maintenance. The modem operates over a wide DC 8–28V input range and supports both 868MHz and 2.4GHz frequency bands, offering flexibility for global deployments. ## Specifications | Item | Specification | |------|---------------| | Model Number | E870-L47012-S | | Chipset | SX1302 | | Protocol | LoRaWAN | | Duplex | Half-duplex | | Output Power | 27dBm | | Range | Up to 3 km (LOS) | | Frequency Bands | 868MHz / 2.4GHz | | Power Input | DC 8V–28V | | PA+ | Built-in | | NTP | Supported | | Remote Upgrade | Supported |
Connectivity & Compatibility
This modem uses the LoRaWAN protocol and is compatible with any LoRaWAN gateway and network server. The 868MHz band is suitable for European regions, while the 2.4GHz band is a global ISM band, allowing frequency selection based on local regulations. The wide DC input range (8V to 28V) makes it easy to power from solar panels, batteries, or industrial supplies. Half-duplex communication means transmit and receive are time-shared; plan your application data flow accordingly.
Product Info
The Eoutegn LoRaWAN modem is available on , with an approximate price of ¥12,763 (tax included). It is positioned as an entry-to-mid-range industrial IoT modem. The package includes the modem unit only; antenna and power cables must be purchased separately. Warranty terms follow the seller's policy. Compared to similar SX1302-based modems, this model offers added value with PA+ amplification and NTP support.
Best Use Cases
This modem is ideal for agricultural and environmental monitoring, smart city sensor networks, and remote data collection where long range and low power are critical. It suits users who need time synchronization (NTP) and remote firmware updates for deployed devices. Its high output power and flexible power supply make it particularly useful for outdoor installations with unstable power sources or for projects that require covering large areas with distributed sensors.
