1. 서론
The EBYTE E32 Series LoRa Modules are advanced wireless serial port modules (UART) designed for long-distance, low-power communication. Based on SEMTECH's SX1276 RF chip, these modules leverage LoRa spread spectrum technology to offer superior anti-interference capabilities and extended transmission distances. Available in various frequencies (433MHz, 868MHz, 915MHz) and power outputs (20dBm, 30dBm, 33dBm, 37dBm), they come in both SMD (Surface Mount Device) and DIP (Dual In-line Package) form factors with different antenna interfaces (Stamp Hole, SMA-K, IPEX).
These modules are suitable for a wide range of IoT application scenarios, including smart agriculture, wireless remote control, industrial automation, and smart wearables.

2.2 물리적 연결
Connect the module to your microcontroller or development board using the UART interface. Ensure correct wiring for VCC, GND, TXD, RXD, AUX, M0, and M1 pins. Refer to the specific module's datasheet for detailed pinout diagrams.
2.3 안테나 연결
Attach the appropriate antenna to the module's SMA-K or IPEX/stamp hole interface. Ensure a secure connection for optimal performance.

3. Operating Modes and Transmission
3.1 작업 모드
The E32 series modules support four distinct working modes, configurable via software, to optimize power consumption and communication behavior:
- 전송 모드: The most commonly used mode, enabling transparent data transmission.
- 웨이크업 모드: A low-power consumption mode where the transmitter can be woken up by an 'air wake-up' signal, automatically adding a wake-up code.
- 절전 모드: A receiver-only mode with low power consumption (wake on air). In this mode, the module cannot transmit data.
- 깊은 절전 모드: The lowest power consumption mode, where the overall power consumption is typically only 2uA, significantly extending battery life.
3.2 Transmission Methods
Multiple transmission methods can be implemented through software configuration, offering flexibility for various communication needs:
- 지점 간: Direct communication between two modules.
- Point-to-Many (Broadcast): One module transmits data to multiple receiving modules.
- 모니터 모드: Modules can listen to communications on a specific channel.
3.3 LoRa Spread Spectrum Communication
The integrated SX1276 chip supports LoRa Direct Sequence Spread Spectrum technology, which provides:
- Longer communication distance.
- Stronger anti-interference ability.
- Enhanced confidentiality.
