LoRa1280 & LoRa1281 : 2.4GHz LoRa Modules Using SX1280 And SX1281 With ESD Protection
- LoRa1280 and LoRa1281 strictly uses lead-free process for production and testing, and meets RoHS and Reach standards.
- This LoRa module is designed based on the original sx1280 & sx1281 radio frequency chip of Semtech in the United States. It uses LoRa's modulation mode, which improves the short communication distance of ordinary 2.4GHz modules. The high penetration performance of the 2.4GHz frequency band combined with the LoRa modulation enables the module to have high receiving sensitivity and environmental anti-interference ability. The whole series of modules are widely used in applications requiring long-distance 2.4GHz transmission.

| 2 | DIO3 | Directly connected to the chip pin, configurable general-purpose IO (see the chip SX1280/1281 specification for details) |
| 3 | VCC | Connected to the positive pole of the power supply (1.8-3.7V) |
| 4 | GND | Connected to the negative pole |
| 5 | MISO | SPI data output pin |
| 6 | MOSI | SPI data input pin |
| 7 | SCK | SPI clock input pin |
| 8 | NSS | Module chip select pin |
| 9 | ANT | Connect with 50 ohm coaxial antenna |
| 10,11,12 | GND | Connected to the negative pole |
| 13 | NRESET | Chip reset trigger pin, active low |
| Note: For Lora1280 and Lora1281 modules, PIN 14 is GND | ||
| 14 | GND | Connected to the negative pole |
| Note: For Lora1280-TCXO module, PIN 14 is TCXOEN | ||
| 14 | TCXOEN | Turn on TCXO: 1. Turn TCXOEN pin to high level before reset SX1280; 2. Delay at least 3ms to wait for the TCXO startup; 3. During the use of the 1280 module, TCXOEN must keep in high level; Turn off TCXO (if the module needs to enter sleep mode): 1. Call the SetSleep() function to make the module enter the sleep mode; 2. Delay at least 1ms to wait for module sleep; 3. Turn TCXOEN pin to low level to turn off TCXO. |
| 15 | BUSY | Status indicator pin (see SX1280/1281 specification for details) |
| 16 | DIO1 | Directly connected to the chip pin, configurable general-purpose IO (see the chip SX1280/1281 specification for details) |
