LoRa128X-T : SX1280/SX1281 2.4GHz FCC ID & CE-RED Certified TCXO Ranging Module

2.4 GHz transmitter and receiver module is designed based on the originalSX1280/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. The whole series of modules use a 10ppm industrial-grade crystal oscillator, and theLoRa1280/LoRa1281-TCXO module is also specially equipped with a higher-precision industrial-grade 0.5ppm TCXO temperature-compensated crystal oscillator, which guarantees stable frequency output under harsh environments such as high and low temperature. It also has the "time of flight" function, which can realize RF ranging applications.
LoRa1280-T strictly uses lead-free process for production and testing, and meets RoHS and Reach standards.
LoRa1280-T has obtained CE and FCC certification.

Features of 2.4 GHz transmitter and receiver LoRa1280-TCXO

LORA

Pin NO	Pin name	Description
1	DIO2	Directly connected to the chip pin, configurable general-purpose IO (see the chip SX1280/1281 specification for details)
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)）
