LoRa1280F27-TCXO : SX1280 2.4GHz Industrial-Grade RF Module

LoRa1280F27-TCXO : SX1280 2.4GHz Industrial-Grade RF Module

This series of modules are designed based on the original sx1280 RF chip from Semtech,and the matching of the PA circuit makes the output power of the module up to 500mW(+27dBm).In addition, the LoRa1280F27-TCXO module is also equipped with an industrial-grade high-precision TCXO temperature-compensated crystal oscillator, which guarantees stable frequency output under harsh environments such as high and low temperature.
The 2.4GHz RF Module LoRa1280F27-TCXO strictly uses lead-free process for production and testing, and meets RoHS and Reach standards.

Pin NO	Pin name	I/O	Level standard	Description
1	VCC	-	2.0-5.5v	Connected to the positive pole of the power supply
Note: In Lora1280F27-TCXO module, PIN 2 is TCXOEN
2	GND	-		Power ground
Note: In Lora1280F27-TCXO module, PIN 2 is TCXOEN
2	TCXOEN	I	2.0-3.3V	Turn on TCXO: Pull up TCXOEN before controlling SX1280 to reset; Delay at least 3ms to wait for the TCXO startup to complete; 3. During the use of the 1280 module, TCXOEN must always maintain a high level; Turn off TCXO (if the module needs to enter sleep mode): Call the SetSleep() function to make the module enter the sleep mode; Delay at least 1ms to wait for the completion of module sleep; Pull down TCXOEN to turn off TCXO;
3	NRESET	I	0-3.3V	Chip reset trigger pin, active low
