LoRa1281F27 : SX1281 500mW CE-RED & FCC ID Certified 2.4GHz LoRa Module With TCXO

LoRa1281F27 : SX1281 500mW CE-RED & FCC ID Certified 2.4GHz LoRa Module With TCXO

The LoRa module LoRa1281F27 have obtained CE and FCC certification.
FCC ID can be checked here: (FCC ID: 2AD66-LORA128XF27)
https://www.fcc.gov/oet/ea/fccid
LoRa1281F27 strictly uses lead-free process for production and testing, and meets RoHS and Reach standards.
This series of modules are designed based on the original sx1281 RF chip from Semtech, and the matching of the PA circuit makes the output power of the module up to 500mW(+27dBm).
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.
LoRa1281F27 has obtained CE-RED and FCC ID certification.

Pins of 2.4GHz LoRa Module LoRa1281F27

Note: When the power supply is 5V, the high level of all IO is 3.3V.

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
4	BUSY	O	0-3.3V	Status indicator pin (see SX1280/1281 specification for details)
