LoRa128X-C1 : 2.4GHz Long-Range LoRa Wireless Transceiver Module For Extended Connectivity

LoRa128X-C1 : 2.4GHz Long-Range LoRa Wireless Transceiver Module For Extended Connectivity

The LoRa128X-C1 series is strictly manufactured and tested using lead-free processes, complying with RoHS and Reach standards.

This series of modules is designed based on the SX1280/SX1281 RF chips from the original US manufacturer Semtech. It utilizes LoRa modulation, effectively addressing the limitation of short communication distances in common 2.4GHz modules. Additionally, the modules integrate "time of flight" functionality for wireless distance measurement applications.

With the high penetration capability of the 2.4GHz frequency band combined with LoRa modulation, these modules offer excellent reception sensitivity and resistance to environmental interference, making them suitable for scenarios requiring long-distance 2.4GHz transmission.

LoRa128X-C1-TIP/LoRa128X-C1-TA:

LoRa128X-C1-IP/LoRa128X-C1-A:

Pin NO.	Pin name	Description
1	ANT	Connect with 50 ohm coaxial antenna
2,3,4,12	GND	Connected to the negative pole
5	NRESET	Chip reset trigger pin, active low
6	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 module needs to enter sleep mode): 1．Call the Set Sleep() function to put the module into sleep mode; 2．Delay for at least 1ms to wait for the module to complete its sleep process; 3．Pull down TCXOEN to disable TCXO; When using a regular crystal oscillator, leave this pin floating.
7	BUSY	Status indicator pin (refer to the SX1280/1281 datasheet for details).
8	DIO1	Direct connect chip pins, configurable as general-purpose I/O (function details can be found in the SX1280/1281 data sheet).
9	DIO2	Direct connect chip pins, configurable as general-purpose I/O (function details can be found in the SX1280/1281 data sheet).
10	DIO3	Directly connected chip pins, configurable as general-purpose I/O (function details can be found in the SX1280/1281 data sheet).
11	VCC	Connect the positive power supply (1.8-3.7V).
13	MISO	SPI Output for SPI data
