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-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. |
