1.Overview
The LoRa-CC68 wireless module uses Semtech's LLCC68 device, ultra-low receive current and sleep
current, and sensitivity of -129dBm. Built-in 64KHz crystal oscillator can wake up the microcontroller
periodically under low power consumption. The module antenna switch is integrated and controlled by
the chip, which saves the resources of the external MCU. The compact size and 8~10dBm output power
have great advantages in IoT and battery-powered applications.
LoRa-CC68 comply with lead-free craft in production and testing and meets RoHS and Reach standards.

7. Communication Antenna
Antenna is very important for RF communication, its performance will affect the communication
directly. To ensure module in the best performance, we suggest to use the our antenna.
★To ensure modules get the best performance, user must obey the following principles when using
the antennas：
Put the antenna away from the ground and obstacles as possible as you could；
If you choose the sucker antenna, pull straight the lead wire as possible as it can be, the sucker
under arches should be attached on the metal object.

11.Common problem
a) Why can't the normal communication between the modules?
1) The power connection is wrong and the module is not working normally;
2) Check whether the frequency bands of each module and other RF parameters are
consistent;
3) Whether the module is damaged.
b) Why is the transmission distance not far?
1) The power supply ripple is too large;
2) The antenna type is not matched or installed incorrectly;
3) Surrounding co-channel interference;
4) The surrounding environment is harsh and there are strong interference sources.

Appendix 2:Demo Board
The module is equipped with a standard DEMO board for customer to debug the program and test
distance. The power supply voltage range: 3.3V~6.0V. It shows as below:
The LCD Full Segment is as below:
The users can set the parameters of the RF module such as frequency /transmitter power /
transmission data rate through the buttons.

Working Mode
1) Tx normal mode: send data packets regularly (in the setting mode, data packets will not be sent
temporarily);
2) Rx normal mode: Power on and enter the receiving state, receive data packets, and then send out
the correctly received data packets;
3) Tx Test Mode: RF module continuously transmit signal;
4) Rx Test Mode: RF module is always in Rx mode;
5) Standby Mode: RF module is always in standby state.
Button Operation
1) [SET] Button
Press the key to enter the setting mode. If the last parameter is set, the key will exit the setting mode.
2) UP /Down Button
In setting mode,press to modify the corresponding setting parameters.
Note: The DEMO board has FLASH memory inside, all the setting parameters will behave
automatically and keep unchanged even power-off.
