LoRa-CC68-868 : LLCC68-Based LoRa Module With CE-RED Approved SPI Interface And ESD Protection

LoRa-CC68 LoRa module adopts Semtech's LLCC68 device and Industrial high-precision crystal oscillator, which make the module having ultra-low receiving current, low sleep current and good sensitivity -129dBm. It can wake up the external micro-controller periodically under low power consumption with built-in 64KHz oscillator . Antenna switch of the module is integrated and controlled by the RF chip, which saves the resources of the external MCU. Moreover, LoRa-CC68 has compact size and 22dBm (160mW) output power, which have great advantages in IoT and battery-powered applications.
LoRa-CC68 is produced and tested strictly using lead-free processes, and comply with RoHS and REACH standards.
LoRa-CC68 has obtained CE-RED certification @ 868MHz and obtained FCC ID certification @915MHz.
