GC868-TC026 LoRa Spread Spectrum LLCC68 Bidirectional RF-chip Module 868MHz Serial Low Power Half-duplex Module UART Interface

1.1 Brief introduction

GC868-TC026 is a module use the RF-chip LLCC68 which is based on LORA modulation technique and a 32-bit MCU. 

The module is a half-duplex module highly integrated at 868MHz. The early stage of RF development has been completed by our company. 

Users can input data through the UART of the TX module, then the RX module can receive and output the date by UART, do not need to edit complex programs.
