Key Features

  • TI CC2650 MCU/Transciever - ARM Cortex M3, Bluetooth+BLE, and 2.4GHz 802.15.4
  • Semtech SX1276 radio - 137MHz to 1020MHz supporting LoRa, FSK, GFSK, MSK, GMSK, and OOK
  • Micro USB - Bootloading and Console
  • Onboard 500mA 3.3V regulator


  • I have adapted the HAL of the official LoRaWAN stack for the CC2650 with TI-RTOS - LoRaWAN MAC
  • A spinoff from my example firmware can be found - LoRaBug_Firmware.
  • I have created a cross-platform serial bootloader tool that allows you to flash the LoRaBug using just a micro usb cable - ccbootutil
