Project CubeCell
Low-power LoRaWAN Board
Status In progress

Last Update 2020-06-24


This page is about the CubeCell board from, aka HTCC-AB01

the github page for the Arduino code

What I'd like to investigate:

  • Does it have an RTC? YES, it appears so
  • Can we run the arduino-lmic library on this? NO, probably not in the short term.
  • Can we compile the code with platformio? YES
  • Use this board for my LoraBatBox
  • Video review by Andreas Spiess

Plans for immediate future:

  • get the LoRaWAN example running, in OTAA (or restored OTAA)
  • get LoRaWAN time synchronisation protocol running, figure out RTC API
  • investigate if wake up can be done by pin too (not just timer)



  • based on an ASR605x (ARM cortex M0+ core) + SX1262(?) radio chip
  • low power, only microamps sleep current
  • battery connection
  • solar cell connection
  • pinout


Example code:

What I'd like to do for a LoraBatBox:

  • register with OTAA (and remember the session keys)
  • wake up when there is movement sensed by the PIR
  • keep track of times when movement was detected (in wall-clock time)
  • send activity (say) once per hour to TTN
