Intro

This page is about the CubeCell board from heltec.org, 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

Hardware

Features:

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

Software

The CubeCell hardware works with (an export of) the basicmac device stack from Lacuna Space, just needs a pinmap definition, (see also https://www.thethingsnetwork.org/forum/t/heltec-cubecell-part-2/37225/72):

const lmic_pinmap lmic_pins = {
    .nss = RADIO_NSS,
    .tx = LMIC_CONTROLLED_BY_DIO2,
    .rx = LMIC_UNUSED_PIN,
    .rst = RADIO_RESET,
    .dio = {LMIC_UNUSED_PIN, RADIO_DIO_1, LMIC_UNUSED_PIN},
    .busy = RADIO_BUSY,
    .tcxo = LMIC_CONTROLLED_BY_DIO3,
};

Example code:
