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:

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:

• A basic working LoRaWAN platformio demo project is available at https://github.com/bertrik/cubecelldemo
• LoraWan example code from Heltec (not recommended)
