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

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