CubeCell (TM) is a new product series made by Heltec team, mainly for LoRa/LoRaWAN node applications.

CubeCell (TM) series is based on ASR605x (ASR6501, ASR6502), those chips are already integrated with the PSoC® 4000 series MCU (ARM® Cortex® M0+ Core) and SX1262. We have done a lot of migration and development, made it perfectly support Arduino®, can run the LoRaWAN protocol stably, can easily connect lithium batteries and solar panels.

HTCC-AB01 is a Dev-Board. Friendly designed for developers, easy to verify communication solutions.
