Product introduction

What’s this?

HTCC-AB02 is a developer-friendly designed Dev-Board, facilitating easy verification of communication solutions.

Main Features

CubeCell (TM) is a newly developed product series created by the Heltec team, specifically designed for LoRa/LoRaWAN node applications. The CubeCell (TM) series is built upon the ASR605x (ASR6501, ASR6502) chips, which are already integrated with the PSoC® 4000 series MCU (ARM® Cortex® M0+ Core) and SX1262. We have conducted extensive migration and development to ensure seamless support for Arduino®, stable operation of the LoRaWAN protocol, and easy connectivity with lithium batteries and solar panels. HTCC-AB02 is a developer-friendly designed Dev-Board, facilitating easy verification of communication solutions.
