HTCC-AB01 (V2) is part of the Cubecell series developed by the Heltec team, designed primarily for LoRa/LoRaWAN node applications. This development board is based on the ASR6052 chip, which integrates the PSoC® 4000 series MCU (ARM® Cortex® M0+ core) and SX1262. Extensive development and optimization have been performed to ensure full Arduino compatibility, stable LoRaWAN 1.0.2 protocol operation, and seamless integration with lithium batteries and solar panels.HTCC-AB01 (V2) is an upgraded version of the HTCC-AB01 and maintains pin-to-pin compatibility with the previous model. It features an onboard solar energy management system that supports direct connection to a 5.5-7V solar panel. The board includes a SH1.25-2 battery interface with an integrated lithium battery management system for charge and discharge control, overcharge protection, battery level monitoring, and automatic power switching between USB and battery sources.Equipped with the CP2102 USB-to-serial converter, the board simplifies firmware uploading and enables easy debugging via serial output. Optimized RF impedance matching ensures reliable long-range communication performance.Note: Product appearance may vary slightly between batches, but functionality remains unchanged.
