-AB01 (V2) belongs to Cubecell (TM) Series made by the Heltec team, mainly for LoRa/LoRaWAN node applications. -AB01 (V2) is based on ASR6052, the chip is 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 ®, can run the LoRaWAN protocol stably, and can easily connect lithium batteries and solar panels. -AB01 (V2) is a Dev-Board. Which is an upgraded version of -AB01, and can pin-to-pin placement with the previous version. Perfect for -Compatible! Based on ASR605x (ASR6501, ASR6502), those chips are already integrated the PSoC® 4000 series MCU (ARM® Cortex® M0+ Core) and SX1262. LoRaWAN 1.0.2 support LoRaWAN 1.0.2 support Onboard solar energy management system, can directly connect with a 5.5-7V solar panel Onboard SH1.25-2 battery interface, integrated lithium battery management system (charge and discharge management, overcharge protection, battery power detection, USB / battery power automatic switching) Integrated CP2102 USB to serial port chip, convenient for program downloading, debugging information printing Good impendence matching and long communication distance.
