HelTec’s new CubeCell series focuses on LoRa IoT Applications
HelTec CubeCell is a new product series made by HelTec. CubeCell series is based on ASR605x ICs (ASR6501, ASR6502), those chips are already blended with the PSoC 4000 series MCU (ARM Cortex M0+ Core) and Semtech SX1262 transceiver. It is perfectly Arduino-compatible and can run the LoRaWAN protocol reliably. Connecting lithium batteries and solar panels are also a notable feature that comes with this new CubeCell series.
LoRa (short for long range) devices, using LoRa Technology have a long-range, very power efficient wireless platform that is becoming the go-to technology for Internet of Things (IoT) networks worldwide. LoRa Technology and the open LoRaWAN protocol enable many smart IoT applications.
CubeCell series has three branches that can be listed as Module, Dev-Board and Capsule Sensor. The Dev-board can be controlled with AT commands. As mentioned earlier it also supports Arduino programming in Windows, Mac OS, and Linux.
