Series Comparison
| Feature / Series | ESP32 Series | CubeCell Series (ASR) | nRF Series |
|---|---|---|---|
| MCU | ESP32 (Dual-core Xtensa) | ASR6501/ASR6502 (ARM Cortex-M0+ + LoRa) | nRF52840 (ARM Cortex-M4 + BLE + external LoRa module) |
| Main Connectivity | Wi-Fi + Bluetooth + LoRa | LoRaWAN only | BLE + LoRa |
| Power Consumption | Higher (better for continuous power supply) | Ultra-low power (ideal for battery operation) | Low power (better than ESP32, slightly higher than CubeCell) |
| Common Features | All three support LoRa communication, come with Heltec official open-source libraries, feature high integration (power management, antenna interface, some with OLED), and target IoT prototyping and deployment. | ||
