Heltec LoRa Node Series
Applied for Meshtastic
Meshtastic® is a project that enables you to use inexpensive LoRa radios as a long range off-grid communication platform in areas without existing or reliable communications infrastructure. This project is 100% community driven and open source! Our ESP32 +LoRa series and nRF52840 series all support meshtastic.
BRANCHS
Heltec LoRa Node Series has Two Branches：
ESP32 + LoRa Series
ESP32 Series is more suitable for high-performance applications that require both Wi Fi and Bluetooth (including BLE) support.
- Base ESP32+SX1262
- Support LoRa/WiFi/BLE three communication modes.
- ESP32 is a powerfull SoC with 240MHz Tensilica LX6 dual-core & 1 ULP core, 600 DMIPS, 520KB SRAM.
- Fully supports Arduino ®， Can run LoRaWAN protocol stably.
nRF52840 + LoRa Series
nRF Series is more suitable for applications that require low-power wireless communication, especially BLE.
- nRF52840 + SX1262
- Meshtastic minimum operating current is 9mA, Tracker mode sleep current is 11uA
- Applied to extremely compact GNSS module L76K
- Hardware and open-source code specifically optimized for Meshtastic
