Description:
The Mesh Node T114 integrates a dual-chip design featuring the nRF52840 and SX1262, supporting both LoRa and Bluetooth communication simultaneously. It offers optional GPS and display modules, and enables flexible power management through USB, lithium battery, and solar panel interfaces. Compared to the Heltec V3, it demonstrates superior low-power performance. Its six-layer PCB layout and optimized RF circuit design make it particularly well-suited and reliable for LoRa/LoRaWAN applications such as device tracking and remote monitoring systems. Furthermore, the T114 supports development via environments like Arduino and PlatformIO and is fully compatible with established open-source projects such as Meshtastic and MeshCore.
